Safety Rules
PRIMEPACT 50 and 70 (50Hz) Recreational Vehicle Generators
SAVE THESE INSTRUCTIONS – The manufacturer suggests that these rules for safe
operation be copied and posted in potential hazard areas of the recreational vehicle.
Safety should be stressed to all operators and potential operators of this equipment.
GENERAL HAZARDS
WARNING:
contains chemicals known to the state
of California to cause cancer, birth
defects or other reproductive harm.
The engine exhaust from this product
• For safety reasons, Generac recommends
that the installation, initial start-up and mainte-
nance of this equipment is carried out by a
Generac Authorized Service Dealer.
• The engine exhaust fumes contain carbon monox-
ide, which can be DEADLY. This dangerous gas, if
breathed in sufficient concentrations, can cause
unconsciousness or even death. This exhaust sys-
tem must be installed properly, in strict compli-
ance with applicable codes and standards.
Following installation, you must do nothing that
might render the system unsafe or in noncompli-
ance with such codes and standards. The genera-
tor compartment must be completely vapor sealed
from the vehicle interior. There must be no possi-
bility of exhaust fumes entering the vehicle interi-
or. Never operate this equipment with a leaking or
defective exhaust system.
• Keep hands, feet, clothing, etc., away from drive
belts, fans, and other moving or hot parts. Never
remove any drive belt or fan guard while the unit is
operating.
• Adequate, unobstructed flow of cooling and venti-
lating air is critical to correct generator operation
and is required to expel toxic fumes and fuel
vapors from the generator compartment. Without
sufficient cooling airflow, the engine/generator
quickly overheats, which causes serious damage to
the generator. Do not alter the installation or per-
mit even partial blockage of ventilation provisions,
as this can seriously affect safe operation of the
generator.
WARNING:
This product contains or emits chemicals
known to the state of California to cause
cancer, birth defects or other reproductive harm.
Study these SAFETY RULES carefully before
installing, operating or servicing this equipment.
Become familiar with this manual and with the unit.
The generator can operate safely, efficiently and reli-
ably only if it is properly installed, operated and main-
tained. Many accidents are caused by failing to follow
simple and fundamental rules or precautions.
Generac cannot possibly anticipate every possible
circumstance that might involve a hazard. The warn-
ings in this manual, and on tags and decals
affixed to the unit, are, therefore, not all-inclusive. If
you use a procedure, work method or operating tech-
nique Generac does not specifically recommend, you
must satisfy yourself that it is safe for you and others.
You also must make sure the procedure, work
method or operating technique that you choose does
not render the generator unsafe.
Despite the safe design of this generator,
operating this equipment imprudently, neglecting
its maintenance or being careless can cause
possible injury or death. Permit only responsible
and capable persons to operate or maintain this
equipment.
• When working on this equipment, remain alert at
all times. Never work on the equipment when you
are physically or mentally fatigued.
• Inspect the generator regularly, and contact your
nearest Generac Authorized Service Dealer immedi-
ately for parts needing repair or replacement.
• Before performing any maintenance on the genera-
tor, disconnect its battery cables to prevent acci-
dental start up. Disconnect the cable from the bat-
tery post indicated by a NEGATIVE, NEG or (–)
first. Reconnect that cable last.
• Never use the generator or any of its parts as a
step. Stepping on the unit can stress and break
parts, and may result in dangerous operating con-
ditions from leaking exhaust gases, fuel leakage,
oil leakage, etc.
Potentially lethal voltages are generated by
these machines. Ensure all steps are taken to
render the machine safe before attempting to
work on the generator.
Parts of the generator are rotating and/or hot
during operation. Exercise care near running
generators.

PRIMEPACT 50 and 70 (50Hz) Recreational Vehicle Generators
ELECTRICAL HAZARDS
FIRE HAZARDS
• The generator covered by this manual produces
dangerous electrical voltages and can cause fatal
electrical shock. Avoid contact with bare wires, ter-
minals, connections, etc., while the unit is running.
Ensure all appropriate covers, guards and barriers
are in place before operating the generator. If you
must work around an operating unit, stand on an
insulated, dry surface to reduce shock hazard.
• Do not handle any kind of electrical device while
standing in water, while barefoot, or while hands
or feet are wet. DANGEROUS ELECTRICAL
SHOCK MAY RESULT.
• During installation onto the vehicle, have the genera-
tor properly grounded (bonded) either by solid
mounting to the vehicle frame or chassis, or by
means of an approved bonding conductor. DO NOT
disconnect the bonding conductor, if so equipped.
DO NOT reconnect the bonding conductor to any
generator part that might be removed or disassem-
bled during routine maintenance. If the grounding
conductor must be replaced, use only a flexible con-
ductor that is of No. 8 American Wire Gauge (AWG)
copper wire minimum.
• For fire safety, the generator must be installed and
maintained properly. Installation always must
comply with applicable codes, standards, laws and
regulations. Adhere strictly to local, state and
national electrical and building codes. Comply
with regulations the Occupational Safety and
Health Administration (OSHA) has established.
Also, ensure that the generator is installed in
accordance with the manufacturer’s instructions
and recommendations. Following proper installa-
tion, do nothing that might alter a safe installation
and render the unit in noncompliance with the
aforementioned codes, standards, laws and regu-
lations.
• Keep a fire extinguisher in the vehicle at all times.
Extinguishers rated “ABC” by the National Fire
Protection Association are appropriate for use on
the recreational vehicle generator electrical system.
Keep the extinguisher properly charged and be
familiar with its use. If you have any question per-
taining to fire extinguishers, consult your local fire
department.
• In case of accident caused by electric shock, imme-
diately shut down the source of electrical power. If
this is not possible, attempt to free the victim from
the live conductor. AVOID DIRECT CONTACT
WITH THE VICTIM. Use a nonconducting imple-
ment, such as a rope or board, to free the victim
from the live conductor. If the victim is uncon-
scious, apply first aid and get immediate medical
help.
• Never wear jewelry when working on this equip-
ment. Jewelry can conduct electricity resulting in
electric shock, or may get caught in moving com-
ponents causing injury.
EXPLOSION HAZARDS
• Do not smoke around the generator. Wipe up any
fuel or oil spills immediately. Ensure that no com-
bustible materials are left in the generator com-
partment, or on or near the generator, as FIRE or
EXPLOSION may result. Keep the area surround-
ing the generator clean and free from debris.
• Gasoline is extremely FLAMMABLE and its vapors
are EXPLOSIVE. Do not permit smoking, open
flame, sparks or any source of heat in the vicinity
while handling gasoline. Comply with all laws gov-
erning the storage and handling of gasoline.

1.2 GENERATOR APPLICABILITY
1.3 INSTALLATION
These generators have been designed and manufac-
tured for supplying electrical power for recreational
vehicles. You should not modify the generator or use
it for any application other than for what it was
designed. If there are any questions pertaining to its
application, write or call the factory. Do not use the
unit until you have been advised by a competent
authority.
This manual has been prepared under the assump-
tion that a competent, qualified technician installed
the generator into a recreational vehicle. We also
assume the installer complied with all applicable
codes, standards and regulations pertaining to instal-
lation.
Owners/Operators should make sure nothing is done
during installation that might render the unit unsafe
or in noncompliance with applicable codes standards
and instructions. They should be sure the unit has
been installed to allow adequate ventilation for cool-
ing and exhaust air.
For fire safety, the generator must have been
properly installed in compliance with ANSI
119.2-1975/NFPA 501C-1974, “Standard for
Recreational Vehicles, Part III – Installation of
Electrical Systems.” The generator also must
have been installed in strict compliance with
the manufacturer’s detailed installation instruc-
tions. After installation, do nothing that might
render the unit in noncompliance with such
codes, standards and instructions.
1.4 SAFETY
Before attempting to use the generator set, carefully
read the “Safety Rules” section of this manual.
Comply strictly with these rules to prevent accidents
and damage to equipment and/or property. We sug-
gest copying and posting the “Safety Rules” in poten-
tial hazard areas of the vehicle. Stress safety to all
operators and potential operators of this equipment.
1.2.1 PRIMEPACT 70
N
1.5 GENERATOR AC
Use this generator to supply electrical power for
operating 230-volt, single-phase, 50 Hertz, AC elec-
trical loads. These loads can require up to 7,000
watts (7.0 kW) of power, but cannot exceed 30.4 AC
amperes of current at 230 volts.
CONNECTION SYSTEM
This generator set is equipped with dual stator AC
power windings. These two-stator windings supply
electrical power to customer electrical loads.
NOTE:
1.2.2 PRIMEPACT 50
N
One side of the winding is grounded.
Use this generator to supply electrical power for
operating 230 volt, single phase, 50 Hertz AC electri-
cal loads. These loads can require up to 5,000 watts
(5.0 kW) of power, but cannot exceed 20.8 amperes of
current at 230 volts.
Figure 1.1 – Connections for 230 Volts Only
Do not overload the generator. Some installa-
tions may require that electrical loads be alter-
nated to avoid overloading. Applying exces-
sively high electrical loads may damage the
generator and may shorten its life. Add up the
rated watts of all electrical lighting, appliance,
tool and motor loads the generator will power
at one time. This total should not be greater
than the wattage capacity of the generator. If
an electrical device nameplate gives only volts
and amps, multiply volts times amps to obtain
watts (volts x amps = watts). Some electric
motors require more watts of power (or amps
of current) for starting than for continuous
operation.

1.6.1 FUEL REQUIREMENTS
N
These generators are equipped with a gasoline fuel sys-
tem. Depending on the installation, the generator may
have either a separate fuel tank, or it may “share” the
vehicle engine’s fuel tank.
NOTE:
Some installations using a “shared” fuel tank may
have a generator fuel pickup tube that is shorter
than the vehicle engine’s pickup tube. Such an
arrangement causes the generator engine to “run
out of gas” while adequate fuel for the vehicle
remains in the tank.

Generac does not recommend using any
gasoline containing alcohol (such as “gasohol”).
If you use any gasoline containing alcohol, it
must not contain more than 10 percent ethanol,
and it must be removed from the generator
during storage. Do NOT use any gasoline
containing methanol. If you use gasoline with
alcohol, inspect more frequently for fuel leaks
and other abnormalities.
1.6.2 ENGINE OIL REQUIREMENTS
N
Use only high quality detergent oil classified “For
Service SF” and with an oil viscosity rating of SAE
10W-30 oil. Do not pour in any additives to the rec-
ommended oil. Engine crankcase capacity is 1.4
liters. See Section 3.2 on page 11 for oil level check
and filing procedures.

PRIMEPACT 50 and 70 (50Hz) Recreational Vehicle Generators
2.1 GENERATOR CONTROL PANEL
2.2 OPTIONAL REMOTE
The following features are mounted on the generator
control panel (Figure 2.1):
START/STOP PANEL
A remote mounted Start/Stop Panel (Figure 2.2) is
available that allows you to start and stop the gener-
ator engine conveniently from inside the vehicle. The
remote panel includes a Start/Stop switch, hour
meter, generator run lamp and a wire harness.
Figure 2.1 – Generator Control Panel
Figure 2.2 — Optional Remote Panel
(Models 004057 and 004184)
2.1.1 FUEL PRIMER
N
Before starting a cold engine (if it has not been start-
ed in more than two weeks), you must press this
switch for approximately five seconds to bring fuel
from the tank to the fuel pump. This rocker type
switch springs back into its original position when
you release it.
2.3 AUTOMATIC CHOKE
This engine is equipped with an automatic choke that
consists of two main components: a choke solenoid
and prechoke.
2.3.1 CHOKE SOLENOID
N
During engine cranking (Start/Stop switch at
START), a solid-state choke module signals the
choke solenoid to activate and cycle (choke on/choke
off) until the engine starts. The choke solenoid thus
opens and closes the carburetor choke valve only
when the engine is cranking. When the engine starts,
the choke stops cycling.
2.1.2 START/STOP SWITCH
N
To crank and start the engine, hold this switch in the
START position. Release the switch when the engine
starts. To stop an operating engine, press and hold
the switch in the STOP position until the engine shuts
off. The switch center position is the RUN position.
2.1.3 FUSE
N
2.3.2 PRECHOKE
N
The fuse protects the engine’s DC control circuit
against electrical overload. If the fuse element has
melted open due to overloading, the engine cannot be
cranked. If you must replace the fuse, use only an
identical replacement.
The choke system also has a temperature-sensitive
metal strip that adjusts choke valve angle according
to ambient temperatures (i.e., in cold ambient tem-
peratures, choke valve closes more). Once the engine
starts, an element heats the temperature-sensitive
strip to a normal operating condition, opening the
choke valve. This may take about three minutes in
cooler weather.
2.1.4 MAIN BREAKER
N
The main breaker protects the generator’s AC output
circuit against overload and provides a method of
turning OFF the generator’s 230-volt AC output to the
vehicle circuits. These generators have either a 25
Amp, 2-Pole circuit breaker (PP50) or a 30 Amp
2-Pole circuit breaker (PP70).

Section 2 – Operation
PRIMEPACT 50 and 70 (50Hz) Recreational Vehicle Generators
2.4 BEFORE STARTING THE ENGINE
NOTE:
The generator engine gives off DEADLY carbon
monoxide gas through its exhaust system. This
dangerous gas, if breathed in sufficient concen-
trations, can cause unconsciousness or even
death. Never operate the generator set with
the vehicle inside any garage or other enclosed
area. DO NOT OPERATE THE GENERATOR IF THE
EXHAUST SYSTEM IS LEAKING OR HAS BEEN
DAMAGED. SYMPTOMS OF CARBON MONOX-
IDE POISONING ARE (a) inability to think coher-
ently; (b) vomiting; (c) twitching muscles; (d)
throbbing temples; (e) dizziness; (f) headaches;
(g) weakness; and (h) sleepiness. IF YOU FEEL
ANY OF THESE SYMPTOMS, MOVE INTO FRESH
AIR IMMEDIATELY. IF SYMPTOMS PERSIST, GET
MEDICAL HELP.
Instructions and information in this manual
assume the generator has been properly installed,
connected, serviced, tested and adjusted by a
qualified installation technician or installation
contractor.
2.4.1 INSTALLATION
N
Generator installation must have been properly com-
pleted so it complies with all applicable codes, stan-
dards and regulations and with the manufacturer's
recommendations.
2.4.2 ENGINE LUBRICATION
N
Have the engine crankcase properly serviced with the
recommended oil before starting. Refer to Section 1.6.3
(Page 6) and Sections 3.1 and 3.2 (Page 11) for oil ser-
vicing procedures and recommendations.
2.5 STARTING THE GENERATOR
To start the generator from either the generator con-
trol panel or from the optional remote panel, proceed
as follows:
1. Turn OFF electrical loads using the means pro-
vided in your vehicle (such as a main line circuit
breaker or transfer switch).
Any attempt to crank or start the engine before
you have properly serviced it with the recom-
mended oil may result in an engine failure.
NOTE:
2.4.3 FUEL SUPPLY
The engine must have an adequate supply of proper
fuel to operate. Before starting it, check that sufficient
fuel is available.
N
If starting from the generator control panel, turn
OFF loads by setting the generator’s main circuit
breaker to the OFF (or open) position. If starting
from a remote panel, turn OFF loads using the
means provided in the vehicle (such as a main cir-
cuit breaker). Electrical load circuits will be
turned ON after the generator has started, stabi-
lized and warmed up.
NOTE:
Depending on the installation, the generator may
have either a separate fuel tank, or it may “share”
the vehicle engine’s fuel tank.
2. If you have not started the engine in more than
two weeks, press the Fuel Pump Primer switch
and hold it for about five seconds to prime the
fuel system. However, if the engine is warm, skip
Step 2.
3. Hold the engine Start/Stop switch in the START
position to crank the engine. Release the switch
when the engine starts.
2.4.4 COOLING AND VENTILATING AIR
N
Air inlet and outlet openings in the generator com-
partment must be open and unobstructed for contin-
ued proper operation. Without sufficient cooling and
ventilating airflow, the engine/generator quickly over-
heats, which causes it to shut down and may damage
the generator.
2.4.5 ENGINE EXHAUST GAS
N
If the engine does not start after it has been
cranking for 15 seconds, release the Start/Stop
switch and try again. Holding the switch for
longer than 15 seconds can damage the
starter motor.
Before starting the generator engine, you should be
sure there is no way for exhaust gases to enter the
vehicle interior and endanger people or animals.
Close windows, doors and other openings in the vehi-
cle that, if open, might permit exhaust gases to enter
the vehicle.
4. Let the engine run at no-load for a few minutes to
stabilize and warm up.
5. Turn ON electrical loads using the means
provided (such as a main circuit breaker or
transfer switch).

PRIMEPACT 50 and 70 (50Hz) Recreational Vehicle Generators
2.6 STOPPING THE GENERATOR
2.8 PROTECTION SYSTEMS
1. Turn OFF all electrical loads using the means
provided (such as a main circuit breaker or
transfer switch).
2.8.1 LOW OIL PRESSURE SWITCH
N
This switch (Figure 2.3) has normally open (N.O.) con-
tacts that are held open by engine oil pressure during
cranking and operating. Should oil pressure drop
below a preset level, switch contacts close, and the
engine automatically shuts down. The unit should not
be restarted until oil is added.
2. Let generator run at no-load for a few minutes, to
stabilize internal engine generator temperatures.
3. Place the Start/Stop switch in its STOP position.
2.7 APPLYING LOADS TO GENERATOR
When applying electrical loads to the generator,
observe these guidelines:
2.8.2 HIGH TEMPERATURE SWITCH
N
• Before applying electrical loads, let the generator
stabilize and warm up for a minute or two.
• DO NOT overload the generator.
This switch (Figure 2.3), which has normally open
(N.O.) contacts, is mounted near the oil filter. The
contacts close if the temperature should exceed
approximately 284º F (140º C), initiating an engine
shutdown.
2.7.1 LETTING THE ENGINE STABILIZE
N
The generator supplies correct rated voltage only at
the proper governed speed. Some electrical appli-
ances may be extremely sensitive to voltage. Incorrect
voltages can damage such appliances.
Figure 2.3 – Low Oil Pressure and
High Temperature Switches
If electrical loads are applied at reduced operating
speeds, such loads imposed on the engine when suffi-
cient power is not available may shorten engine life.
Never turn ON electrical loads until after the generator
engine has started and stabilized at no-load.
2.7.2 DO NOT OVERLOAD THE GENERATOR
N
You can read the rated wattage/amperage capacity of
your generator on the generator data decal (see
Section 1.1 on Page 4).
Applying electrical loads in excess of the unit’s rated
capacity will cause the engine/generator to automati-
cally shut down.
To avoid overloading, add up the wattage of all con-
nected electrical lighting, appliance, tool and motor
loads. This total should not be greater than the gen-
erator’s rated wattage capacity.
2.8.3 FIELD BOOST
N
The Controller Circuit Board houses a field boost
diode and resistor. These two components are part of
a “field boost” circuit (Figure 2.4). During engine
cranking only, a positive DC (battery) voltage is deliv-
ered through the diode, resistor, brushes and slip
rings, and the generator rotor. Application of this
voltage to the rotor “flashes the field” whenever it is
started. Flashing of the field each time the generator
starts makes sure that a sufficiently strong magnetic
field is available to produce “pickup” voltage in the
stator windings.
• Most lighting, appliance, tool and motor loads indi-
cate their required watts on their nameplate or
data plate. For light bulbs, simply note the wattage
rating of the bulb.
• If a load does not show its rated wattage, multiply
that load’s rated VOLTS times AMPS to obtain
WATTS.
• Induction type motors (such as those that run the
vehicle’s furnace fan, refrigerator, air conditioner,
etc.) need about 2-1/2 times more watts of power
for starting than for running (for a few seconds
during motor starting). Be sure to allow for this
when connecting electrical loads to the generator.
First, figure the watts needed to start electric
motors in the system. To that figure, add the run-
ning wattages of other items that will be operated
by the generator.
• Do not apply heavy electrical loads for the first two
or three hours of operation.

2.9 ADDITIONAL INFORMATION
2.9.1 25-HOUR BREAK-IN PERIOD
N
The first 25 hours of operation is the break-in period
for the generator. Properly breaking in the generator
is essential to minimize fuel consumption and pro-
vide maximum engine performance. During this 25-
hour break-in period, follow this procedure:
• Run the unit at varying electrical loads to help seat
the engine piston rings properly.
• Check the engine oil level frequently. Add oil if
needed. It is normal for the generator engine to
consume more oil than is normal until the piston
rings have properly seated.
• For the 75-hour operation following the break-in
period, avoid light electrical loads. Load the
generator at 50 percent (or more) of its rated
wattage capacity. Repeated light loads during these
75 hours can cause improper seating of engine pis-
ton rings, resulting in blowby and high oil con-
sumption.
2.8.4 OVERVOLTAGE PROTECTION
N
A solid-state voltage regulator (Figure 2.5) controls
the generator’s AC output voltage. This regulator sup-
plies an excitation current to the rotor. By regulating
the rotor’s excitation current, the strength of its mag-
netic field is regulated and, in turn, the voltage deliv-
ered to connected electrical loads is controlled. When
the AC frequency is 50 Hertz, voltage is regulated at
115 volts.
• After operating the unit for 25 hours, complete the
tasks recommended under Section 2.10.2.
2.9.2 25-HOUR CHECK-UP
N
NOTE:
After the 25-hour break-in period, contact a Generac
Authorized Service Dealer for the following mainte-
nance. The vehicle owner is responsible for any
charges:
The solid state voltage regulator is only con-
nected across 1/2 of the output winding.
Figure 2.5 – Solid State Voltage Regulator
• Change the engine crankcase oil and oil filter.
• Inspect the cooling and ventilation openings.
• Check the engine ignition system.
• Inspect the entire electrical system.
• Inspect the engine exhaust system.
2A
2.9.3 OPERATION IN HIGH GRASS
N
OR BRUSH
Never operate the generator while the vehicle
is parked over high grass, weeds, brush,
leaves or any other combustible substance.
Such materials can ignite and burn from the
heat of the exhaust system. The generator
exhaust system becomes extremely hot dur-
ing operation and remains hot for a long time
after it has shut down.
The voltage regulator also incorporates a “voltage
surge protection circuit.” This circuit prevents trou-
blesome surges in the generator AC output voltage.
Voltage surge is a common cause of damage to elec-
tronic equipment.

To change the oil and/or oil filter, proceed as
follows:
1. Run the engine until it is thoroughly warmed up
(at least five minutes) then shut OFF
the engine.
2. With the engine still warm from running, remove
the oil drain plug (Figure 3.1). Drain the oil into
a suitable container.
3. After the oil has drained, replace the oil drain plug.
(If only changing the oil, go to step 7.)
4. With the oil drained, remove the old oil filter by
turning it counterclockwise (Figure 3.2).
5. Apply a light coating of clean engine oil to the gas-
ket of the new filter.
6. Screw the new filter on by hand until its gasket
lightly contacts the oil filter adapter. Then, tight-
en the filter an additional 3/4 to one turn.

3.6 FUEL FILTER (GASOLINE ONLY)
3.8 CLEANING THE GENERATOR
Keep the generator set as clean and dry as possible.
Protect the unit against excessive dust, dirt, corrosive
vapors, road splash, etc. Permitting dirt and mois-
ture to accumulate on generator windings will have
an adverse effect on the insulation resistance of those
windings.
Remove and replace the fuel filter (Figure 3.6)
once each year or every 100 hours of operation,
whichever comes first.
Figure 3.6 – Fuel Filter
When moisture is allowed to remain in contact with
windings, some of the moisture will be retained in
voids and cracks in the insulation. This causes a
reduced insulation resistance and will eventually
cause problems. Dirt will make the problem worse,
since dirt tends to hold moisture in contact with
windings. Salt (as from sea air) also will worsen the
problem since it tends to absorb moisture from the
air. Salt and moisture, when combined, form a good
electrical conductor.

CUSTOMER FUEL CONNECTION
3.7 SPARK ARRESTOR MUFFLER
Do NOT use a forceful spray of water to clean
the generator. Water will enter the generator
interior and cause problems, and may also cont-
aminate the generator fuel system.
If the generator is not equipped with a spark arrestor
exhaust muffler and is to be used on any forest cov-
ered, brush covered or grass covered unimproved
land, you may have to install a spark arrestor. The
spark arrestor must be maintained in effective work-
ing order by the vehicle owner/operator.
3.9 BATTERY MAINTENANCE
All lead-acid batteries will discharge when not in use.
The generator battery should be inspected as follows:
For assistance in ordering, installing and maintaining
spark arrestor exhaust mufflers, contact your nearest
Generac Authorized Service Dealer.
3.9.1 WEEKLY
N
Exhaust mufflers supplied by Generac are spark
arrestor types. Generac exhaust mufflers for recre-
ational vehicle generators do not have a spark
arrestor screen, but are of the more efficient “toroid”
or “swirl” type. To remove carbon and combustion
deposits from such mufflers, remove the plug from
the muffler and run the engine for approximately 15
minutes. Shut down the engine, let the muffler cool
and install the plug.
• Inspect the battery posts and cables for tightness
and corrosion. Tighten and clean as necessary.
• Check the battery fluid level of unsealed batteries
and, if necessary, fill with Distilled Water Only. Do
not use tap water in batteries.
3.9.2 EVERY SIX MONTHS
N
• Have the state of charge and condition checked.
This should be done with an automotive-type bat-
tery hydrometer.
NOTE:
Be sure to reinstall the muffler plug tightly.
Engine vibration could cause a loose plug to
fall out. Without the plug in place, hot engine
exhaust is directed out the opening. This hot
exhaust, depending on the installation, could
be directed to areas not able to withstand the
extreme heat such as wooden floor boards or
other flammable material. This could result in a
fire.
Servicing of the battery is to be performed or
supervised by personnel knowledgeable of batter-
ies and the required precautions. Keep unautho-
rized personnel away from batteries.
Damage will result if the battery connections are
made in reverse.

3.10 MAJOR SERVICE MANUAL
To obtain a service manual for your generator, con-
tact Generac or your nearest Generac Authorized
Service Dealer. Make sure to identify your MODEL
NUMBER and SERIES.
Do not dispose of the battery in a fire. The
battery is capable of exploding. Storage batter-
ies give off explosive hydrogen gas. This gas
can form an explosive mixture around the bat-
tery for several hours after charging. The
slightest spark can ignite the gas and cause an
explosion. Such an explosion can shatter the
battery and cause blindness or other injury.
Any area that houses a storage battery must be
properly ventilated. Do not allow smoking,
open flame, sparks, or any spark producing
tools or equipment near the battery. Discharge
static electricity from your body before touch-
ing the battery by first touching a grounded
metal surface.
3.11 DRIVE BELT
The engine drives the generator rotor by means of a
pulley and drive belt arrangement. The drive belt and
pulleys are warranted for the life of the generator. Drive
belt tension was properly adjusted before the unit was
shipped from the factory. If you suspect that drive belt
tension is incorrect, contact a Generac Authorized
Service Dealer.
3.12 EXERCISING THE GENERATOR
Generac recommends that you start and operate the
generator at least once every seven days. Let
the unit run for at least 30 minutes to “exercise”
the engine.
A battery presents a risk of electrical shock
and high short circuit current. The following
precautions are to be observed when working
on batteries:
• Remove watches, rings or other metal objects;
• Use tools with insulated handles;
3.13 OUT OF SERVICE PROCEDURE
• Wear rubber gloves and boots;
3.13.1 REMOVAL FROM SERVICE
N
• Do not lay tools or metal parts on top of the
battery;
• Disconnect any charging source prior to connecting
or disconnecting battery terminals; and
• Do not use any jumper cables or booster battery to
crank and start the generator engine. If any battery
has discharged, remove it for recharging.
If you cannot exercise the generator every seven days,
and it is to be out of service longer than 30 days, pre-
pare the generator for storage as follows:
1. Start the engine and let it warm up.
2. Close the fuel shutoff valve in the fuel supply line
and allow the unit to shut down.
3. While the engine is still warm from running,
drain the oil completely. Refill the crankcase with
SAE 10W-30 oil having API classification “For
Service SF.”
4. Attach a tag to the engine indicating the viscosity
and classification of the oil in the crankcase.
5. Remove the spark plug and pour two or three
tablespoons of clean, fresh engine oil into the
spark plug threaded openings. Reinstall and
tighten the spark plug.
Do not open or mutilate the battery. Released
electrolyte has been known to be harmful to
the skin and eyes, and to be toxic.
The electrolyte is a dilute sulfuric acid that is
harmful to the skin and eyes. It is electrically
conductive and corrosive. The following
procedures are to be observed:
• Wear full eye protection and protective clothing;
• Where electrolyte contacts the skin, wash it off
immediately with water;
• Where electrolyte contacts the eyes, flush
thoroughly and immediately with water and seek
medical attention; and
6. Remove the battery and store it in a cool, dry
room on a wooden board. Never store the battery
on any concrete or earthen floor.
7. Clean and wipe the entire generator.
• Spilled electrolyte is to be washed down with an
acid neutralizing agent. A common practice is to
use a solution of 1 pound (500 grams) bicarbonate
of soda to 1 gallon (4 liters) or water. The bicar-
bonate of soda solution is to be added until the
evidence of reaction (foaming) has ceased. The
resulting liquid is to be flushed with water and the
area dried.

Safety Rules
PRIMEPACT 50 and 70 (50Hz) Recreational Vehicle Generators
DANGER: For fire safety, installation of a generator into a recreational vehicle must comply strictly
with article 551, NFPA 70; ANSI C1-1975; AND, ANSI A119.2-1975/NFPA 501C “Standard for
Recreational Vehicles” (Part 3, “Installation of Electrical Systems”). In addition, installation must
comply with the manufacturer’s instructions and recommendations.
NOTICE TO INSTALLER
GENERAL HAZARDS
These Installation Instructions have been published
by Generac to aid in the installation of the products
• For safety reasons, Generac recommends
that the installation, initial start-up and mainte-
nance of this equipment is carried out by a
Generac Authorized Service Dealer.
described in this manual. Generac assumes that
installation personnel are familiar with the proce-
dures for installing such products, or similar prod-
ucts that Generac manufactures. Generac also
assumes that personnel have been trained in the rec-
ommended installation procedures for these prod-
ucts and that such training includes (a) use of com-
mon hand tools, (b) use of special Generac tools, and
(c) use of any tools and/or equipment from other sup-
pliers.
• The engine exhaust fumes contain carbon monox-
ide, which can be DEADLY. This dangerous gas, if
breathed in sufficient concentrations, can cause
unconsciousness or even death. This exhaust sys-
tem must be installed properly, in strict compli-
ance with applicable codes and standards.
Following installation, you must do nothing that
might render the system unsafe or in noncompli-
ance with such codes and standards. The genera-
tor compartment must be completely vapor sealed
from the vehicle interior. There must be no possi-
bility of exhaust fumes entering the vehicle interi-
or. Never operate this equipment with a leaking or
defective exhaust system.
• Keep hands, feet, clothing, etc., away from drive
belts, fans, and other moving or hot parts. Never
remove any drive belt or fan guard while the unit is
operating.
• Adequate, unobstructed flow of cooling and venti-
lating air is critical to correct generator operation
and is required to expel toxic fumes and fuel
vapors from the generator compartment. Without
sufficient cooling airflow, the engine/generator
quickly overheats, which causes serious damage to
the generator. Do not alter the installation or per-
mit even partial blockage of ventilation provisions,
as this can seriously affect safe operation of the
generator.
Generac cannot possibly know of and advise the
recreational vehicle trade of all conceivable methods,
procedures or techniques by which to perform an
installation. Nor can Generac anticipate every possi-
ble hazard that might result from each installation
method, procedure or technique. Generac has not
undertaken any such wide evaluation. Therefore,
people who use a method, procedure or technique
that Generac does not specifically recommend must
first completely satisfy themselves that their safety,
the safety of the vehicle's occupants and the product's
safety is not endangered by the method, procedure or
technique selected.
Information, illustrations, specifications, etc., con-
tained in these Installation Instructions are based on
the latest information available at the time of publi-
cation. Every effort has been expended to be sure that
such data is both accurate and current. However, the
manufacturer reserves the right to change, alter or
otherwise improve this product at any time without
prior notice.
• When working on this equipment, remain alert at
all times. Never work on the equipment when you
are physically or mentally fatigued.
• Before performing any maintenance on the genera-
tor, disconnect its battery cables to prevent acci-
dental start up. Disconnect the cable from the bat-
tery post indicated by a NEGATIVE, NEG or (–)
first. Reconnect that cable last.
• Never use the generator or any of its parts as a
step. Stepping on the unit can stress and break
parts, and may result in dangerous operating con-
ditions from leaking exhaust gases, fuel leakage,
oil leakage, etc.
Despite the safe design of this generator,
operating this equipment imprudently, neglecting
its maintenance or being careless can cause
possible injury or death. Permit only responsible
and capable persons to operate or maintain this
equipment.
Potentially lethal voltages are generated by
these machines. Ensure all steps are taken to
render the machine safe before attempting to
work on the generator.
Parts of the generator are rotating and/or hot

PRIMEPACT 50 and 70 (50Hz) Recreational Vehicle Generators
ELECTRICAL HAZARDS
FIRE HAZARDS
• The generator covered by this manual produces
dangerous electrical voltages and can cause fatal
electrical shock. Avoid contact with bare wires, ter-
minals, connections, etc., while the unit is running.
Ensure all appropriate covers, guards and barriers
are in place before operating the generator. If you
must work around an operating unit, stand on an
insulated, dry surface to reduce shock hazard.
• Do not handle any kind of electrical device while
standing in water, while barefoot, or while hands
or feet are wet. DANGEROUS ELECTRICAL
SHOCK MAY RESULT.
• During installation onto the vehicle, properly
ground (bond) the generator either by solid mount-
ing to the vehicle frame or chassis, or by means of
an approved bonding conductor. DO NOT connect
the bonding conductor to any generator part that
might be removed or disassembled during routine
maintenance. If the grounding conductor must be
replaced, use only a flexible conductor that is of
No. 8 American Wire Gauge (AWG) copper wire
minimum.
• For fire safety, the generator must be installed and
maintained properly. Installation always must
comply with applicable codes, standards, laws and
regulations. Adhere strictly to local, state and
national electrical and building codes. Comply
with regulations the Occupational Safety and
Health Administration (OSHA) has established.
Also, ensure that the generator is installed in
accordance with the manufacturer’s instructions
and recommendations. Following proper installa-
tion, do nothing that might alter a safe installation
and render the unit in noncompliance with the
aforementioned codes, standards, laws and regu-
lations.
• Keep a fire extinguisher in the vehicle at all times.
Extinguishers rated “ABC” by the National Fire
Protection Association are appropriate for use on
the recreational vehicle generator electrical system.
Keep the extinguisher properly charged and be
familiar with its use. If you have any question per-
taining to fire extinguishers, consult your local fire
department.
• If the vehicle electrical circuits can be powered by
any other source of electricity (such as a “dock-
side” power receptacle), there must be no possibil-
ity of connecting the different power sources to the
vehicle circuits at the same time. The dockside
(utility) power source must be positively isolated
from the vehicle circuits whenever the generator is
operating. Failure to isolate the vehicle circuits
from the dockside power supply when the genera-
tor is running may result in damage to the genera-
tor or serious injury or death to dockside (utility)
power workers due to backfeed of electrical ener-
gy.
• In case of accident caused by electric shock, imme-
diately shut down the source of electrical power. If
this is not possible, attempt to free the victim from
the live conductor. AVOID DIRECT CONTACT
WITH THE VICTIM. Use a nonconducting imple-
ment, such as a rope or board, to free the victim
from the live conductor. If the victim is uncon-
scious, apply first aid and get immediate medical
help.
EXPLOSION HAZARDS
• Do not smoke around the generator. Wipe up any
fuel or oil spills immediately. Ensure that no com-
bustible materials are left in the generator com-
partment, or on or near the generator, as FIRE or
EXPLOSION may result. Keep the area surround-
ing the generator clean and free from debris.
• Gasoline is extremely FLAMMABLE and its vapors
are EXPLOSIVE. Do not permit smoking, open
flame, sparks or any source of heat in the vicinity
while handling gasoline. Comply with all laws gov-
erning the storage and handling of gasoline.
• Fuel lines must be properly installed and
fastened, and free of leaks. There must be
no possibility of gasoline vapors entering the vehi-
cle interior.
• You are required to install an approved, flexible,
nonconductive fuel line between the generator fuel
connection point and rigid fuel lines.
• Never wear jewelry when working on this equip-
ment. Jewelry can conduct electricity resulting in
electric shock, or may get caught in moving com-
ponents causing injury.

OF THE MANUAL
These Installation Instructions have been prepared
especially for the purpose of familiarizing installers
and owners of the applicable equipment with the
product's installation requirements. Give serious
consideration to all information and instructions in
the manual, both for safety and for continued reliable
operation of the equipment.
1.4 EQUIPMENT DESCRIPTION
Instructions and information in this section pertain
to Generac air-cooled generators. These generators
are designed specifically for installing in recreational
vehicles. They operate 230-volt, single-phase, 50-
Hertz, AC electrical loads that require 20.8 amps
(PP50) or 30.4 amps (PP70).
Because of the different recreational vehicle models
and the variations between the models, it would be
extremely difficult, if not impractical, to provide
detailed instructions for every possible installation.
For that reason, instructions and illustrations in this
manual are general in nature. Illustrations are not
intended to serve as detailed installation blueprints.
1.5 GENERATOR ENGINE
OPERATING SPEED
The generator’s revolving field (rotor) is driven by a
single-cylinder, four-cycle engine through a pulley and
drive belt arrangement. The generator supplies 230
volts AC at 50 Hertz when the rotor is operating at
3,000 rpm. The drive belt arrangement allows the
engine to operate at a lower speed than the rotor.
The installation should comply strictly with all
applicable codes, standards and regulations pertain-
ing to the installation and use of this product. If any
portion of this manual appears to be in conflict with
such codes, standards or regulations, the applicable
codes, standards or regulations must take prece-
dence over the manual.
1.6 GENERATOR AC
CONNECTION SYSTEM
This generator set is equipped with dual stator AC
power windings as shown in Figure 1.1. These two-
stator windings supply electrical power to customer
electrical loads by means of a dual two-wire connec-
tion system. Note, however, that the neutral is
grounded.
1.2 SAFETY

PRIMEPACT 50 and 70 (50Hz) Recreational Vehicle Generators
• Whether the generator is mounted above the hori-
2.1 LOCATION AND SUPPORT
zontal support tubing or suspended below the tub-
ing, the supporting frame used must be structural-
ly sound.
2.1.1 GENERATOR LOCATION
N
The most desirable location for the generator set is
between the vehicle's main frame members. However,
this is seldom possible. Most units must be installed
on the side of the vehicle and are difficult to reinforce.
• If the generator cannot be bolted directly to the
supporting frame or support tubing, consider
using additional tubing, angle brackets or other
supports to give the supporting frame sufficient
strength.
Many recreational vehicles have been factory
equipped with an area for the generator set. Some
vehicles may even have a generator compartment
provided by the vehicle manufacturer.
Figure 2.1 – Typical Horizontal Support Frame
Plan the generator location based on the following:
• The generator set must be installed on a frame-
work that is part of the recreational vehicle, as out-
lined in Section 2.1.2.
• The location must provide an access opening that
is large enough to permit generator removal
(unless the generator is to be removed from under-
neath the supporting framework).
• The location must provide easy access to frequent-
ly serviced components, such as filters, oil drains,
spark plugs and other common maintenance
parts.
• The location must provide sufficient room to allow
minimum clearances as outlined in Section 2.2. If
sound insulation is to be used on the compartment
walls and ceiling, the minimum recommended
applies to the space between the generator and
such insulation.
2.1.3 SUSPENDED MOUNTING
N
If you are going to suspend the generator below the
horizontal support tubing, the suspension method
you use with the vehicle frame members must (a) be
able to support the weight of the generator AND (b)
provide sufficient restraint for the generator. One typ-
ical suspended mounting system is shown in Figure
2.2. The location of a suspended mounting system
must be carefully planned, keeping the following gen-
eral rules in mind:
• The location must provide adequate cooling and
ventilating airflow for the generator without a great
deal of work and expense.
• Protect the generator against road splash and debris.
Baffles or splash guards may be required to protect
certain areas of the generator. To make sure the gen-
erator is adequately protected, road test the installa-
tion through mud, water and slush.
2.1.2 GENERATOR SUPPORT
N
The generator must be securely attached to a metal
framework that has been made part of the vehicle
frame structure by bolting or welding. The metal
framework on which the generator will rest and
which will restrain the generator set should consist of
at least two horizontal beams. These beams should
consist of (a) 1-1/2-inch square, 11-gauge steel tubing
OR (b) 1-1/2-inch, 11-gauge angle iron. A typical sup-
porting frame with horizontal support tubing, is
shown in Figure 2.1.
Figure 2.2 – Typical Suspended Mounting System
The generator can be installed so that it sits on top of
the horizontal support tubing if the vehicle design
permits. Another method is to suspend the generator
below the horizontal support tubing by means of suit-
able, structurally sound metal framework. The fol-
lowing general rules apply:
• Vehicle construction MUST be capable of support-
ing the weight of the generator.
• The installer must make certain that the selected
location will permit adequate cooling and ventilat-
ing airflow to be supplied.

2.1.4 GENERATOR RESTRAINT
2.2.2 COMPARTMENT CONSTRUCTION
N
N
Use four 3/8"-16 hardened steel bolts (Grade 5) to fas-
ten the generator to the supporting frame or the sup-
port tubing. These bolts must pass through (a) the gen-
erator mounting base, (b) the compartment floor (if a
compartment is used) and (c) the supporting frame-
work (Figure 2.3). All bolts must be long enough so that
when tight, at least three threads are visible past the
retaining lock nuts. Refer to Section 2.2 for the location
of the generator mounting holes.
• The generator compartment should be either con-
structed of, or lined with, 26-gauge galvanized
steel.
NOTE:
Aluminum is NOT an acceptable alternative to gal-
vanized steel due to aluminum’s low melting
point.
• If the compartment is lined with galvanized steel, it
may be constructed of any material. Generac rec-
ommends that the compartment be constructed of
1/2-inch thick plywood (not strandboard), with the
floor made of a double thickness of 1/2-inch ply-
wood with the grain of the wood at cross section
for added strength (Figure 2.5).
Figure 2.3 – Typical Generator Restraint
Figure 2.5 – Typical Compartment Construction
2.2 GENERATOR COMPARTMENTS
Whether the generator set is being installed inside a
compartment specifically manufactured to house a gen-
erator or inside a compartment that the installer con-
structs, the compartment MUST meet certain specifi-
cations as outlined in the following sections:
2.2.1 COMPARTMENT SIZE
N
Plan the compartment size carefully. Provide a mini-
mum clearance of 1/2 inch (13 mm) on the front and
top, 1 inch (25 mm) on the sides, and 1/2 inch (13
mm) from the back for air circulation AFTER the
compartment has been lined with metal and sound
insulation (Figure 2.4).
• If constructing a compartment, line the exterior
(underside) of the compartment floor with 26-
gauge galvanized steel.
• All seams, splices and joints of the compartment
walls (unless vapor tight by design) should be
caulked to prevent poisonous, flammable or explo-
sive vapors from entering the vehicle interior.
NOTE:
NOTE:
Refer to “Figure 1.2 – Major Features and
Dimensions” on Page 21.
Figure 2.4 – Clearances

1 1/2" Clearance on Top
Caulking must be done so that the caulking mate-
rial will stay in place permanently. Pressing such
materials as putty tape onto joints and seams is
not acceptable. A high quality silicone rubber base
sealant is recommended.

• Holes and openings made in the compartment
walls to allow for the passage of electrical conduit,
conductors, hoses, cables, etc., into the vehicle liv-
ing area must be sealed vapor tight with silicone

PRIMEPACT 50 and 70 (50Hz) Recreational Vehicle Generators
• If flexible metal conduit is used, it must be sealed
internally at the end where it terminates inside the
compartment’s electrical junction box.
NOTE:
Do not install sound insulation or any
absorbent material on the compartment floor
interior. Such materials will become soaked
with combustible or explosive vapors and liq-
uids and will become a fire hazard.
Flexible metal conduit, due to its unique con-
struction, is NOT vapor tight along its entire
length.
Using a combination of sound insulating materials
can often reduce noise more effectively than a single
material. For example, a sheet of lead or visco-elastic
material, along with a layer of other acoustical mate-
rial, is more effective than when a single material is
used.
• Seams and joints of the galvanized steel (whether
used as a liner or for the compartment itself) must
be lapped and mechanically secured. Such seams
may be manufactured, welded, bolted, riveted or
screwed. Manufactured lock seams are shown in
Figure 2.6. Installer constructed compartments
typically utilize a standard lap joint.
2.2.4 ACOUSTICS
N
Figure 2.6 – Types of Lock Seams
For additional noise abatement, the installer may
wish to consider the following:
• Using special sound insulating materials.
• Construction of
a
special noise abatement
compartment.
NOTE:
Any method used to reduce noise must not
adversely affect the flow of cooling and ventilating
air into or out of the compartment.
In addition to the effective use of sound insulating
materials, construction of a special noise abatement
compartment might be considered to reduce noise
levels. Such a compartment might be constructed as
follows (Figure 2.7):
• After the compartment has been metal lined and
vapor sealed, line the compartment interior walls
and ceiling with an approved, nonflammable
sound insulating material. See Section 2.2.3.
• Use 5/8-inch thick or 3/4-inch thick plywood in the
compartment.
• Construct the compartment floor of a double thick-
ness of 5/8-inch or 3/4-inch plywood.
• Line the compartment interior walls and floor, as
well as the underside of the floor, with 26-gauge
galvanized steel.
• Vapor seal all compartment seams and joints.
• Over the galvanized steel lining, install a combina-
tion of acoustical materials as mentioned in
Section 2.2.3.
Do not install any flammable material directly
above or around the compartment. Heat,
transferred through the compartment structure,
may be sufficient to ignite, char or discolor
seat cushions, fiberboard and other flammable
materials. You may need to use approved
nonflammable insulating materials in high
temperature areas.
2.2.3 SOUND INSULATING MATERIALS
N
To prevent fire or explosion, do not install any
insulation or other absorbent materials on the
interior or underside of the compartment floor.
Once installers have determined that a compartment
is properly constructed and metal lined, they can add
acoustical material. This may include additional
sealant or insulating material, to reflect noise away
from the vehicle interior.
• Seal all compartment door edges to prevent noise
leakage around the door perimeter.
• Line the compartment door interior (except for air
openings) with suitable, fireproof sound insulation
(such as 1-inch (25 mm) thick fiberglass with a 2-
pound density).
Sound insulating materials should be of a nonflam-
mable type. One excellent insulating material is a 1-
inch (25 mm) thick fiberglass having a 2-pound den-
sity. When fiberglass is used, its coated side should
face toward the compartment interior.

• Engine exhaust and cooling air outlets
• Generator cooling air inlet
• Four holes for passage of generator mounting
bolts. See Section 2.1.4 (Page 23).
Fuel lines and exhaust piping must not pene-
trate into the vehicle living area.

Section 2 – Installation
PRIMEPACT 50 and 70 (50Hz) Recreational Vehicle Generators
NOTE:
2.3 COOLING AND VENTILATING AIR
It is absolutely essential that an adequate flow of air
for cooling, ventilating and engine combustion be
supplied to the generator set. Without sufficient air-
flow, the engine/generator quickly overheats. Such
overheating can cause serious operating difficulties
and also may cause fire and personal injury. The
installer must make sure that sufficient air is avail-
able to the generator for cooling, ventilating and com-
bustion. The installer also must provide for a path
for exhausting the cooling air to the exterior of a com-
partment, if so equipped.
Screening, louvers or expanded metal that cover
air openings restrict airflow. You must compensate
for this by making the actual air opening propor-
tionately larger. See Section 2.3.3 (Page 27).
Figure 2.10 – Air Inlet in Compartment Door
Never use discharged cooling air for heating or
permit such air to enter the vehicle interior.
This air contains deadly carbon monoxide gas
and other poisonous, flammable or explosive
gases.
2.3.1 GENERATOR AIRFLOW
N
Engine operation drives cooling fans for the two-stage
cooling air system. A pressure fan draws cooling air
into the top of the generator (Figure 2.9). This airflow
cools the engine/generator and electronic compo-
nents. The second part of the cooling system, a suc-
tion fan, draws air that is heated from a hot engine
into a collector pan at the base of the unit. This heat-
ed air (although cooler than exhaust muffler) is then
deflected out the bottom toward the ground.
NOTE:
Be sure to meet the minimum clearances illustrat-
ed in Figure 2.4 (Page 23).
When the unit is installed on a suspended mounting
system, one of several different methods of supplying
airflow may be used as follows:
• Provide a door in the vehicle skirt having an air
inlet opening (Figure 2.11).
Figure 2.9 – Airflow Through Engine/Generator
Figure 2.11 – Suspended Mount: Inlet Door
• Using ductwork (Figure 2.12, Page 27). The
installer must be sure air is available to the top of
the generator since air inlets are located at the top.
• By providing an opening in the vehicle skirt and
space behind the generator for cooling airflow
(Figure 2.13 Page 27). Recommended clearance
behind the back of the generator is at least 1/2 inch
(13 mm).
2.3.2 COOLING AIR INLET OPENINGS
N
The minimum size of the air inlet opening, whether
the generator is housed in a conventional compart-
ment or not, is at least 100 square inches (see
Figure 2.10). This rule applies whether inlet air is
brought in through an opening in the compartment
door, an opening in the vehicle skirt, through duct-
work, or by any other means.

2.3.4 TESTING THE INSTALLATION
N
Generac recommends testing the installation to be
sure adequate cooling airflow is available to the unit
before placing the unit into service. If the unit shows
signs of overheating, you will need to enlarge the air
openings. Never place a unit into service until
absolutely certain that cooling and ventilation is ade-
quate.
NOTE:
You must test the installation, especially if you
bring in air from below the generator set.
Figure 2.13 – Air Inlet in Vehicle Skirt
2.4 GASOLINE FUEL SYSTEM
The installation of a gasoline fuel system (Figure
2.14) for a recreational vehicle generator set must
comply with applicable codes, standards and regula-
tions. The entire fuel system must be completely free
of leaks. There must be no possibility of gasoline
vapors entering the vehicle interior.

2.3.3 COMPENSATING FOR RESTRICTIONS
N
Such materials as screening, louvers or expanded
metal can restrict the free flow of air. Compensate for
this restriction by making the actual air opening pro-
portionately larger.
Fuel Filter
Fuel Line
Some materials may offer only a 60 percent “free air
inlet area.” Other more efficient materials may pro-
vide up to a 90 percent free air inlet area. The per-
centage of free air inlet opening is usually available
from the material supplier or manufacturer.
Gasoline is highly flammable, and its vapors are
explosive. Comply with all codes, standards and
regulations pertaining to gasoline fuel systems
used in recreational vehicle generators.
Properly install and maintain the fuel system
and keep it entirely free of leaks. Gasoline
vapors must not enter the vehicle interior.
To determine the actual air inlet opening size
required, divide 100 square inches by the per-
centage of free air inlet area for the material you
will use.
For example: If you plan to use screening with an 80
percent free air inlet area, divide 100 by 0.8, which
results in 125 square inches. Minimum actual size of
air inlet opening in this case is 125 square inches.
Factory installed generator fuel system components
include (a) fuel filter, (b) 12-volt DC electric pump, (c)
engine carburetor, and (d) interconnecting lines and
fittings. Connect a fuel supply line to the fuel filter
inlet. Use a flexible length of approved fuel hose
between the fuel filter inlet connection and rigid fuel
lines.

PRIMEPACT 50 and 70 (50Hz) Recreational Vehicle Generators
2.4.1 FUEL TANK
2.4.2.2 Flexible Fuel Line
N
Use an approved flexible length of fuel hose between
the generator fuel inlet connection and rigid fuel
lines. This prevents breaking of the line caused by
vibration, shifting, settling or movement. The follow-
ing rules apply:
Either the generator must share the vehicle engine's
fuel tank, or you must install a separate fuel tank for
the generator set. All fuel tanks installed on the vehi-
cle must be constructed, installed and restrained so
they comply with applicable codes, standards and
regulations.
• The flexible hose must comply with SAE J30B,
“Standard for Fuel and Oil Hose.” It must be
approved for use with gasoline.
• The hose should be at least 6 inches (152 mm)
longer than is needed to prevent the hose from
rupturing if the generator shifts or settles.
If the generator is to share the vehicle engine's tank,
separate fuel pickup tubes are required for the engine
and the generator. Generac recommends that you
make the fuel pickup tube 2 to 3 inches (51 to 76
mm) shorter than the vehicle engine's pickup tube.
This prevents the generator from depleting the entire
fuel supply during prolonged generator operating
periods.
2.5 EXHAUST SYSTEM
The generator exhaust system must be safely and
properly installed. Only approved mufflers and other
exhaust system parts must be used. A properly
installed exhaust system must be vapor tight, quiet
and completely safe.
Do NOT tee the generator fuel supply line into
the vehicle engine fuel supply line. If this is
done, the generator will be starved of fuel
when both engines are operating at the same
time. Also, while the vehicle engine is not run-
ning, generator operation may drain the vehi-
cle engine supply line, making it difficult to
start the vehicle engine.
The generator engine gives off DEADLY carbon
monoxide gas through its exhaust system. This
dangerous gas, if breathed in sufficient concen-
trations, can cause unconsciousness or even
death. Never operate the generator set with
the vehicle inside any garage or other enclosed
area. DO NOT OPERATE THE GENERATOR IF THE
EXHAUST SYSTEM IS LEAKING OR HAS BEEN
DAMAGED. SYMPTOMS OF CARBON MONOX-
IDE POISONING ARE (a) inability to think coher-
ently; (b) vomiting; (c) twitching muscles; (d)
throbbing temples; (e) dizziness; (f) headaches;
(g) weakness; and (h) sleepiness. IF YOU FEEL
ANY OF THESE SYMPTOMS, MOVE INTO FRESH
AIR IMMEDIATELY. IF SYMPTOMS PERSIST, GET
MEDICAL HELP. Do not operate the generator
until its exhaust system has been inspected and
properly repaired.
2.4.2 GENERATOR FUEL SUPPLY LINE
N
2.4.2.1 Rigid Fuel Lines
Those lines used to supply fuel from a tank to the
generator must comply with applicable codes, stan-
dards and regulations. The following general rules
apply to rigid fuel lines:
• Rigid lines should be of annealed, seamless, drawn
aluminum or steel.
• Lines and fittings must comply with SAE J512F,
“Standard Automotive Fittings,” or with ANSI
B126.26 (latest edition).
• Route the fuel line so that at least 2 inches (51 mm)
of clearance is maintained between the line and
any exhaust system parts.
Never tee the generator engine exhaust pipe
into the vehicle engine exhaust piping. This
causes excessive back pressure on the genera-
tor engine. Also, water from one engine can
damage the other engine.
• Do not attach electrical wiring to fuel lines. Route
the wiring so it cannot come into contact with any
fuel line.
• Route fuel lines so if they leak, fuel does not drip
onto any electrical or exhaust system parts.
• Use nonferrous metal straps without sharp edges
to secure fuel lines.

• If there is any possibility of the tailpipe or muffler
2.5.1 MUFFLERS AND SPARK ARRESTORS
N
being damaged, protect these damage-prone areas
by means of a protective device (such as a skid
bar).
This muffler meets code and standard requirements
of the U.S. Forest Service. Use only mufflers and
parts approved by Generac. Any person(s) installing
an unapproved muffler, or an unapproved exhaust
system part, or modifying an exhaust system in any
way that might cause a hazard, is liable for any dam-
age, injury or warranty expense that might be caused
by such unapproved installation or modification.
• Install the generator exhaust system according to
safe automotive practices.
• Use enough exhaust system hangers to prevent any
part of the system from being dislocated.
• Use exhaust system parts recommended by
Generac. Using unapproved exhaust mufflers and
exhaust system parts is the responsibility of the
person(s) installing such unauthorized parts.
• Do not terminate the exhaust system under any
opening, window or vent that can be opened or is
not permanently sealed from the vehicle interior.
• Exhaust piping must be large enough to prevent
excessive back pressure on the generator engine.
• Never tee the generator engine exhaust pipe into
the vehicle engine exhaust piping. This causes
excessive back pressure on the generator engine.
Also, water from one engine can damage the other
engine.
Failure to provide and maintain a spark arrestor may
be in violation of the law. If this generator is used on
any forest covered, brush covered or grass covered
unimproved land, you must provide a spark arrestor.
The vehicle owner or operator must maintain this
device in good condition. In the state of California,
the preceding is required by law (Section 4442 of the
California Public Resources Code). Other states may
have similar laws. Federal laws apply on federal
lands.
2.5.2 TYPE OF EXHAUST SYSTEM
N
Two types of exhaust systems for PRIMEPACT series
generators are available from Generac. They include
the following:
• Plan exhaust system installation carefully. Comply
with all applicable codes, standards and regula-
tions.
• “Out-the-bottom” exhaust system dimensions are
1 5/16” O.D., model 9742.
• “Out-the-side” exhaust system dimensions are
1” O.D., 18 gauge, modelS 9743 and 9326.
NOTE:
2.6 ELECTRICAL CONNECTIONS
Be sure to read Section 1.6 on Page 20.
The following general rules apply to electrical con-
nections in a recreational vehicle:
• Qualified electricians who are familiar with applic-
able codes, standards and regulations should
install electrical wiring.
• The wiring should comply with codes, standards
and regulations. The National Electrical Code
(NFPA 70), and state and local codes apply.
• Switches and circuit breakers should be of a type
approved for use in recreational vehicles and must
be mounted and installed to prevent damage from
road shock.
• Wiring must be of adequate size, have approved
insulative qualities and be properly supported.
• Conduit and wire openings into the generator com-
partment (if used) must be vapor-sealed to prevent
entry of flammable, explosive or poisonous gases
into the vehicle.
No matter what type of exhaust kit best fits your
recreational vehicle, the mounting base has open-
ings for either “bottom-out” or “side-out” exhaust
systems. Use the cover plate provided with the
generator to cover the opening you do NOT use.
2.5.3 EXHAUST SYSTEM SAFETY
N
• Maintain a clearance of at least 3 inches (76 mm)
between exhaust system parts and any com-
bustible material (such as wood, felt, cotton,
organic fibers or other like material). If you cannot
maintain the 3-inch (76 mm) clearance, locate,
insulate or shield the exhaust part(s) so that the
temperature of any combustible material is not
raised more than 117° F (65° C) above the ambient
air temperature.
• Extend the exhaust system at least 1 inch (25 mm)
past the outer edge of the vehicle. Do not terminate
the exhaust system under the vehicle.
• Terminate the exhaust tailpipe such that exhaust
gases will not be drawn back into the generator
compartment and recirculated.
2.6.1 ELECTRICAL JUNCTION BOX
N
Install an approved, square electrical junction box
with a blank cover on the interior or exterior wall of
the area you plan to install the generator (NOT on the
generator). Route the generator's AC output leads
into this junction box through approved flexible con-
duit. This is the point of first termination for genera-
tor AC output leads.

PRIMEPACT 50 and 70 (50Hz) Recreational Vehicle Generators
2.6.2 WIRING
N
• Wiring should be of stranded copper to reduce the
chance that vibration may cause breakage.
• Wire gauge size should be large enough to handle
at least 115 percent of the installed generator's
rated maximum current.
Do NOT connect electrical loads in excess of
any circuit breaker rating or you will develop
problems with circuit breaker tripping, which
causes a loss of AC output. Also, do NOT
exceed the generator's rated wattage capacity.
Add the watts or amperes of all lighting, appli-
ance, tool and motor loads the generator will
operate at one time. This total should be less
than the unit's rated wattage/amperage capaci-
ty.
• If neutral conductors are used, they must be the
same size as other leg wires.
• Route power supply conductors from generator AC
output leads T1 (red), T3 (black) and the green
ground wire through approved flexible conduit to
the electrical junction box on the compartment
wall.
2.6.4 CONDUIT
Route the connections between the generator and the
junction box through approved, flexible conduit. The
following general rules apply:
N
If flexible metal conduit is used between the gener-
ator and the compartment junction box, the con-
duit end that terminates the compartment junction
box must be vapor-sealed. Flexible metal conduit
is NOT vapor tight along its entire length.
• Cut wiring to the required length and allow extra
wire for junction box connections.
• Carefully prepare conduit ends to prevent sharp
edges from cutting through wiring insulation.
• Route conduit so it does not interfere with genera-
tor movement.
• If you use metallic conduit, vapor seal the end of
the conduit where it enters the junction box. Do
this because flexible metallic conduit is not vapor
proof along its entire length.
• From the junction box, route power supply wires
through approved conduit to either (a) double-
pole, double-throw transfer switch, or (b)
approved isolation receptacle. Connecting to a
transfer switch or isolation receptacle must pre-
vent vehicle electrical circuits from being connect-
ed to two different power supplies at the same time
(such as generator and dockside power).
• Conductors must be rated 221° F (105° C) or must
be of a larger conductor size.

SOURCES
Generator AC output leads T1 (red), and T3 (black)
come out of the generator as shown in Figure 2.17.
Lead T1 (red) is “hot”. There is also a green lead that
connects to ground in the junction box of the recre-
ational vehicle.
Connections from the junction box must terminate in
a double-pole, double-throw transfer switch (Figure
2.18, Page 31). An alternate method for isolating dif-
ferent power sources is by using an isolating recepta-
cle (Figure 2.19, Page 31). Whichever method you
use, you must be certain that both power sources are
NOT connected at the same time.

2.7 BATTERY INSTALLATION
2.7.1 RECOMMENDED BATTERY
N
Install a battery that meets the following require-
ments:
• The battery must be a 12-volt, automotive type
storage battery.
• For prevailing ambient temperatures above 32° F (0°
C), use a battery rated 70 amp-hours and capable of
delivering at least 400 cold-cranking amperes.
• For prevailing ambient temperatures below 32° F
(0° C), use a battery rated 95 amp-hours and capa-
ble of delivering at least 600 cold-cranking
amperes.
2.7.4 BATTERY COMPARTMENT
Install the generator battery in its own, vented com-
partment. Place the battery compartment away from
any source of heat, sparks or flame.
N
NOTE:
If the battery is to be used to power other vehicle
accessories, as well as start the generator, you may
need a battery with a larger capacity.
Provide ventilation openings in the battery compart-
ment. The minimum size of openings should be 2
square inches at the top of the compartment. Mount
the battery on a strong, rigid supporting structure,
where leaks and spills of battery fluid will not cause
damage.
2.7.2 BATTERY CABLES
N
Using battery cables that are too long or too small in
diameter may cause a drop in voltage, which causes
starting problems. For the best cold weather starting,
the voltage drop between battery terminals and the
generator connection point should not exceed 0.12
volts per 100 amperes of cranking current.
2.8 OPTIONAL ACCESSORIES
A plug-in receptacle (Figure 2.21) is provided on the
generator set, above the muffler enclosure. Use this
receptacle to connect an optional remote-mounted
start/stop panel to the generator. Installation of such
a panel will permit you to start and stop the genera-
tor engine from any convenient location inside the
vehicle.
PRIMEPACT generators are rated at about 100 DC
amperes of cranking current.
Select battery cables based on (a) cable length and (b)
prevailing ambient temperatures. Generally, the
longer the cable and the colder the weather, the larg-
er the cable size must be, as shown in the chart.

0
000
* For warm weather, use No 2 cable up to 20 feet.
2.7.3 BATTERY CABLE CONNECTIONS
N
1. Connect the battery cable from the battery post or
terminal indicated by a POSITIVE, POS or (+) to
the lug on the starter contactor (Figure 2.20).
NOTE:
Check to be sure the battery cable boot for the
starter cable has been installed.
2. Connect the battery cable from the battery post
indicated by a NEGATIVE, NEG or (-) to the
frame ground connection (Figure 2.20).
3. Connect cables so the connectors are clean
and tight.

PRIMEPACT 50 and 70 (50Hz) Recreational Vehicle Generators
3. Let the engine warm up for about five minutes to
2.8.1 REMOTE PANEL MODELS
N
allow internal temperatures to stabilize.
4. Carefully inspect the engine/generator for fuel, oil
and exhaust system leaks. Before proceeding to
the next step, correct any leakage immediately.
5. When all tests and adjustments at no-load are
completed, apply electrical loads and check for
proper operation under load. See Section 3.4.
Run the unit at least 30 minutes with loads
applied.
The remote panels mount a rocker type start/stop
switch, a “Generator Run” advisory lamp and an
hourmeter. The hourmeter should be used in con-
junction with the maintenance operations found in
Part I of this manual.
• Model 004057 includes the remote panel and a 10
foot long, 4 wire harness.
• Model 004184 includes the remote panel and a 30
foot long, 4 wire harness.
6. Turn off all electrical loads by setting the genera-
tor’s main circuit breakers to their “OFF” (or
open) position.
7. Let the unit run at no-load for a few minutes to
stabilize internal engine/-generator temperatures.
Then, shut down the engine.
3.1 POST INSTALLATION TESTS
The air-cooled generator set was factory tested and
adjusted. You should not be required to adjust the
unit any further except under special circumstances.
NOTE:
The generator set was thoroughly tested and
adjusted at the factory before shipping. No addi-
tional adjustment should be necessary. Only qual-
ified service technicians who have been trained
should perform adjustments outlined in this man-
ual.
Do not make any unnecessary adjustments.
Factory settings are correct for most applica-
tions. When making adjustments, however, be
careful to avoid overspeeding the engine.
3.2 BEFORE INITIAL START-UP
Before starting, complete the following:
3.4 TESTING UNDER LOAD
Apply electrical loads equal to about 75 to 100 per-
cent of the unit's rated wattage/amperage capacity.
1. Check the engine crankcase oil level and, if nec-
essary, fill to the dipstick “FULL” mark (cross-
hatched area) with the recommended oil. Do not
fill above the FULL mark.
2. Check the fuel supply. Gas fuel lines must have
been properly purged and leak tested in accor-
dance with applicable fuel codes. All fuel shutoff
valves in the fuel supply lines must be open.
Let the unit run at least 30 minutes with load
applied. During this part of the test, check that the
unit is not running excessively hot and that adequate
cooling airflow is available. You must not allow the
unit to overheat during prolonged operation.
NOTE:
The generator engine is equipped with a high tem-
perature switch. The switch has normally closed
(N.C.) contacts. When the engine temperature is
too high, switch contacts close, and the engine
shuts down automatically.
3.3 INITIAL START
When you are absolutely certain that the unit has
been properly installed and prepared for use, start
the engine as follows:
1. Turn off all electrical loads. Do this by setting the
generator’s main circuit breakers to their “OFF”
(or open) position.
GENERAC RECOMMENDS THAT YOU TEST THE
GENERATOR FOR ADEQUATE COOLING.
2. Refer to Part I, Section 2.5, “Starting the
Generator” (Page 8), for cranking and starting
instructions. The engine may require more
cranking for initial starting since the fuel lines
have to be primed (use of the primer switch will
shorten this time).

Section 7 – Warranty
PRIMEPACT 50 and 70 (50Hz) Recreational Vehicle Generators
CALIFORNIA AND FEDERAL EMISSION CONTROL WARRANTY STATEMENT
YOUR WARRANTY RIGHTS AND OBLIGATIONS
The California Air Resources Board (CARB) and the United States Environmental Protection Agency (EPA), together with
Generac Power Systems, Inc. (Generac), are pleased to explain the Emission Control System Warranty on your new engine.*
New utility, and lawn and garden equipment engines must be designed, built and equipped to meet stringent anti-smog stan-
dards for the state of California and the federal government. Generac will warrant the emission control system on your
engine for the periods of time listed below provided there has been no abuse, neglect, unapproved modification or improp-
er maintenance of your engine.
Your emission control system may include parts such as the carburetor, ignition and exhaust systems. Generac will repair
your engine at no cost to you for diagnosis, replacement parts and labor, should a warrantable condition occur.
MANUFACTURER’S EMISSION CONTROL SYSTEM WARRANTY COVERAGE:
Emissions control systems on 1997 and later model year engines are warranted for two years as hereinafter noted. If, dur-
ing such warranty period, any emission-related component or system on your engine is found to be defective in materials or
workmanship, repairs or replacement will be performed by a Generac Authorized Warranty Service Facility.
PURCHASER’S/OWNER’S WARRANTY RESPONSIBILITIES:
As the engine purchaser/owner, you are responsible for the completion of all required maintenance as listed in your factory
supplied Owner’s Manual. For warranty purposes, Generac recommends that you retain all receipts covering maintenance
on your engine. However, Generac cannot deny warranty solely because of the lack of receipts or for your failure to ensure
the completion of all scheduled maintenance.
As the engine purchaser/owner, you should, however, be aware that Generac may deny any and/or all warranty coverage or
responsibility if your engine, or a part/component thereof, has failed due to abuse, neglect, improper maintenance or unap-
proved modifications, or the use of counterfeit and/or ‘grey market’ parts not made, supplied or approved by Generac.
You are responsible for presenting your engine to a Generac Authorized Warranty Service Facility as soon as a prob-
lem occurs. The warranty repairs should be completed in a reasonable amount of time, not to exceed 30 days.
Warranty service can be arranged by contacting either your selling dealer or a Generac Authorized Warranty Service Facility.
To locate the Generac Authorized Warranty Service Facility nearest you, call our toll-free number:
1-800-333-1322
IMPORTANT NOTE: This warranty statement explains your rights and obligations under the Emission Control System
Warranty (ECS Warranty), which is provided to you by Generac pursuant to California and federal law. See also the “Generac
Limited Warranties for Generac Power Systems, Inc.,” which is enclosed herewith on a separate sheet, also provided to you
by Generac. The ECS Warranty applies only to the emission control system of your new engine. If there is any conflict in
terms between the ECS Warranty and the Generac Warranty, the ECS Warranty shall apply except in circumstances where
the Generac Warranty may provide a longer warranty period. Both the ECS Warranty and the Generac Warranty describe
important rights and obligations with respect to your new engine.
Warranty service can be performed only by a Generac Authorized Warranty Service Facility. When requesting warranty ser-
vice, evidence must be presented showing the date of the sale to the original purchaser/owner. The purchaser/owner shall
be responsible for any expenses or other charges incurred for service calls and/or transportation of the product to/from the
inspection or repair facilities. The purchaser/owner also shall be responsible for any and/or all damages or losses incurred
while the engine is being transported/shipped for inspection or warranty repairs.
If you have any questions regarding your warranty rights and responsibilities, you should contact Generac at the fol-
lowing address:

Section 7 – Warranty
PRIMEPACT 50 and 70 (50Hz) Recreational Vehicle Generators
EMISSION CONTROL SYSTEM WARRANTY
Emission Control System Warranty (ECS Warranty) for 1997 and later model year engines:
(a) Applicability: This warranty shall apply to 1997 and later model year engines. The ECS Warranty Period shall begin on
the date the new engine or equipment is purchased by/delivered to its original, end-use purchaser/owner and shall contin-
ue for 24 consecutive months thereafter.
(b) General Emissions Warranty Coverage: Generac warrants to the original, end-use purchaser/owner of the new engine or
equipment, and to each subsequent purchaser/owner, that each of its engines is ...
(1) Designed, built and equipped so as to conform with all applicable regulations adopted by the EPA and CARB pursuant
to their respective authority, and
(2) Free from defects in materials and workmanship which, at any time during the ECS Warranty Period, may cause a war-
ranted emissions-related part to fail to be identical in all material respects to the part as described in the engine manu-
facturer’s application for certification.
(c) The ECS Warranty only pertains to emissions-related parts on your engine, as follows:
(1) Any warranted, emissions-related parts that are not scheduled for replacement as required maintenance in the Owner’s
Manual shall be warranted for the ECS Warranty Period. If any such part fails during the ECS Warranty Period, it shall
be repaired or replaced by Generac according to Subsection (4) below. Any such part repaired or replaced under the ECS
Warranty shall be warranted for the remainder of the ECS Warranty Period.
(2) Any warranted, emissions-related part that is scheduled only for regular inspection as specified in the Owner’s Manual
shall be warranted for the ECS Warranty Period. A statement in such written instructions to the effect of “repair or replace
as necessary” shall not reduce the ECS Warranty Period. Any such part repaired or replaced under the ECS Warranty
shall be warranted for the remainder of the ECS Warranty Period.
(3) Any warranted, emissions-related part that is scheduled for replacement as required maintenance in the Owner’s
Manual shall be warranted for the period of time prior to the first scheduled replacement point for that part. If the part
fails prior to the first scheduled replacement, the part shall be repaired or replaced by Generac according to Subsection
(4) below. Any such emissions-related part repaired or replaced under the ECS Warranty shall be warranted for the
remainder of the ECS Warranty Period prior to the first scheduled replacement point for such emissions-related part.
(4) Repair or replacement of any warranted, emissions-related part under this ECS Warranty shall be performed at no
charge to the owner at a Generac Authorized Warranty Service Facility.
(5) When the engine is inspected by a Generac Authorized Warranty Service Facility, the owner shall not be held responsi-
ble for diagnostic costs if the repair is deemed warrantable.
(6) Generac shall be liable for damages to other original engine components or approved modifications proximately caused
by a failure under warranty of any emission-related part covered by the ECS Warranty.
(7) Throughout the ECS Warranty Period, Generac shall maintain a supply of warranted emission-related parts sufficient
to meet the expected demand for such emission-related parts.
(8) Any Generac authorized and approved emission-related replacement part may be used in the performance of any ECS
Warranty maintenance or repairs and will be provided without charge to the purchaser/owner. Such use shall not reduce
Generac’s ECS Warranty obligations.
(9) Unapproved, add-on, modified, counterfeit and/or ‘grey market’ parts may not be used to modify or repair a Generac
engine. Such use voids this ECS Warranty and shall be sufficient grounds for disallowing an ECS Warranty claim.
Generac shall not be held liable hereunder for failures of any warranted parts of a Generac engine caused by the use of
such an unapproved, add-on, modified, counterfeit and/or ‘grey market’ part.
