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.
MAJOR COMPONENTS
GENERAL
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 factory- evacuated, charged and
performance tested. Refrigerant amount and type are indicated on rating plate.
INSTALLATION
PRE-INSTALLATION CHECKPOINTS
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
CLEARANCE
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 or left
sides 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
10″ clearance on all air inlet sides. Allow 18″ 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 36″ clearance and provisions made to deflect the warm
discharge air out from the overhang.
LocaTtion
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.
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. For rooftop installation, steel
or treated wood beams should be used as unit support for load distribution.
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.
OuTsIDE SLAB INSTALLATION (FIGURE 1)
- The unit must be mounted on a solid, level foundation.
- Select a location that will minimize the length of the supply and return ducts.
- Select a location where external water drainage cannot collect around the unit.
- Consideration should also be given to shade, appearance and noise.
ROOFTOP INSTALLATION (FIGURE 2)
- Before locating the unit on the roof, make sure that the strength of the roof and beams is adequate to support the weight involved. (See specification sheet for weight of units.) This is very important and the installer’s responsibility.
- Make proper consideration for the weather—tight integrity of the roof and proper drainage of condensate.
- To ensure proper condensate drainage, unit must be installed in a level position.
- Consideration should also be given to shade, appearance and noise.
WARNING
DO NOT, UNDER ANY GIRCUMSTANGES, GONNECT RETURN DUGTWORK TO ANY OTHER HEAT
PRODUCING DEVIGES SUCH AS A FIREPLACE INSERT, STOVE, ETC. UNAUTHORIZED USE OF
SUGH DEVICES MAY RESULT IN PROPERTY DAMAGE, FIRE, CARBON MONOXIDE POISONING,
EXPLOSION, PERSONAL INJURY OR DEATH.
DUCTING
Ducting work should be fabricated by the installing contractor in accordance
with local codes. Industry manuals may be used as a guide when sizing and
designing the duct system- such as NESCA (National Environmental Systems
Contractors Association, 1501 Wilson Blvd., Arlington, Virginia 22209).
The unit should be placed as close as possible to the space to be air-
conditioned allowing clearance dimensions as indicated. Ducts should run as
directly as possible to supply and retum outlets. Use of non-flammable
weatherproof flexible connectors on both supply and retum connections at the
unit to reduce noise transmission is recommended.
Itis preferable to install the unit on the roof of the structure if the
registers or diffusers are located in the wall or ceiling. A slab installation
is recommended when the registers are low on the wall or in the floor.
CONNECTING THE RETURN AND SuppLY FLEXIBLE DucT IN MANUFACTURED OR MoDULAR
HOUSING APPLICATION The return and supply fittings are to be attached at the
unit to a suitable square to round duct converter. Your distributor has a
factory designed square to round converter transition. The model #s of these
kits are as follows: Small Chassis 275″ SQRPCH102, Large and Extra Large
Chassis 32.5.” and 36” SQRPCH103 (See Specification Sheets for Dimension
details). The SQRPCH101 has 14” duct collar on supply and 16” duct collar
(equivalent diameter, opening is oval) on the return. The SQRPCH102 and
SQRPCH103 have 14” duct collar on supply and 18” duct collar (equivalent
diameter, opening is oval) on the return. The collars are to be slipped into
the openings, and the flanges bent around the converter. The square to round
converter is attached to the flanges of the square duct openings. The flexible
duct is then clamped on to the collars. Once the duct is affixed to the unit,
seal the collars and flanges with a proper waterproof sealant (See Figure 3).
It is strongly encouraged to use appropriately sized ducts based upon the CFM
for your application (unit’s CFM). If duct sizing through industry manuals or
air duct calculators require larger ducts than converter openings, run larger
duct size up to unit converter openings and reduce with a reducer duct fitting
or transition right at the unit.

TASLE 1 PLENUM APPLICATION
A suitable plenum or square duct must be constructed. The duct cross-sectional
area should be determined by industry duct sizing manuals or air duct
calculators.
On ductwork exposed to outside air conditions of temperature and humidity, use
an insulation with a good K factor, and a vapor barrier. Industry practices
should be followed. Balancing dampers are recommended for each branch duct in
the supply system. Ductwork should be properly supported from the unit.
NOTE: PROPER SEALING OF ALL DUCT WORK AND AIR HANDLING COMPARTMENTS IS
EXTREMELY IMPORTANT TO OVERALL UNIT EFFICIENCY.
FILTERS
Filters are not provided with unit, and must be supplied and 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. Filters must have adequate face area for the rated
quantity of the unit. See air delivery tables (Figure 4) for recommended
filter size.
PIPING
CoONDENSATE DRAIN

** 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.
HeaTt Pump START-UP PROCEDURE** -
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”.
-
Turn the thermostat system switch to “HEAT” and fan switch to “AUTO”.
-
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 de-energized (heating) position. After giving the unit time to settle out, make sure the unit is supplying heated air.
-
If the out door 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 but-DO NOT FAILTOTEST.
-
If the out door 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. 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. Make sure it operates properly.
NOTE: 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. -
For thermostats with emergency heat switch, return to step 11. 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.
-
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
-
Check to see if all supply and retum air grilles are adjusted and the air distribution system is balanced for the best compromise between heating and cooling.
-
Check for air leaks in the ductwork.
-
See Sections on Air Flow Measurement and Adjustment and Checking Charge.
-
Make sure the unit is free of “rattles”, and the tubing in the unit is free from excessive vibration. Also make sure tubes or lines are not rubbing against each other or sheet metal surfaces or edges. If so, correct the trouble.
-
Set the thermostat at the appropriate setting for cooling and heating or automatic changeover for normal use.
-
Be sure the Owner is instructed on the unit operation, filter, servicing, correct thermostat operation, etc.
-
The foregoing “Start-up Procedure and Check List” is recommended to serve as an indication 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.
-
Crankcase Heater – 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.
-
Condenser Motor – This item is activated by the contactor during heating and cooling, except during defrost and emergency heat operation.
-
Compressor – This item is activated by the contactor for heating and cooling, except during emergency heat. Itis protected by an internal overload.
-
Contactor Relay – 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 2-3 minutes unless system is low on charge or outdoor conditions are severe. (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 themostat, in the cooling mode and during defrost. It positions the reversing valve pilot valve for cooling operation.
-
Indoor Blower Motor – Units with EEM Motors The EEM model indoor blower motor is activated by the room thermostat by cooling/HEATING or fan ON position. The motor is energized by a 24 volt control signal (from thermostat Y, G or W) for EEM motors. EEM motors are constant torque motors with very low power consumption.
(See Air Flow Measurement and Adjustment for speed adjustment instructions). -
Blower Interlock Relay – This relay is used to energize the blower during the electric heat operation. Some room thermostats do not energize the motor during electric heat. This relay insures blower operation when the room thermostat energizes heat. This relay has a 240 volt coil and an 8 amp contact relay. This relay is energized by the electric heat kit sequencer.
EXPLANATION AND GUIDANCE (HEAT PUMP)
- The heat pump is a relatively simple device. It operates exactly as a Summer Air Conditioner unit when itis on the cooling cycle. Therefore, all the charts and data for service that apply to summer air conditioning apply to the heat pump when it is on the cooling cycle, and most apply on the heating cycle except that “condenser” becomes “evaporator”, “evaporator” becomes “condenser”, “cooling” becomes “heating”.
When the heat pump is on the heating cycle, it is necessary to redirect the
refrigerant flow through the refrigerant circuit external to the compressor.
This is accomplished with a reversing valve. Thus, the 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.
Figure 7 shows 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. Itis 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 liquid 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.
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 + 5°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 ITROUBLE SHOOTING
- Run unit in the heating mode (room thermostat calling for heat).
- Check unit for proper charge. NOTE: Bands of frost on the condenser coil indicate low refrigerant charge.
- Shut off power to unit.
- Disconnect outdoor fan by removing the outdoor fan motor wire from “DF2” on defrost control.
- Restart unit and allow frost to accumulate.
- After a few minutes of operation, the unit’s defrost themmostat 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.
- 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 22 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 3 seconds.
- 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.
- 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).
- Shut off power to unit.
- Replace outdoor fan motor lead to terminal “DF2” on defrost board and turn on power.
AIR FLOW MEASUREMENT AND ADJUSTMENT
After reviewing section on DUCTING, proceed with airflow measurements and
adjustments. Unit’s blower curves (in Specification Sheets) are based on
external static pressure (ESP, in. of W.C.). The duct openings on the unit are
considered internal static pressure, so 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 ducted, verify ESP with a 1” inclined manometer with
pitot tubes or a Magnahelic gauge and confirm CFM to blower curves in the
specification sheets. All units have multiple speed blower motors. If factory
selected speed is not utilized, the speed tap can be changed. Never run CFM
below 350 CFM per ton, evaporator freezing or poor unit performance is
possible.
TOTAL EXTERNAL STATIC PRESSURE
-
Using a digital manometer measure the static pressure of the retum duct at the inlet of the unit (Negative Pressure).
-
Measure the static pressure of the supply duct (Positive Pressure).
-
Add the two readings together.
NOTE: BOTH READINGS MAY BE TAKEN SIMULTANEOUSLY AND READ DIRECTLY ON THE MANOMETER IF SO DESIRED. -
Consult proper table for quantity of air.
If the external static pressure exceeds the minimum or maximum allowable
statics, check for closed dampers, dirty filter, undersized or poorly laid out
ductwork.
ADJUSTING SPEED TAP FOR INDOOR BLOWER MOTOR
EEM MOTOR
The blower motor speed for the EEM motor is controlled by three 24V low
voltage leads: green, yellow, and white. The green lead sets the speed for
fan-only mode. The yellow lead sets the speed for cooling and heat pump
heating mode (if applicable). The white lead sets the speed for electric heat
mode (emergency heat and second stage heat, if applicable).
The leads are factory connected as follows: Green to T1, Yellow to T2, and
White to T3. T1 is the low speed setting and is dedicated to fan-only mode. T2
is medium speed cooling and T3 is medium speed heating. T4 is high speed
cooling and T5 is high speed heating. To adjust the blower speed, move the
yellow and/or white wires to T4 and T5.
NOTE: IF MORE THAN ONE LEAD IS ENERGIZED AT THE SAME TIME, THE MOTOR WILL
USE THE HIGHER SPEED SETTING.
NOTE: PCH3 anD PHH3 UNITS ARE RATED FOR A maximum E.S.P. oF 0.8 EXCEPT
WHEN USING A 20Kw ELECTRIC HEATER. (THE MAXIMUM STATIC FOR 20 kKW ELECTRIC
HEAT Is 0.5 E.S.P.) WHEN THESE UNITS ARE INSTALLED IN THE 0.5 – 0.8 E.S.P.
RANGE, THE WHITE LEAD (ELECTRIC HEAT) MUST BE MOVED TO T5 FOR PROPER OPERATION
OF THE ELECTRIC HEATERS.
See CFM vs ESP tables in this manual.
Refrigerant Charge Check (Units with Fixed Orifice Devices)
After completing airflow measurements and adjustments the unit’s refrigerant
charge must be checked. All package units with fixed orifice devices are
charged using the super heat method at the compressor suction line. After
superheat is adjusted it is recommended to check unit sub-cooling at the
condenser coil liquid line out. For charge adjustments, see superheat and
subcooling charts shown for each model.
SUPERHEAT CAN BE DETERMINED AS FOLLOWS:
SUPERHEAT
CHECKING SUPERHEAT
Refrigerant gas is considered superheated whenever its temperature is higher
than the saturation temperature corresponding to its pressure. The degree of
superheat equals the degrees of temperature increase above the saturation
temperature at existing pressure. See Temperature – Pressure Chart.
- Run system at least 10 minutes to allow pressure to stabilize.
- Temporarily install thermometer on suction (large) line near compressor with adequate contact and insulate for best possible reading.
- Refer to the superheat table provided for proper system superheat. Add charge to lower superheat or recover charge to raise superheat.
Superheat Formula = Suct. Line Temp. – Sat. Suct. Temp.
Ambient Condenser Inlet Temp (°F Drybulb) | Return Air Temp. (°F Drybulb) |
---|---|
65 | 70 |
100 | – |
95 | – |
90 | – |
85 | – |
80 | – |
75 | 10 |
70 | 10 |
65 | 13 |
60 | 17 |
EXAMPLE:
a. Suction Pressure = 143
b. Corresponding Temp. °F. = 50
c. Thermometer on Suction Line = 59°F
To obtain the degrees temperature of superheat, subtract 50.0 from 59.0°F. The
difference is 9° Superheat. The 9° Superheat would fall in the * range of
allowable superheat.
SUPERHEAT = SUCTION LINE TEMP – SAT. SUCTION TEMP.
SUBCOOLING = SAT. LINE TEMP – LIQUID LINE TEMP.
CHECKING SUBCOOLING
Refrigerant liquid is considered subcooled when its temperature is lower than
the saturation temperature corresponding to its pressure. The degree of
subcooling equals the degrees of temperature decrease below the saturation
temperature at the existing pressure.
- Attach an accurate thermometer or preferably a thermocouple type temperature tester to the liquid line close to the pressure switch.
- Install a high side pressure gauge on the liquid access fitting.
- Record the gauge pressure and the temperature of the line.
- Compare the hi-pressure reading to the “Required Liquid Line Temperature” chart. Find the hi-pressure value on the left column. Follow that line right to the column under the design subcooling value. Where the two intersect is the required liquid line temperature. Alternately you can convert the liquid line pressure gauge reading to temperature by finding the gauge reading in Temperature – Pressure Chart and reading to the left, find the temperature in the °F. Column.
- The difference between the thermometer reading and pressure to temperature conversion is the amount of subcooling.
Subcooling Formula = Sat. Liquid Temp. – Liquid Line Temp.
EXAMPLE:
a. Liquid Line Pressure = 417
b. Corresponding Temp. °F. = 120°
c. Thermometer on Liquid line = 109°F.
To obtain the amount of subcooling, subtract 109°F from 120°F. The difference
is 11° subcooling. See the specification sheet or technical information manual
for the design subcooling range for your unit.

MAINTENANCE
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.
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 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 16) should help in identifying problems if the unit does not operate
properly.
SERVICE
THE FOLLOWING INFORMATION IS FOR USE BY QUALIFIED SERVICE AGENCY ONLY: OTHERS
SHOULD NOT ATTEMPT 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:
- 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.
- No voltage at unit’s solenoid – Check unit voltage. If no voltage, check wiring circuit.
- Valve will not shift:
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 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.

the heating and cooling seasons begin.
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. REPLACE OR CLEAN FILTER
IMPORTANT NOTE: NEVER OPERATE UNIT WITHOUT A FILTER INSTALLED AS DUST AND
LINT WILL BUILD UP ON INTERNAL PARTS RESULTING IN LOSS OF EFFICIENCY,
EQUIPMENT DAMAGE AND POSSIBLE FIRE.
A RETURN AIR FILTER IS NOT SUPPLIED WITH THIS UNIT; HOWEVER, THERE MUST BE A
MEANS OF FILTERING THE RETURN AIR. AN INDOOR AIR FILTER MUST BE USED WITH YOUR
COMFORT SYSTEM. A PROPERLY MAINTAINED FILTER WILL KEEP THE INDOOR COIL OF YOUR
COMFORT SYSTEM CLEAN. A DIRTY COIL COULD CAUSE POOR OPERATION AND/OR SEVERE
EQUIPMENT DAMAGE.
The installer of your unit can tell you where your filter(s) are and how to
clean or replace them.
Check your return filter(s) at least once every two months.
When they are dirty, replace or clean as required. Disposable type filters
should be replaced. Reusable type filters may be cleaned.
NOTE: REUSABLE TYPE FILTERS SHOULD BE WASHED WITH WARM WATER, DRIED
COMPLETELY AND SPRAYED WITH AN ADHESIVE ACCORDING TO THE MANUFACTURERS
RECOMMENDATIONS.
You may want to ask your dealer about high efficiency filters. High efficiency
filters are available in both electronic and non-electronic types. These
filters can do a better job of catching small airborne particles.
Improper filter maintenance is the most common cause of inadequate heating or
cooling performance. Filters should be cleaned (permanent) or replaced
(disposable) every two months or as required. When replacing a filter, it must
be
replaced with a filter of the same type and size and always make certain the
air flow arrows on the filter point in the proper direction.
CONDENSER AND EVAPORATOR MoOTORS
The bearings on the air circulating blower motor and condenser motor are
permanently lubricated and require no further lubrication.
COMPRESSOR
The compressor motor is hermetically sealed and does not require additional
oiling.
ALumiNum INDOOR CoiL CLEANING (QUALIFIED SERVICER ONLY)
This unit is equipped with an aluminum tube evaporator coil. The safest way to
clean the evaporator coil is to simply flush the coil with water. This
cleaning practice remains as the recommended cleaning method for both copper
tube and aluminum tube residential cooling coils.
An alternate cleaning method is to use one of the products listed in the
technical publication TP-109 (shipped in the literature bag with the unit) to
clean the coils. The cleaners listed are the only agents deemed safe and
approved for use to clean round tube aluminum coils. TP-109 is available on
the web site in Partner Link > Service Toolkit.
NOTE: ENSURE COILS ARE RINSED WELL AFTER USE OF ANY CHEMICAL CLEANERS.
ANNUAL INSPECTION (QUALIFIED SERVICER ONLY)
Your package unit should be inspected by a qualified installer, or service
agency at least twice every year. This check should be performed before the
heating and cooling seasons begin. This will ensure that the system is
performing properly and safely. Repair as necessary.
- Check physical support of the unit. Ensure it is sound without any sagging, cracks, or gaps, around the base.
- Check for obvious signs of deterioration of the unit.
- Check both condenser and evaporator coil to make sure each are clean.
- Return Air Connection. Check for physical soundness and ensure that the connection is firmly sealed to the package unit casing.
- Wiring. Check wires for damage. Check electrical connections for tightness and/or corrosion.
- Filters. Check that filters are clean and in the proper placement in the unit or duct system.
- Louvers. Inspect air inlet louvers inside the heat exchanger compartments. Ensure the area is clean and free of dirt and debris.
