NATIONAL CODES
This product is designed and manufactured to permit
installation in accordance with National Codes. It is the
installer’s responsibility to install the product in accordance
with National Codes and/or prevailing local codes and
regulations.
PRE-INSTALLATION CHECKS
Before attempting any installation, the following points should be
considered:
• Structural strength of supporting members
• Clearances and provision for servicing
• Power supply and wiring
• Air duct connections
• Drain facilities and connections
• Location may be on any four sides of a home,
manufactured or modular, to minimize noise
CLEARANCES AND ACCESSIBILITY
The unit is designed to be located outside the building with
unobstructed condenser air inlet and discharge. Additionally,
the unit must be situated to permit access for service and
installation. 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.
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 12” clearance on all air
inlet sides. Allow 36” minimum for service access to the
compressor compartment 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 48”
clearance and provisions made to deflect the warm discharge
air out from the overhang.
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 subfreezing 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.
GROUND LEVEL PRE-INSTALLATION DETAILS
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.
MAJOR COMPONENTS
The unit includes a hermetically sealed refrigerating system
(consisting 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 reversing valve, solenoid, defrost thermostat and
control and loss of charge protection. The system is factoryevacuated, charged and performance tested. Refrigerant
amount and type are indicated on rating plate.

ROOF TOP PRE-INSTALLATION DETAILS
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.
NOTE: To ensure proper condensate drainage, unit must be
installed 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.
ROOF CURB INSTALLATIONS ONLY
NOTE: Sufficient structural support must be determined prior
to locating and mounting the curb and package unit.
Curb insulation, cant strips, flashing and general roofing
material are furnished by the contractor.
Curbing must be installed in compliance with the National
Roofing Contractors Association Manual. Construct duct work
using current industry guidelines. The duct work must be
placed into the roof curb before mounting the package unit.

CIRCULA TING AIR AND FILTERS
A
IR FLOW CONVERSION
Units can easily be converted from horizontal to down
discharge air flow delivery. In down discharge or high static
installations, the installer should measure the total external
static and review the blower performance charts before
performing the installation. In some installations it will be
necessary to change the blower speed to provide proper air
flow.
Horizontal Air Flow
Single phase models are shipped without horizontal duct
covers. If needed, these kits may be ordered through
Goodman’s Service Parts department.

Remove these panels
for downflow duct
applications
Duct Cover Installation
Down Discharge Applications
Cut insulation around bottom openings and remove panels
from the bottom of the unit, saving the screws holding the
panels in place.
NOTE: Single phase models require installation of horizontal
duct kit #20464501PDGK (medium chassis) and
#20464502PDGK (large chassis).
DUCT WORK
Duct systems and register sizes must be properly designed
for the C.F.M. and external static pressure rating of the unit.
Duct work should be designed in accordance with the
recommended methods of Air Conditioning Contractors of
America Manual D (Residential) or Manual Q (Commercial).
All duct work exposed to the outdoors must include a
weatherproof barrier and adequate insulation.
A duct system should be installed in accordance with
Standards of the National Board of Fire Underwriters for the
Installation of Air Conditioning, Warm Air Heating and
Ventilating Systems. Pamphlets No. 90A and 90B.
The supply duct from the unit through a wall may be installed
without clearance. However, minimum unit clearances as
shown in the Appendix must be maintained. The supply duct
should be provided with an access panel large enough to
inspect the air chamber downstream of the heat exchanger. A
cover should be tightly attached to prevent air leaks.
For duct flange dimensions on the unit refer to the Unit
Dimension illustration in the Appendix.
For down discharge applications, the duct work should be
attached to the roof curb prior to installing the unit. Duct work
dimensions are shown in the roof curb installation manual.
If desired, supply and return duct connections to the unit may
be made with flexible connections to reduce possible unit
operating sound transmission.
FILTERS
Filters are not provided with unit and must be supplied and
externally installed in the return duct system by the installer . A
field-installed filter grille is recommended for easy and
convenient access to the filters for periodic inspection and
cleaning. When installing filters, ensure the air flow arrows
on the filter are pointing toward the circulator blower.

STARTUP, ADJUSTMENTS, AND CHECKS
COOLING START-UP PROCEDURES
With power turned off at all disconnects:
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.
3. Turn on the electrical supply at the disconnect.
4. Turn the fan switch to the “ON” position. The blower should
begin ramping up immediately.
5. Turn the fan switch to “AUTO” position. The blower should
begin ramping down after an approximate 60-second
delay.
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.
7. Turn the temperature setting to the highest position,
stopping the unit. The indoor blower will continue to run
for approximately 60-seconds.
8. Turn the thermostat system switch to “OFF” and disconnect
all power when servicing the unit.
HEAT PUMP START-UP PROCEDURE
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. Af ter the cooling mode is checked
out, turn the thermostat system switch to “OFF”.
2. Turn the thermostat system switch to “HEA T” and fan switch
to “AUTO”.
3. Slowly raise the heating temperature setting. When the
heating first stage makes contact, stop raising the
temperature setting.. The compressor, blower and fan
should now be running with the reversing valve in the deenergized (heating) position. After giving the unit time to
settle out, make sure the unit is supplying heated air.
4. If the outdoor ambient is above 80°F, the unit may trip on
its high pressure cut out when on heating. The compressor
should stop. The heating cycle must be thoroughly
checked, so postpone the test to another day when
conditions are more suitable. DO NOT FAIL TO TEST.
5. If the outdoor ambient is low and the unit operates properly
on the heating cycle, you may check the pressure cutout
operation by blocking off the indoor return air until the unit
trips.
6. If unit operates properly in the heating cycle, raise the
temperature setting until the heating second stage makes
contact. Supplemental resistance heat, if installed should
now come on. Ensure all heaters energize.
NOTE: *PH1542-60 have two stages of compressor heat.
During resistance heat test, increase temperature setting
until third stage heat is energized.
If outdoor thermostats are installed, the outdoor ambient
must be below the set point of these thermostats for the
heaters to operate. It may be necessary to jumper these
thermostats to check heater operation if outdoor ambient
is mild.
7. THERMOSTA TS WITH EMERGENCY HEA T . For thermostats
with an emergency heat switch, raise the temperature
setting until the heating second stage makes contact. The
emergency heat switch is located at the bottom of the
thermostat. Move the switch to emergency heat. The heat
pump will stop, the blower will continue to run, all heaters
will come on and the thermostat emergency heat light will
come on.
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.
FINAL SYSTEM CHECKS
1. Ensure all supply and return air grilles are adjusted and
the air distribution system is balanced for the best
compromise between heating and cooling.
2. Ensure there are no air leaks in the duct work.
3. Check air flow and refrigerant charge. See Sections on
Air Flow Measurement and Adjustment and Checking
Charge.
4. Ensure the unit is free of “rattles”, and the tubing in the unit
is free from excessive vibration. The tubes or lines should
not rub against sheet metal surfaces, edges or each other.
5. Ensure the Owner is instructed on the unit operation, filter,
servicing, correct thermostat operation, etc.
Set the thermostat at the appropriate setting for cooling and
heating or automatic changeover for normal use.
NOTE: The “Cooling Start-up Procedure” is a recommended
step as it serves as an system indicator that the unit will operate
normally.
COMPONENTS
Contactor
This control is activated (closed) by the room thermostat for
both heating and cooling. The contactor has a 24V coil and
supplies power to the compressor and outdoor fan motor.

This control is activated by the thermostat (24V coil) and
supplies power to the contactor.
Defrost Control
The Defrost Control provides time/temperature initiation and
termination of the defrost cycle. When a defrost cycle is
initiated, the Defrost Control shifts the reversing valve to
“COOLING” mode, stops the outdoor fan and brings on
supplemental heat. Normally, a defrost cycle will take only 23 minutes unless system is low on refrigerant charge or
outdoor conditions are severe (i.e. windy and cold). The defrost
control also provides for a 3 minute off cycle compressor
delay.
Outdoor Thermostat
These optional controls are used to prevent full electric heater
operation at varying outdoor ambient (0°F to 45°F). They are
normally open above their set points and closed below to
permit staging of indoor supplement heater operation. If the
outdoor ambient temperature is below 0°F (-18°C) with 50%
or higher RH, an outdoor thermostat (OT) must be installed
and set at (0°) on the dial. Failure to comply with this
requirement may result in damage to the product which may
not be covered by the manufacturer’s warranty.
Reversing Valve Coil
This coil is activated by the thermostat, in the cooling mode
and during defrost. It positions the reversing valve pilot valve
for cooling operation.
Indoor Blower Motor
This is activated by the room thermostat by COOLING or FAN
ON position. For GPC/GPH models, the motor is energized
directly by the room thermostat for X-13 motors. X-13 motors
are constant torque motors with very low power consumption.
For APH models, the motor is energized by the fan control
board for ECM motors. ECM motors are constant CFM motors
with very low power consumption. This motor is energized by
a 24V signal from the thermostat. (See Air Flow Measurement
and Adjustment for speed adjustment instructions).
The following figures show a schematic of a heat pump on
the cooling 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 reverse 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 supplementary
heat for all heat pump installations in areas where the
temperature drops below 45°F. It is also a good practice to
provide sufficient supplementary heat to handle the entire
heating 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 reversing 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.
HEAT PUMP OPERATION
C
OOLING CYCLE
When the heat pump is in the cooling cycle, it operates exactly
as a Air Conditioner unit.
HEATING CYCLE
The heat pump operates in the heating cycle by redirecting
refrigerant flow through the refrigerant circuit external to the
compressor. 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.

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 34°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 remains closed. When
the sensor opens (approximately 60°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.

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.
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.
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.

AIR FLOW MEASUREMENT AND ADJUSTMENT
Please review the Duct Work section before proceeding
with the airflow measurements and adjustments in this
section.
Unit blower curves (see Specification Sheets) are based on
external static pressure (ESP per in/W .C.). The duct openings
on the unit are considered internal static pressure. 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 pilot tubes or a Magnahelic
gauge and confirm CFM to blower curves in the Specification
Sheets.
NOTE: Never run CFM below 350 CFM per ton, evaporator
freezing or poor unit performance is possible.
AIR FLOW ADJUSTMENTS FOR INDOOR BLOWER MOTOR
X-13 Motor
Adjust the CFM by changing the 24V low voltage lead at the
speed terminal block on the motor. (T1-Low Speed, T2 and
T3-Medium Speed, T4 and T5-High Speed).
NOTE: Factory set T1 (G , fan), T2 (cool/Hi cool), T3 (W2 electric
heat), T4 and T5 reserved for high static (cool/Hi cool) and
W2. GPH1548M41 and GPH1560M41 low cool Y1 will run at G
speed.
ECM Motor
The ECM control board is factory set with the dip switch #4 in
the “ON” position for single stage units and to the "OFF"
position for the 2 stage units. All other dip switches are factory
set in the “OFF” position. For most applications, the settings
are to be changed according to the electric heat size.
The ECM motor provides many features not available on the
traditional PSC motor. These features include:
• Improved Efficiency
• Constant CFM
• Soft Start and Stop
• Improved Humidity Control
ECM Motor Speed Adjustment
Each ECM blower motor has been preprogrammed for
operation at 4 distinct air flow levels when operating in Cooling/
Heat Pump mode or Electric Heat mode. These 4 distinct
levels may also be adjusted slightly lower or higher if desired.
The adjustment between levels and the trim adjustments are
made by changing the dip switch(s) either to an "OFF" or "ON"
position.
APH DIP SWITCH FUNCTIONS
The ECM motor has an electronic control that contains eight
(8) 2-position dip switches. The function of these dip switches
is shown in Table 1.

APH HUMIDITY CONTROL
When using a Humidistat (normally closed), cut jumper PJ6 on the
control board. The Humidistat will only affect both low stage and
high stage cooling air flow by adjusting the Air flow to 85%.
APH TWO-STAGE HEATING
When using staged electric heat, cut jumper PJ4 on the control
board.
APH THERMOSTAT WIRING
Use thermostat wiring diagrams provided with the thermostat
when making these connections.
See Appendix for Blower Performance tables.
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

EXPANSION VALVE (TXV) SYSTEM
Single Speed Application (*PH1524/43 and GPC15)
1. Purge gauge lines. Connect service gauge manifold to
access fittings. Run system at least 10 minutes to allow
pressure to stabilize.
2. Temporarily install thermometer on liquid (small) line near
liquid line access fitting with adequate contact and insulate
for best possible reading.
3. Check subcooling and superheat. Systems with TXV
application should have a subcooling of 10 + 2°F and
superheat of 15 to 18ºF.
a. If subcooling and superheat are low, adjust TXV to 15
- 18ºF then check subcooling.
b. If subcooling is low and superheat is high, add charge
to raise subcooling to 10 ± 2ºF then check superheat.
c. If subcooling and superheat are high, adjust TXV valve
to 15 - 18ºF then check subcooling.
d. If subcooling is high and superheat is low, adjust TXV
valve to 15 to 18ºF superheat and remove charge to
lower the subcooling to 10 ± 2ºF.
The TXV should NOT be adjusted at light load conditions 55º
to 60ºF, under such conditions only the subcooling can be
evaluated. This is because suction pressure is dependent
on indoor air flow, and wet bulb temperature.
NOTE: Do NOT adjust charge based on suction pressure
unless there is a gross undercharge.
4. Disconnect manifold set. Installation is complete.
Two Speed Application (*PH1549/60)
Run the unit on low stage cooling for 10 minutes until
refrigerant pressures stabilize. Follow the guidelines and
methods below to check unit operation and ensure that the
refrigerant charge is within limits. Charge the unit on low
stage.
1. Purge gauge lines. Connect service gauge manifold to
access fittings. Run system at least 10 minutes to allow
pressure to stabilize.
2. Temporarily install thermometer on liquid (small) line near
liquid line access fitting with adequate contact and insulate
for best possible reading.
3. Check subcooling and superheat. Two stage systems
running on low stage with TXV application should have a
subcooling of 5 to 7 ºF and superheat of 15 to 18ºF.
a. If subcooling and superheat are low, adjust TXV to 15
to 18ºF superheat, then check subcooling.
NOTE: To adjust superheat, turn the valve stem
clockwise to increase and counter clockwise to
decrease.
b. If subcooling is low and superheat is high, add charge
to raise subcooling to 5 to 7 ºF then check superheat.
c. If subcooling and superheat are high, adjust TXV valve
to 15 to 18ºF superheat, then check subcooling.
d. If subcooling is high and superheat is low, adjust TXV
valve to 15 to 18ºF superheat and remove charge to
lower the subcooling to 5 to 7 ºF.
NOTE: Do NOT adjust the charge based on suction
pressure unless there is a gross undercharge.
4. Disconnect manifold set, installation is complete.
Refrigerant Charge Check (Units with Fixed Orifice Devices)
After completing airflow measurements and adjustments the
unit’s refrigerant charge must be checked. The unit comes
factory charged, but this charge is based on 325 CFM per ton
and minimum ESP per ARI test conditions (generally between
.15 -.25 ESP). When air quantity or ESP is different than above,
the refrigerant charge must be adjusted to the proper amount.
All package units with fixed orifice devices are charged using
the super heat method at the compressor suction line.
For charging in the warmer months, 8 ± 3ºF superheat at the
compressor is required at conditions 95ºF outdoor ambient
(dry bulb temperature), 80ºF dry bulb / 67ºF wet bulb indoor
ambient, approximately 50% humidity. This superheat varies
when conditions vary from the conditions described.
13
Page 14
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.
HEAT PUMP - HEATING CYCLE
The proper method of charging a heat pump in the heat mode is by weighing the charge according to the total charge listed on the
rating plate.
ELECTRICAL ADJUSTMENTS
This series of electric cooling and, heat pump package equipment is designed to accept a field installed electric heat kit. The unit
is equipped to easily install the HKR Series Electric Heat Kit. Full Installation Instructions are included in this kit. Please use this
document for guidance in field equipping the package unit with electric heat.
Choose the heat kit that fits the application for the specific installation. Permanently mark the unit’s nameplate with the model
being installed. High and low voltage connections are detailed in the heat kit instructions.
Indoor Blower motor speed tap selection may need to be modified to accommodate normal continuous operation to prevent a
nuisance trip. See tables below.

MAINTENANCE
The Self Contained Package Air 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 air flow 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 (see Appendix) should
help in identifying problems if the unit does not operate
properly.
Refer to Blower Performance section in the Appendix - Higher
air flow lowers temperature rise.
Lower air flow raises temperature rise.
SERVICE
THE FOLLOWING INFORMA TION IS FOR USE BY
QUALIFIED SERVICE AGENCY ONLY : OTHERS SHOULD
NOT A TTEMPT TO SERVICE THIS EQUIPMENT .
COMMON CAUSES OF UNSATISFACTORY OPERATION OF HEAT
PUMP ON THE HEATING CYCLE
INADEQUATE AIR VOLUME THROUGH INDOOR COIL
When a heat pump is in the heating cycle, the indoor coil is functioning 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.
OUTSIDE AIR INTO RETURN DUCT
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 cycling resulting in low heating output. It may also cause false defrosting.
UNDERCHARGE
An undercharged heat pump on the heating cycle will cause low
discharge pressure resulting in low suction pressure and frost
accumulation on the outdoor coil.
POOR “TERMINATING” SENSOR CONTACT
The unit’s defrost terminating sensor must make good thermal
contact with the outdoor coil tubing. Poor contact may not terminate the unit’s defrost cycle quickly enough to prevent the unit from
cutting out on high discharge pressure.
MALFUNCTIONING REVERSING VALVE - THIS MAY BE DUE TO:
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
voltage, check wiring circuit.
3. Valve will not shif t:
a. Undercharged - check for leaks;
b. Valve Body Damaged - Replace valve;
c. Unit Properly Charged - If it is on the heating cycle,
raise the discharge pressure by restricting air flow
through the indoor coil. If the valve does not shift, tap it
lightly on both ends with a screwdriver handle. DO NOT
T AP THE V ALVE BODY. If the unit is on the cooling cycle,
raise the discharge pressure by restricting air flow
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.
