Allow 18” minimum for service access to the compressor com-
partment and controls. The top of the unit should be completely
unobstructed. If units are to be located under an overhang, there
should be a minimum of 36” clearance and provisions made to
deflect the warm discharge air out from the overhang.
The information on the rating plate is in compliance with the FTC
& DOE rating for single phase units. The three phase units in
this series are not covered under the DOE certified program. The
efficiency ratings of these units are a product of thermal effi-
ciency determined under continuous operating conditions inde-
pendent of any installed system.
UNIT LOCATION
Consider the affect of outdoor fan noise on conditioned space and
any adjacent occupied space. It is recommended that the unit be
placed so that condenser air discharge does not blow toward
windows less than 25 feet away. Consideration should also be
given to shade and unit appearance.
Heat pumps require special location consideration in areas of heavy
snow accumulation and/or areas with prolonged continuous sub-
freezing temperatures. Heat pump unit bases have holes under the
outdoor coil to permit drainage of defrost water accumulation. The
unit must be situated to permit free unobstructed drainage of the
defrost water and ice. A minimum 2" clearance under the outdoor
coil is required in the milder climates.

FINES. BECAUSE REGULATIONS MAY VARY DUE TO PASSAGE OF
NEW LAWS, WE SUGGEST A CERTIFIED TECHNICIAN PERFORM ANY
WORK DONE ON THIS UNIT. SHOULD YOU HAVE ANY QUESTIONS
PLEASE CONTACT THE LOCAL OFFICE OF THE EPA.
GROUND LEVEL PRE-INSTALLATION DETAILS
NATIONAL CODES
The unit should be set on a solid, level foundation - preferably a
concrete slab at least 4 inches thick. The slab should be above
ground level and surrounded by a graveled area for good drainage.
Any slab used as a unit’s foundation should not adjoin the building
as it is possible that sound and vibration may be transmitted to the
structure.
This product is designed and manufactured to permit installation
in accordance with National Codes. It is the installer’s responsi-
bility to install the product in accordance with National Codes and/
or prevailing local codes and regulations.
MAJOR COMPONENTS
The unit includes a hermetically sealed refrigerating system (con-
sisting of a compressor, condenser coil, evaporator coil with
flowrator), an indoor blower, a condenser fan and all necessary
internal electrical wiring. The heat pump also includes a revers-
ing valve, solenoid, defrost thermostat and control and loss of
charge protection. The system is factory-evacuated, charged and
performance tested. Refrigerant amount and type are indicated
on rating plate.
PRE-INSTALLATION CHECKS
Before attempting any installation, the following points should
be considered:
•
•
•
•

ROOF TOP PRE-INSTALLATION DETAILS
CLEARANCES AND ACCESSIBILITY
Ensure that the roof is weather tight and allows proper drainage of
condensation. Use steel or treated wood beams as unit support
for load distribution.
The unit is designed to be located outside the building with un-
obstructed condenser air inlet and discharge. Additionally, the
unit must be situated to permit access for service and installa-
tion. Condenser air enters from three sides. Air discharges
upward from the top of the unit. Refrigerant gauge connections
are made on the right side of the unit as you face the compressor
compartment. Electrical connections can be made either on the
right, bottom or duct panel side of the unit. The best and most
common application is for the unit to be located 10” from wall (4”
minimum) with the connection side facing the wall. This “close
to the wall” application minimizes exposed wiring.
NOTE: To ensure proper condensate drainage, unit must be in-
stalled in a level position.
•
To avoid possible property damage or personal injury, the
roof must have sufficient structural strength to carry the
weight of the unit(s) and snow or water loads as required
by local codes. Consult a structural engineer to determine
the weight capabilities of the roof.
•
•
The unit may be installed directly on wood floors or on
Class A, Class B, or Class C roof covering material.
To avoid possible personal injury, a safe, flat surface for
service personnel should be provided.
Close to the wall application assures free, unobstructed air to
the other two sides. In more confined application spaces, such
as corners provide a minimum 10” clearance on all air inlet sides.

1. Turn thermostat system switch to “COOL” and fan switch
to “AUTO”. Next, turn the temperature setting as high as it
will go.
2. Inspect all registers and set them to the normal open
position.
8. If checking the unit in the wintertime, when the outdoor coil
is cold enough to actuate the defrost control, observe at
least one defrost cycle to make sure the unit defrosts
completely.
3. Turn on the electrical supply at the disconnect.
4. Turn the fan switch to the “ON” position. The blower should
operate after a 7-second delay.
5. Turn the fan switch to “AUTO” position. The blower should
stop after a 65-second delay.
FINAL SYSTEM CHECKS
1. Check to see if all supply and return air grilles are adjusted
and the air distribution system is balanced for the best
compromise between heating and cooling.
6. Slowly lower the cooling temperature until the unit starts.
The compressor, blower and fan should now be operating.
Allow the unit to run 10 minutes, make sure cool air is being
supplied by the unit.
2. Check for air leaks in the ductwork.
7. Turn the temperature setting to the highest position,
stopping the unit. The indoor blower will continue to run for
65-seconds.
3. See Sections on Air Flow Measurement and Adjustment
and Checking Charge.

8. Turn the thermostat system switch to “OFF” and disconnect
all power when servicing the unit.
HEAT PUMP START-UP PROCEDURE
5. Set the thermostat at the appropriate setting for cooling
and heating or automatic changeover for normal use.
1. Check the cooling mode for the heat pump in the same
manner as above. The reversing valve is energized when
the thermostat is placed in the cooling position. A clicking
sound should be noticeable from the reversing valve. By
lowering the temperature setting to call for cooling, the
contractor is energized. The compressor, blower and fan
should then be running. After the cooling mode is checked
out, turn the thermostat system switch to “OFF”.
6. Be sure the Owner is instructed on the unit operation,
filter, servicing, correct thermostat operation, etc.

Crankcase Heater
HEATING CYCLE
This item is “ON” whenever power is supplied to the unit and the
crankcase heater thermostat is closed. Crankcase heater
thermostat closes at 67° and opens at 85°. It warms the compressor
crankcase thereby preventing liquid migration and subsequent
compressor damage. The insert type heater is self regulating. It is
connected electrically to the contactor L1 and L2 terminals.
The heat pump operates in the heating cycle by redirecting refrig-
erant flow through the refrigerant circuit external to the compres-
sor. This is accomplished with through the reversing valve. Hot
discharge vapor from the compressor is directed to the indoor coil
(evaporator on the cooling cycle) where the heat is removed, and
the vapor condenses to liquid. It then goes through the expansion
device to the outdoor coil (condenser on the cooling cycle) where
the liquid is evaporated, and the vapor goes to the compressor.

When the solenoid valve coil is operated either from heating to
cooling or vice versa, the piston in the reversing valve to the low
pressure (high pressure) reverse positions in the reversing valve.
The following figures show a schematic of a heat pump on the cool-
ing cycle and the heating cycle. In addition to a reversing valve, a
heat pump is equipped with an expansion device and check valve
for the indoor coil, and similar equipment for the outdoor coil. It is
also provided with a defrost control system.
The expansion devices are flowrator distributors and perform the
same function on the heating cycle as on the cooling cycle. The
flowrator distributors also act as check valves to allow for the re-
verse of refrigerant flow.
When the heat pump is on the heating cycle, the outdoor coil is
functioning as an evaporator. The temperature of the refrigerant in
the outdoor coil must be below the temperature of the outdoor air
in order to extract heat from the air. Thus, the greater the difference
in the outdoor temperature and the outdoor coil temperature, the
greater the heating capacity of the heat pump. This phenomenon
is a characteristic of a heat pump. It is a good practice to provide

requirement should there be a component failure of the heat pump,
such as a compressor, or refrigerant leak, etc.
Since the temperature of the refrigerant in the outdoor coil on the
heating cycle is generally below freezing point, frost forms on the
surfaces of the outdoor coil under certain weather conditions of
temperature and relative humidity. Therefore, it is necessary to
reverse the flow of the refrigerant to provide hot gas in the outdoor
coil to melt the frost accumulation. This is accomplished by re-
versing the heat pump to the cooling cycle. At the same time, the
outdoor fan stops to hasten the temperature rise of the outdoor
coil and lessen the time required for defrosting. The indoor blower
continues to run and the supplementary heaters are energized.
4. Disconnect outdoor fan by removing the outdoor fan motor
wire from “DF2” on defrost control.
5. Restart unit and allow frost to accumulate.
6. After a few minutes of operation, the unit’s defrost
thermostat should close. To verify this, check for 24 volts
between “DFT” and “C” on board. If the temperature at the
thermostat is less than 28° F and the thermostat is open,
replace the unit’s defrost thermostat, as it is defective.
7. When the unit’s defrost thermostat has closed, short the
test pins on the defrost board until the reversing valve
shifts, indicating defrost. This should take up to 21
seconds depending on what timing period the control is
set on. After defrost initiation, the short must instantly be
removed or the unit’s defrost period will only last 2.3
seconds.
8. The control is shipped from the factory with the compressor
delay option selected. This will de-energize the
compressor contactor for 30 seconds on defrost initiation
and defrost termination. If the jumper is set to Normal, the
compressor will continue to run during defrost initiation
and defrost termination. The control will also ignore the
low pressure switch connected to R-PS1 and PS2 for 5
minutes upon defrost initiation and 5 minutes after defrost
termination.
DEFROST CONTROL
During operation the power to the circuit board is controlled by a
temperature sensor, which is clamped to a feeder tube entering
the outdoor coil. Defrost timing periods of 30,60 and 90 minutes
may be selected by setting the circuit board jumper to 30, 60 and
90 respectively. Accumulation of time for the timing period selected
starts when the sensor closes (approximately 31° F), and when
the wall thermostat calls for heat. At the end of the timing period,
the unit’s defrost cycle will be initiated provided the sensor re-
mains closed. When the sensor opens (approximately 75° F), the
defrost cycle is terminated and the timing period is reset. If the
defrost cycle is not terminated due to the sensor temperature, a
twelve minute override interrupts the unit’s defrost period.
9. After the unit’s defrost thermostat has terminated, check
the defrost thermostat for 24 volts between “DFT” and “C”.
The reading should indicate 0 volts (open sensor).
10.Shut off power to unit.
11. Replace outdoor fan motor lead to terminal “DF2” on defrost
board and turn on power.
AIRFLOW MEASUREMENT AND ADJUSTMENT
After reviewing Duct Work section, proceed with airflow measure-
ments and adjustments. The unit blower curves (see Specifica-
tion Sheets) are based on external static pressure (ESP per in/wc).
The duct openings on the unit are considered internal static pres-
sure. As long as ESP is maintained, the unit will deliver the proper
air up to the maximum static pressure listed for the CFM required
by the application (i.e. home, building, etc.)
In general, 400 CFM per ton of cooling capacity is a rule of thumb.
Some applications depending on the sensible and latent capacity
requirements may need only 350 CFM or up to 425 CFM per ton.
Check condition space load requirements (from load calculations)
and equipment expanded ratings data to match CFM and capacity.
After unit is set and duct work completed, verify the ESP with a
1-inch inclined manometer with pitot tubes or a Magnahelic gauge
and confirm CFM to blower curves in the Specification Sheets. All
units have three-speed blower motors. If low speed is not utilized,
the speed tap can be changed to medium or high speed.
NOTE: Never run CFM below 350 CFM per ton, evaporator freezing
or poor unit performance is possible.
SUGGESTED FIELD TESTING/TROUBLE SHOOTING
1. Run unit in the heating mode (room thermostat calling for
heat).
2. Check unit for proper charge. Note: Bands of frost on the
condenser coil indicate low refrigerant charge.
3. Shut off power to unit.

REFRIGERANT CHARGE CHECKS
After completing airflow measurements and adjustments, the unit’s
refrigerant charge must be checked. The unit is factory charged
based on 400 CFM per ton at minimum ESP per AHRI test condi-
tions (generally between .15 - .25 ESP). When air quantity or ESP
is differs from this, charge must be readjusted to the proper amount.
All package units are charged to the superheat method at the
compressor suction line (these are fixed orifice devices).
For charging in the warmer months, 8 +/-3ºF superheat at the com-
pressor is required at conditions: 95ºF outdoor ambient (dry bulb
temperature), 80ºF dry bulb / 67ºF wet bulb indoor ambient, ap-
proximately 50% humidity. This superheat varies when conditions
vary from the conditions described.

SYSTEMSUPERHEAT
A superheat charge chart is available for other operating condi-
tions. Use it to provide the correct superheat at the conditions the
unit is being charged at.
After superheat is adjusted it is recommended to check unit sub-
cooling at the condenser coil liquid line out. In most operating
conditions 10 - 15ºF of sub-cooling is adequate.
SUPERHEAT CAN BE DETERMINED AS FOLLOWS:
1. Read suction pressure. Determine Saturated Suction
Temperature from tables or pressure gauge saturated
temperature scale (R-410A).
2. Read suction line temperature.
3. Use the following formula:
SUPERHEAT = SUCTION LINE TEMP - SAT. SUCTION TEMP

Do not introduce cold outside air into the return duct of a heat
pump installation. Do not allow air entering the indoor coil to drop
below 65° F. Air below this temperature will cause low discharge
pressure, thus low suction pressure, and excessive defrost cy-
cling resulting in low heating output. It may also cause false de-
frosting.

1. Solenoid not energized - In order to determine if the
solenoid is energized, touch the nut that holds the solenoid
cover in place with a screwdriver. If the nut magnetically
holds the screwdriver, the solenoid is energized and the
unit is in the cooling cycle.
2. No voltage at unit’s solenoid - Check unit voltage. If no

3. Valve will not shift:
WARNING
HIGH VOLTAGE!
DISCONNECT ALL POWER BEFORE SERVICING OR INSTALLING
THIS UNIT. MULTIPLE POWER SOURCES MAY BE PRESENT. FAILURE
TO DO SO MAY CAUSE PROPERTY DAMAGE, PERSONAL INJURY OR
DEATH.
a. Undercharged - check for leaks;
b. Valve Body Damaged - Replace valve;
The Self Contained PackageAir Conditioner and Heat Pump should
operate for many years without excessive service calls if the unit is
installed properly. However it is recommended that the homeowner
inspect the unit before a seasonal start up. The coils should be
free of debris so adequate airflow is achieved. The return and
supply registers should be free of any obstructions. The filters
should be cleaned or replaced. These few steps will help to keep
the product up time to a maximum. The Troubleshooting Chart
(on page 11) should help in identifying problems if the unit does
not operate properly.
c. Unit Properly Charged - If it is on the heating cycle,
raise the discharge pressure by restricting airflow
through the indoor coil. If the valve does not shift, tap it
lightly on both ends with a screwdriver handle. DO NOT
TAP THE VALVE BODY. If the unit is on the cooling cycle,
raise the discharge pressure by restricting airflow
through the outdoor coil. If the valve does not shift after
the above attempts, cut the unit off and wait until the
discharge and suction pressure equalize, and repeat
above steps. If the valve does not shift, replace it.

INADEQUATE AIR VOLUME THROUGH INDOOR COIL
When a heat pump is in the heating cycle, the indoor coil is func-
tioning as a condenser. The return air filter must always be clean,
and sufficient air volume must pass through the indoor coil to
prevent excessive discharge pressure, and high pressure cut out.
