IMPORTANT SAFETY INSTRUCTIONS
Liquid-cooled 30 kW Generators
• Inspect the generator regularly, and promptly repair • Generators installed with an automatic transfer
or replace all worn, damaged or defective parts using
switch will crank and start automatically when NOR-
MAL (UTILITY) source voltage is removed or is below
an acceptable preset level. To prevent such automatic
start-up and possible injury to personnel, disable
the generator’s automatic start circuit (disconnect
battery cables, etc.) before working on or around the
unit. Then, place a “Do Not Operate” tag on the gen-
erator control panel and on the transfer switch.
• 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 implement, such
as a dry rope or board, to free the victim from the live
conductor. If the victim is unconscious, apply first aid
and get immediate medical help.
only factory-approved parts.
• Before performing any maintenance on the generator,
disconnect its battery cables to prevent accidental
start-up. Disconnect the cable from the battery 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 conditions from
leaking exhaust gases, fuel leakage, oil leakage, etc.
ELECTRICAL HAZARDS
• All generators covered by this manual produce dan-
gerous electrical voltages and can cause fatal electri-
cal shock. Utility power delivers extremely high and
dangerous voltages to the transfer switch as well as
the standby generator. Avoid contact with bare wires,
terminals, connections, etc., on the generator as well
as the transfer switch, if applicable. Ensure all appro-
priate covers, guards and barriers are in place before
operating the generator. If work must be done around
an operating unit, stand on an insulated, dry surface
to reduce shock hazard.
• Never wear jewelry when working on this equipment.
Jewelry can conduct electricity resulting in electric
shock, or may get caught in moving components
causing injury.
FIRE HAZARDS
• Keep a fire extinguisher near the generator at all
times. Do NOT use any carbon tetra-chloride type
extinguisher. Its fumes are toxic, and the liquid can
deteriorate wiring insulation. Keep the extinguisher
properly charged and be familiar with its use. If there
are any questions pertaining to fire extinguishers,
consult the local fire department.
• 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.
• If people must stand on metal or concrete while
installing, operating, servicing, adjusting or repair-
ing this equipment, place insulative mats over a dry
wooden platform. Work on the equipment only while
standing on such insulative mats.
• The National Electrical Code (NEC), Article 250
requires the frame and external electrically conduc-
tive parts of the generator to be connected to an
approved earth ground and/or grounding rods. This
grounding will help prevent dangerous electrical
shock that might be caused by a ground fault condi-
tion in the generator set or by static electricity. Never
disconnect the ground wire.
• Wire gauge sizes of electrical wiring, cables and cord
sets must be adequate to handle the maximum elec-
trical current (ampacity) to which they will be sub-
jected.
• Before installing or servicing this (and related) equip-
ment, make sure that all power voltage supplies are
positively turned off at their source. Failure to do so
will result in hazardous and possibly fatal electrical
shock.
• Connecting this unit to an electrical system normally
supplied by an electric utility shall be by means of a
transfer switch so as to isolate the generator electric
system from the electric utility distribution system
when the generator is operating. Failure to isolate the
two electric system power sources from each other
by such means will result in damage to the generator
and may also result in injury or death to utility power
workers due to backfeed of electrical energy.
EXPLOSION HAZARDS
• Properly ventilate any room or building housing the
generator to prevent build-up of explosive gas.
• Do not smoke around the generator. Wipe up any fuel
or oil spills immediately. Ensure that no combustible
materials are left in the generator compartment, or
on or near the generator, as FIRE or EXPLOSION
may result. Keep the area surrounding the generator
clean and free from debris.
• These generator sets may operate using one of
several types of fuels. All fuel types are potentially
FLAMMABLE and/or EXPLOSIVE and should be
handled with care. Comply with all laws regulating
the storage and handling of fuels. Inspect the unit’s
fuel system frequently and correct any leaks imme-
diately. Fuel supply lines must be properly installed,
purged and leak tested according to applicable fuel-
gas codes before placing this equipment into service.
• Diesel fuels are highly FLAMMABLE. Gaseous fluids
such as natural gas and liquid propane (LP) gas are
extremely EXPLOSIVE. Natural gas is lighter than air,
and LP gas is heavier than air; install leak detectors
accordingly.

Section 1 - General Information
Liquid-cooled 30 kW Generators
1.1 GENERATOR
1.3 AUTOMATIC SYSTEM OPERATION
When this generator, along with a transfer switch, has
been installed and interconnected, a circuit board
in the generator panel constantly monitors UTILITY
power source voltage. Should that voltage drop below
a preset value, and remain at such a low state for
a preset amount of time, the generator cranks and
starts. After the generator starts, the transfer switch
transfers load circuits so the generator can power
them.
This equipment is a liquid-cooled, engine-driven
generator set. The generator is designed to supply
electrical power that operates critical electrical loads
during utility power failure. The unit has been facto-
ry-installed in a weather resistant, all metal enclosure
and is intended for outdoor installation only. Use
this generator as a source of electrical power for the
operation of 120 and/or 240VAC, single-phase loads.
When UTILITY source voltage has been restored, the
switch re-transfers back to the UTILITY source volt-
age and the generator then shuts down.
If this generator is used to power electrical load
circuits normally powered by a UTILITY power
source, it is required by code to install a trans-
fer switch. The transfer switch must effectively
isolate the electric system from the utility distri-
bution system when the generator is operating
(NEC 701). Failure to isolate an electrical system
by such means results in damage to the genera-
tor and may also result in injury or even death
to utility power workers due to backfeed of
electrical energy.
Please reference the transfer switch manual for spe-
cific information.
1.4 GENERATOR AC CONNECTION
SYSTEMS
The generator was shipped from the factory with its
stator AC output leads connected in a single-phase,
three-wire generator AC connection system (Figure
1.1). The stator assembly in this system consists of
a pair of stationary windings, with two leads brought
out of each winding. Each single winding can sup-
ply 120VAC, 60 Hertz. When the two windings are
connected in series, a 240VAC, 60 Hertz AC output
results. Typically the two HOT leads in the circuit
are wires 11 and 44. The NEUTRAL leads are the
junction of Wires 22 and 33. The NEUTRAL is not
grounded.
1.2 TRANSFER SWITCH
This generator system may include a matched auto-
matic transfer switch which is intended to be used
in conjunction with the generator. It is supplied in
a NEMA 3R enclosure. The NEMA 3R enclosure is
weather proof and can be used indoors or outdoors.
Follow these rules:
• Install the transfer switch on a firm, sturdy sup-
porting structure.
Figure 1.1 - Generator AC Connection System
• To prevent switch distortion, level the switch if
necessary. This can be done by placing washers
between the switch enclosure and the mounting
surface.
• Never install the switch where water or any corro-
sive substance might drip onto the enclosure.
• Protect the switch at all times against excessive
moisture, dust, dirt, lint, construction grit and cor-
rosive vapors.
If a transfer switch is not included, one may be pur-
chased separately from an Authorized Dealer.
1.5 MAIN CIRCUIT BREAKER
The generator’s main circuit breaker is included with
the unit as shipped from the factory. The breaker for
each unit is described in Figure 1.2.

Figure 1.4 - Low Oil Pressure Switch
1.6 GENERATOR FUEL SYSTEM
The unit has been factory tested and adjusted using a
natural gas fuel system. If propane (LP) gas is neces-
sary, contact an authorized service dealer.
Fuel pressure for a natural gas set up should be five
inches to 14 inches of water column (0.18 to 0.5
psi) at all load ranges.
Fuel pressure for an LP vapor set up should be 11
inches to 14 inches of water column (0.4 to 0.5
psi) at all load ranges.
NOTE:
A seperate gas line and regulator may be needed
to assure proper gas pressure to the generator.
Improper gas pressure can cause hard starting and
affect engine durability.
NOTE:
The Low Oil Pressure, High Coolant Temperature
and Low Coolant Level are not monitored for the
first 10 seconds of engine run time.
Gaseous fuels such as natural and LP (propane)
‹
1.7.2 HIGH COOLANT TEMPERATURE
SWITCH
gas are highly explosive. Even the slightest
spark can ignite such fuels and cause an explo-
sion. No leakage of fuel is permitted. Natural
gas, which is lighter than air, tends to collect in
high areas. LP gas is heavier than air and tends
to settle in low areas.
This normally open (N.O.) thermostatic switch has
sensing tip which is immersed in captive coolant.
Should coolant temperature exceed about 230°F
(110°C), the switch contacts close. This causes the
engine to shut down automatically and turns on
the high coolant temperature/low coolant level LED
(Figure 1.5).
1.7 ENGINE PROTECTIVE DEVICES
The engine has several safety switches which cause
the engine to automatically shut down under the
following conditions: low oil pressure, high coolant
temperature, engine overspeed, low coolant level or
overcrank (Figure 1.3).

1.7.3 LOW COOLANT LEVEL SWITCH
Should engine coolant level drop below the level of
the high coolant temperature switch, it is possible for
the engine to overheat without automatic shutdown.
To prevent such overheating without automatic shut
down, the engine has a low coolant level sensor. If the
engine coolant drops too low, the engine automatical-
ly shuts down and turns on the high coolant tempera-
ture/low coolant level LED (Figure 1.6 on page 6).
‹
1.7.1 LOW OIL PRESSURE SWITCH
This switch is normally-closed (N.C.) but is held open
by engine oil pressure during engine running. Should
operating oil pressure drop below about 8-10 psi (55-
68 kPa), the switch contacts close, the engine shuts
down automatically, and the low oil pressure LED is
turned ON (Figure 1.4).

‹
1.7.7 LOW BATTERY
The engine control board continually monitors the
battery voltage and turns on the low battery LED
if the battery voltage falls below 11.0 VDC for one
minute. Low battery voltage is a non-latching alarm,
which will automatically clear if the battery voltage
rises above 11.0 VDC.
The control system will not attempt to start the
engine if there is a low battery condition, however, if
the engine is already running when the low battery
condition occurs, the engine will continue to run as
long as possible.
Battery voltage is NOT monitored during the crank
cycle.
‹
1.7.4 OVERSPEED SHUTDOWN
‹
1.7.8 ALARM RESET
The engine control board receives AC frequency sig-
nals from an engine run winding in the alternator.
Should AC frequency exceed about 72 Hertz for three
seconds or 75 Hertz instantaniously, the engine shuts
down and the overspeed LED turns on. Should AC
frequency exceed about 72 Hertz, circuit board action
will automatically shutdown the engine (Figure 1.7).
If the engine control board shuts down the genera-
tor for any of the above reasons, the engine remains
stopped until the alarm is cleared by placing the
AUTO/OFF/MANUAL switch into the OFF position.
‹
1.7.9 DC FUSES
These fuses are located on the front panel of the con-
trol system. They protect the panel wiring and com-
ponents from damaging overload. Always remove the
15 amp main fuse before working on the generator.
The unit will not start or crank if this fuse is blown.
Replace the fuse with one of the same size, type, and
rating (main AGC-15, battery charger AG4).

1.7.5 RPM SENSOR LOSS
After unpacking, carefully inspect the generator for
any damage that may have occurred during ship-
ment. If loss or damage is noted at the time of deliv-
ery, have the person(s) making delivery note all dam-
age on the freight bill or affix their signature under
the consignor’s memo of loss or damage.
If the engine control board does not receive a proper
rpm signal from the starter during cranking or run-
ning, it shuts down the engine on rpm sensor loss
and flash the overspeed LED.
‹
1.7.6 OVERCRANK SHUTDOWN
1.9 LIFTING THE GENERATOR
The engine control board uses a cyclic cranking pro-
cess when attempting to start the engine. The first
crank cycle is a 15-second crank followed by a seven-
second rest. This is followed by five more crank
cycles each with a seven-second crank followed by a
seven-second rest.
When lifting or hoisting equipment is used, be
careful not to touch overhead power lines. The
generators weight of more than 900 pounds
requires proper tools, equipment, and qualified
personnel to be used in all phases of handling
and unpacking.
If the engine fails to start after all six attempts, the
start attempt is stopped and the overcrank LED’s
illuminated.

This generator can be installed in conjunction with
an engineered “GTS” type transfer switch, if neces-
sary.
1.14 ENGINE OIL RECOMMENDATIONS
The unit has been filled with 5W-20 engine oil at the
factory. Use a high-quality detergent oil classified “For
Service CC, SD, SE, SF.” Detergent oils keep the engine
cleaner and reduce carbon deposits. Use oil having
the following SAE viscosity rating, based on the ambi-
ent temperature range anticipated before the next oil
change:
The standard transfer switch has no sensing or con-
trolling circuit boards. Instead, the generator control
console houses a “Printed Circuit Board Assembly”,
which controls all phases of operation, including
engine start up and load transfer.

by means of a transfer switch, so as to isolate
the electric system from the utility distribution
system when the generator is operating. Failure
to isolate the electric system by these means
will result in damage to the generator and may
also result in injury or death to utility workers
due to backfeed of electrical energy.
Any attempt to crank or start the engine before it
has been properly serviced with the recommend-
ed oil may result in an engine failure.
If an open bottom is used, the engine-generator
is to be installed over non-combustible materi-
als and should be located such that combustible
materials are not capable of accumulating under
the generator set.
1.15 COOLANT RECOMMENDATIONS
Use a mixture of half low silicate ethylene glycol base
anti-freeze and half de-ionized water. Cooling system
capacity is about 12 U.S. quarts (11.4 liters). Use only
de-ionized water and only low silicate anti-freeze. If
desired, add a high quality rust inhibitor to the rec-
ommended coolant mixture. When adding coolant,
always add the recommended 50-50 mixture.
Only qualified, competent installation contractors
or electricians thoroughly familiar with applicable
codes, standards and regulations should install this
standby electric power system. The installation must
comply strictly with all codes, standards and regula-
tions pertaining to the installation.
Do not use any chromate base rust inhibitor
with ethylene glycol base anti-freeze or chro-
miumhydroxide (“green slime”) forms and will
cause overheating. Engines that have been oper-
ated with a chromate base rust inhibitor must
be chemically cleaned before adding ethylene
glycol base anti-freeze. Using any high silicate
anti-freeze boosters or additives will also cause
overheating. It is also recommend that any solu-
ble oil inhibitor is NOT USED for this equipment.
After the system has been installed, do nothing
that might render the installation in noncompli-
ance with such codes, standards and regulations.

Install the generator set, in its protective enclosure
outdoors, where adequate cooling and ventilating air
always is available. Consider these factors:
• Install the unit where air inlet and outlet open-
ings will not become obstructed by leaves, grass,
snow, etc. If prevailing winds will cause blowing or
drifting, consider using a windbreak to protect the
unit.
• Install the generator on high ground where water
levels will not rise and endanger it.
• This genset must be installed on a level surface.
The base frame must be level within 1/2 inch all
around.
• Allow sufficient room on all sides of the generator
for maintenance and servicing. A good rule is to
allow five feet of space on all sides.

Figure 2.2 – Generator Grounding Lug (typical)
2.5 EMERGENCY CIRCUIT ISOLATION
METHOD
This prevents overloading the generator by keeping
electrical loads below the wattage/amperage capacity
of the generator. If the generator can only power criti-
cal loads, within it’s wattage/amperage capacity, dur-
ing utility power outages, use the emergency circuit
isolation method.
GROUNDING
LUG
Critical electrical loads are grouped together and
wired into a separate “Emergency Distribution Panel.”
Load circuits powered by that panel are within the
wattage/amperage capacity of the generator set. The
transfer switch must meet the following require-
ments:
DANGER
• It must have an ampere rating equal to the total
amperage rating of the emergency distribution
panel circuit.
• Have it installed between the building’s main dis-
tribution panel and the emergency distribution
panel.
Do not connect the ground wire to any pipe
that carries a flammable or explosive substance
– FIRE or an EXPLOSION may result.
Proper grounding helps protect personnel against
electrical shock in the event of a ground fault condi-
tion in the generator or in connected electrical devic-
es. In addition, grounding helps dissipate static elec-
tricity that often builds up in ungrounded devices.
2.6 TOTAL CIRCUIT ISOLATION
METHOD
When a generator capable of powering all electrical
loads in the circuit is to be installed, use the “Total
Circuit Isolation Method.” It is possible for the gen-
erator to be overloaded when this isolation method is
employed. The following apply to the transfer switch
in this type of system.
2.8 GENERATOR AC NEUTRAL
CONNECTIONS
The manufacturer uses an UNGROUNDED AC neu-
tral. Grounding is recommended only at the main
service entrance. If the neutral wire is grounded and
one of the phase loads becomes grounded, the exces-
sive current opens the load circuit breaker or col-
lapses the generator field. The actual result depends
on the electrical characteristics of the particular
installed generator.
• Ampere rating of the transfer switch must equal
the ampere rating of the normal incoming utility
service.
• The transfer switch is installed between the util-
ity service entrance and the building distribution
panel.
2.7 GROUNDING THE GENERATOR
The National Electrical Code requires the frame and
external electrically conductive parts of this equip-
ment to be properly connected to an approved earth
ground and/or grounding rods. For that purpose, a
GROUND LUG (Figure 2.2) is provided on the gen-
erator mounting base. Consult a qualified electrician
for grounding requirements in the area. Grounding
procedures must meet local regulations.
Failure to connect the generator neutral proper-
ly will result in unbalanced line-to-neutral volt-
ages. Resulting high voltages will cause equip-
ment damage.
2.9 TRANSFER SWITCH SIGNAL
CONNECTIONS
‹
2.9.1 PRE-PACKAGED ATS
If the generator is to be installed with a pre-packaged
(non-control board based) transfer switch, it is nec-
essary to connect the control wires to the generator
and set position two of the four-position dip switch
to OFF.
Setting switch two to OFF allows the control PCB to
perform the ATS control functions.

Control system interconnections consist of N1 and
N2, and leads 23 and 194. Control system intercon-
nection leads must be run in a conduit that is sepa-
rate from the AC power lead. Recommended wire
gauge sizes for this wiring depends on the length of
the wire, as recommended below:
Battery electrolyte fluid is an extremely caus-
tic sulfuric acid solution that can cause severe
burns. Do not permit fluid to contact eyes, skin,
clothing, painted surfaces, etc. Wear protective
goggles, protective clothing and gloves when
handling a battery. If fluid is spilled, flush the
affected area immediately with clear water.
MAXIMUM WIRE LENGTH
RECOMMENDED WIRE
SIZE
Spilled electrolyte is to be washed down with
an acid neutralizing agent. A common practice
is to use a solution of one pound (500 grams)
bicarbonate of soda to one gallon (4 liters) of
water. The bicarbonate 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.

2.9.2 GTS-TYPE ATS
If the generator is to be installed with an automatic
transfer switch, such as an engineered GTS-type
switch, it is necessary to connect the two-wire start
control system.
Do not dispose of the battery in a fire. The
battery is capable of exploding.
Connect the two-wire start signal from the automatic
transfer switch to the automatic start connection,
which is located in the middle, on the bottom, inside
the control panel. Match wires 178 and 183 in the
transfer switch to 178 and 183 on the terminal strip
in the control panel. The conductors for the two-
wire start circuit must be in their own conduit. (See
Section 3.1 for further explanation.)
Do not open or mutilate the battery. Released
electrolyte can be toxic and harmful to the skin
and eyes.
The battery represents a risk of high short circuit
current. When working on the battery, always
remove watches, rings or other metal objects,
and only use tools that have insulated handles.
When replacing batteries, use the same number
and type of battery. The recommended batteries are
Group 26, 12V negative ground 525 CCA/75 AH mini-
mum capacity, or Group 27F, 12V negative ground
600 CCA/90 AH minimum capacity. All batteries
must be at 100 percent state-of-charge before they
are installed on the generator.
2.10 BATTERY INSTALLATION
DANGER
Standby generators installed with automatic
transfer switches will crank and start automati-
cally when NORMAL (UTILITY) source voltage is
removed or is below an acceptable preset level.
To prevent such automatic start-up and possible
injury to personnel, ensure that the 15A and
4A fuses are removed from the control console,
the AUTO/OFF/MANUAL switch is set to OFF,
and the utility supply to the battery charger is
removed before removing or connecting battery
cables.
When using maintenance-free batteries, it is not
necessary to check the specific gravity or electrolyte
level. Have these procedures performed at the inter-
vals specified in Section 4, “Maintenance.” A nega-
tive ground system is used. Battery connections are
shown on the wiring diagrams. Make sure all batter-
ies are correctly connected and terminals are tight.
Observe battery polarity when connecting batteries to
the generator set.
Storage batteries give off explosive hydrogen
gas. This gas can form an explosive mixture
NOTE:
around the battery for several hours after charg-
ing. The slightest spark can ignite the gas and
cause an explosion. Such an explosion can shat-
ter the battery and cause blindness or other
injury. Any area that houses a storage battery
must be properly ventilated. Do not allow smok-
ing, open flame, sparks or any spark producing
tools or equipment near the battery.
Damage will result if the battery connections are
made in reverse.
2.11 PREPARATION BEFORE START-UP
The instructions in this section assume that the
standby generator has been properly installed, ser-
viced, tested, adjusted and otherwise prepared for
use by a competent, qualified installation contractor.
Be sure to read the “Safety Rules” on Pages 2 and 3,
as well as all other safety information in this manual,
before attempting to operate this (and related) equip-
ment.

2.11.1 PRIOR TO INITIAL START-UP
‹
2.11.6 BELT TENSION
Check-the engine-fan belt tension and condition prior
to placing the unit into service and at recommended
intervals. Belt tension is correct when a force of
approximately 22 pounds (10 kg), applied midway
between pulleys, deflects the belt about 3/8- to 5/8-
inch (10 to 16 mm).
Prior to initially starting the generator, it must
be properly prepared for use. Any attempt to
crank or start the engine before it has been
properly serviced with the recommended types
and quantities of engine fluids (oil, coolant, fuel,
etc.) may result in an engine failure.
‹
2.11.7 ELECTRICAL SYSTEM
Before starting the generator for the first time, the
installer must complete the following procedures. For
follow-up maintenance information and/or service
intervals, please refer to Section 4, “Maintenance.”
Make sure the generator is properly connected to an
approved earth ground and/or ground rod.
Make sure the generator battery is fully charged,
properly installed and interconnected, and ready for
use.
‹
2.11.2 TRANSFER SWITCH
Check to ensure that there are no loose electrical con-
nections. Restrain any loose wires to keep them clear
of any moving generator set components.
If this generator is used to supply power to any elec-
trical system normally powered by an electric utility,
the National Electrical Code requires that a transfer
switch be installed. The transfer switch prevents elec-
trical backfeed between two different electrical sys-
tems (for additional information, see the applicable
transfer switch manual for this unit). The transfer
switch, as well as the generator and other standby
components, must be properly located and mounted
in strict compliance with applicable codes, standards
and regulations.
3.1 USING AN ENGINEERED “GTS”
TRANSFER SWITCH
When required, the pre-packaged standby generator
can be installed with an engineered “GTS” type auto-
matic transfer switch.
In this application, the GTS is responsible for utility
sensing, weekly exercising, and load transferring.
‹
2.11.3 FUEL SYSTEM
Position two of the four-position dip switch is used to
turn over this control to the GTS.
Make sure the fuel supply system to the generator (a)
delivers the correct fuel at the correct pressure and (b)
is properly purged and leak tested according to code.
No fuel leakage is permitted. See “Specifications”
(Section 1.10) for more information.

2.11.4 GENERATOR SET LUBRICATION
Check the engine crankcase oil level before operating
and add oil to the proper level – the dipstick “FULL”
mark. Never operate the engine with the oil level
below the dipstick “ADD” mark. See “Specifications”
(Section 1.10) and “Engine Oil Recommendations”
(Section 1.14).
• The control board will NOT activate the transfer
output.
• The control board WILL monitor all engine condi-
tions and shut down on all the faults listed in this
document.
Pos2 OFF — ATS Application
NOTE:
• The generator’s control board will perform all of
the automatic features listed in this document.
• The two-wire start connections should NOT be
used.
This engine is shipped from the manufacturer
with 5W-20 oil. This oil should be changed after
30 hours of operation.
‹
2.11.5 ENGINE COOLANT
GTS Mode Operation
When in GTS mode, the generator’s control board
will respond as follows based on the AUTO/OFF/
MANUAL switch position.
Have the engine cooling system properly filled with
the recommended coolant mixture. Check the system

ADJUSTMENTS
3.5 RETRANSFER AND SHUTDOWN
When utility power source voltage has been restored,
electrical loads may be transferred back to that
source and the generator can be shut down as fol-
lows:
Engine speed governing is also controlled by the
engine control board. Connector J2 on the engine
control board interfaces with a governor driver mod-
ule and the Bosch throttle body. The engine gover-
nor has been set by the factory during final testing
of the generator and, in most cases, should not be
adjusted.
• Verify that UTILITY power supply voltage to the
transfer switch has been positively turned OFF,
using whatever means provided (such as utility
main line circuit breaker).
If, however, adjustments are necessary, or a new
engine control board is installed in the generator, the
following procedure should be followed (Figure 3.2):
• Set the generator’s main circuit breaker to its OFF
or OPEN position.
1. Set all three potentiometers (pots) fully counter-
clockwise.
2. Under no load condition, increase the GAIN pot
as much as possible without causing instability.
3. Apply 1/4, 1/2, 3/4 and full load to the unit.
Decrease the GAIN pot if there is instability at any
load point.
4. Under full load condition, increase the stability
pot until the unit returns to 60 Hertz (or 50 Hertz
in 50 Hertz applications).
5. Reduce load to 3/4, 1/2, 1/4 and no load. Decrease
the stability pot if there is instability at any load
point.
6. Adjust differential pot to make the recovery to
load changes even faster and minimize load
change undershoot and overshoot. If it is set too
high it may introduce oscillations at some load.
It can be set to zero (full CCW) if a small amount
causes oscillations at some load.
• Let the generator engine run at no-load for a few
minutes, to stabilize internal unit temperatures.
• On the generator console, set the AUTO/OFF/
MANUAL switch to OFF. Wait for engine to come to
a complete stop.
• For transfer to utility position, refer to the Owner’s
Manual of the particular transfer switch.
• Turn on the UTILITY power supply to the transfer
switch, using whatever means provided (such as
a utility main line circuit breaker). The UTILITY
power source now powers the loads.
3.6 AUTOMATIC OPERATION
To set the system for fully automatic operation, pro-
ceed as follows:
• Check that load circuits are connected to the
utility power supply.
• Set the AUTO/OFF/MANUAL switch to its AUTO
position.
• Set the generator main circuit breaker to its ON or
CLOSED position.

4.5.9 INSPECT ENGINE GOVERNOR
Visually inspect electronic governor.
DANGER
Do not attempt to adjust the governor. Only
qualified service facilities should adjust the
governor. Excessively high operating speeds
are dangerous and increase the risk of personal
injury. Low speeds impose a heavy load on the
engine when adequate engine power is not
available and may shorten engine life. Correct
rated frequency and voltage are supplied only
at the proper governed speed. Some connected
electrical load devices may be damaged by incor-
rect frequency and/or voltage. Only qualified
service technicians should adjust the governed
speed.
After refilling the crankcase with oil, always
check oil level on dipstick. NEVER OPERATE
ENGINE WITH OIL BELOW THE DIPSTICK “ADD”
MARK.

4.6.2 BATTERY
All lead-acid storage batteries discharge when not in
use. Refer to specific instructions and warnings that
accompany the battery. If such information is not
available, observe the following precautions when
handling a battery:
• DO NOT use jumper cables and a booster battery
to crank or start the generator engine.
3. Check the spark plug gap using a wire feeler
gauge. Adjust the gap to 1.06-1.16 mm (0.042-
0.046 inch) by carefully bending the ground elec-
trode (Figure 4.4).
• DO NOT recharge a weak battery while it is
installed in the generator. Remove battery from
generator and recharge in a well-ventilated area,
away from fuel vapors, sparks, heat or flames.
• Battery electrolyte fluid is an extremely caustic
sulfuric solution that can cause severe burns. DO
NOT permit fluid to contact eyes, skin, clothing,
painted surfaces, wiring insulation, etc. If any bat-
tery fluid is spilled, flush the affected area with
clear water immediately.
Figure 4.4 – Setting the Spark Plug Gap
SET PLUG GAP AT 1.06-1.16 mm
(0.042-0.046 inch)
• Always wear safety glasses, rubber apron and
gloves when handling a battery.
• Batteries give off explosive hydrogen gas while
charging. The gas can form an explosive mixture
around the battery for several hours after charging.
Any spark, heat or flames can ignite the gas and
cause an explosion which can shatter the battery,
causing blindness or other serious injury.

4.5.13 COOLANT CHANGE
‹
4.6.3 BATTERY MAINTENANCE
Everyyear,haveAuthorizedServiceFacilitydrain,flush
and refill the cooling system. See SPECIFICATIONS
(Section 1.10) for cooling system recommendations.
The battery should be inspected per the “Service
Schedule,” Section 6. The following procedure should
be followed for inspection:
1. Inspect the battery posts and cables for tightness
and corrosion. Tighten and clean as necessary.
2. Check the battery fluid level of unsealed batteries
and, if necessary, fill with DISTILLED WATER
ONLY. DO NOT USE TAP WATER IN BATTER-
IES.
3. Have the state of charge and condition checked.
This should be done with an automotive-type bat-
tery hydrometer.
4.6 MISCELLANEOUS MAINTENANCE
‹
4.6.1 CLEANING THE GENERATOR
Keep the generator as clean and as dry as possible.
Dirt and moisture that accumulates on internal gen-
erator windings have an adverse effect on insulation
resistance.
Periodically clean generator exterior surfaces. A soft
brush may be used to loosen caked on dirt. Use a
vacuum system or dry, low pressure air to remove
any accumulations of dirt. The generator is housed
inside an all-weather enclosure, clean the enclosure
with a soft, damp cloth or sponge and water.
Once each year, have the generator cleaned and
inspected by an Authorized Service Dealer. That
dealer will use dry, low pressure air to clean internal
windings. Parts inside the control console should be
cleaned and inspected at this time as well.

4.6.4 BATTERY REPLACEMENT
DANGER
When replacing batteries, use the same number and
the type of battery that follows:
Storage batteries give off explosive hydrogen
gas. This gas can form an explosive mixture
around the battery for several hours after charg-
ing. The slightest spark can ignite the gas and
cause an explosion. Such an explosion can shat-
ter the battery and cause blindness or other
injury. Any area that houses a storage battery
must be properly ventilated. Do not allow smok-
ing, open flame, sparks or any spark producing
tools or equipment near the battery.

Spilled electrolyte is to be washed down with
an acid neutralizing agent. A common practice
is to use a solution of one pound (500 grams)
bicarbonate of soda to one gallon (4 liters) of
water. The bicarbonate 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.
Do not use any jumper cables or booster battery
to crank and start the generator engine. If the
battery has completely discharged, remove it
from the generator for recharging.
Ensure that the 15A and 4A fuses are removed
from the control console, the AUTO/OFF/
MANUAL switch is set to OFF, and the utility
supply to the battery charger is removed before
removing or connecting battery cables. If the
switch is set to AUTO or MANUAL, the genera-
tor can crank and start as soon as the battery
cables are connected.
Be sure the UTILITY power supply to the battery
charger is turned off, or sparking may occur at
the battery posts as the cables are attached and
cause an explosion.

Section 10 – Warranty
Liquid-cooled 30 kW Generators
®
GENERAC POWER SYSTEMS "TWO YEAR" LIMITED WARRANTY FOR GUARDIAN
"PREPACKAGED EMERGENCY AUTOMATIC STANDBY GENERATORS"
For a period of two years from the date of original sale, Generac Power Systems, Inc. (Generac) warrants that its Guardian generator will
be free from defects in material and workmanship for the items and period set forth below. Generac will, at its option, repair or replace
any part which, upon examination, inspection and testing by Generac or a Guardian Authorized Warranty Service Dealer, is found to
be defective. Any equipment that the purchaser/owner claims to be defective must be examined by the nearest Guardian Authorized
Warranty Service Dealer. All transportation costs under the warranty, including return to the factory, are to be borne and prepaid by
the purchaser/owner. This warranty applies only to Generac Guardian prepackaged emergency automatic standby generators sold and
rated for use in "Standby" applications.
WARRANTY SCHEDULE
YEARS ONE and TWO - 100% (one hundred percent) transferable coverage on Labor and Part(s) listed (proof of purchase and main-
tenance is required):
Engine - All Components
Alternator - All Components
Transfer System - All Components
Steel enclosures are warranted against rusting for the first year of ownership only. Damage caused after receipt of generator is the
responsibility of the owner and is not covered by this warranty. Nicks, scrapes, dents or scratches to the painted enclosure should be
repaired promptly by the owner.
All warranty expense allowances are subject to the conditions defined in Guardian's Warranty Policies, Procedures and Flat Rate
Manual.
THIS WARRANTY SHALL NOT APPLY TO THE FOLLOWING:
• Guardian generators that utilize non-Guardian/Generac replacement parts.
• Guardian generators utilizing non-Guardian/Generac automatic transfer switches.
• Repairs or diagnostics performed by individuals other than Guardian/Generac authorized dealers not authorized in writing by
Generac Power Systems.
• Any Guardian generators used as rental or trailer mounted applications.
• Units used for prime power in place of existing utility power where utility power is present or in place of utility power where utility
power service does not normally exist.
• Costs of normal maintenance, adjustments, installation and start-up.
• Steel enclosures that are rusting due to the improper installation, location in a harsh or saltwater environment or scratched where
integrity of paint applied is compromised.
• Failures caused by any contaminated fuels, oils, coolants or lack of proper fluid amounts.
• Failures due, but not limited, to normal wear and tear, accident, misuse, abuse, negligence or improper installation. As with all
mechanical devices, the Generac engines need periodic part(s) service and replacement to perform well. This warranty will not
cover repair when normal use has exhausted the life of a part(s) or engine.
• Failures caused by any external cause or act of God, such as collision, theft, vandalism, riot or wars, nuclear holocaust, fire,
freezing, lightning, earthquake, windstorm, hail, volcanic eruption, water or flood, tornado or hurricane.
• Damage related to rodent and/or insect infestation.
• Products that are modified or altered in a manner not authorized by Generac in writing.
• Any incidental, consequential or indirect damages caused by defects in materials or workmanship, or any delay in repair or
replacement of the defective part(s).
• Failure due to misapplication.
• Telephone, cellular phone, facsimile, internet access or other communication expenses.
• Living or travel expenses of person(s) performing service, except as specifically included within the terms of a specific unit warranty
period.
• Expenses related to "customer instruction" or troubleshooting where no manufacturing defect is found.
• Rental equipment used while warranty repairs are being performed.
• Costs incurred for equipment used for removal and/or reinstallation of generator, (i.e.; cranes, hoists, lifts, etc.)
• Overnight freight costs for replacement part(s).
• Overtime labor.
• Starting batteries, fuses, light bulbs and engine fluids.
THIS WARRANTY IS IN PLACE OF ALL OTHER WARRANTIES, EXPRESSED OR IMPLIED. SPECIFICALLY, GENERAC MAKES
NO OTHER WARRANTIES AS TO THE MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. Some states do not
allow limitations on how long an implied warranty lasts, so the above limitation may not apply to you.
GENERAC'S ONLY LIABILITY SHALL BE THE REPAIR OR REPLACEMENT OF PART(S) AS STATED ABOVE. IN NO EVENT
SHALL GENERAC BE LIABLE FOR ANY INCIDENTAL OR CONSEQUENTIAL DAMAGES, EVEN IF SUCH DAMAGES ARE A
DIRECT RESULT OF GENERAC'S NEGLIGENCE. Some states do not allow the exclusion or limitation of incidental or consequential
damages, so the above limitation may not apply to you.
This warranty gives you specific legal rights. You also have other rights from state to state.
