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
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 12” from the 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. See FIGURE 1: GROUND LEVEL INSTALLATION below.

Unit Location
Consider the effect 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 of 2” clearance under the outdoor coil is required in milder climates.

Roof Top Installation (Figure 2)

1. 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.
2. Make a proper consideration for weather-tight integrity of the roof and proper drainage of condensate.
3. To ensure proper condensate drainage, unit must be installed in a level position.
4. Consideration should also be given to shade, appearance, and noise.

Roof Curb Installations
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. See FIGURE 3: ROOFCURB INSTALLATION.

Rigging Details

• WARNING To prevent property damage, the unit should remain in an upright position during all rigging and moving operations. To facilitate lifting and moving when crane is used, place the unit in an adequate cable sling.
• CAUTION If units are lifted two at a time, the fork holes on the condenser end of the unit must not be used. Minimum for length is 42” to prevent damage to the unit; however, 48” is recommended.
• NOTE : Provisions for forks have been included in the unit base frame. No other fork locations are approved.
• WARNING To avoid possible property damage, personal injury or death, ensure the roof has sufficient structural strength to carry the weight of the unit(s), roofcurb, snow loads, and water loads as required by local codes. Consult a structural engineer to determine the weight capabilities of the roof.
• CAUTION To avoid possible personal injury, a safe, flat surface for service personnel should be provided.
• WARNING To prevent possible equipment damage, property damage, personal injury or death, the following bullet points must be observed when installing the unit.

Unit must be lifted by the four lifting holes located at the base frame corners. See Figure 4: Rigging

• Lifting cables should be attached to the unit with shackles
• The distance between the crane hook and the top of the unit must not be less than 60”.
• Two spreader bars must span over the unit to prevent damage to the cabinet by the lift cables. Spreader bars must be of sufficient length so that cables do not come into contact with the unit during transport.
• Remove wood struts mounted beneath unit base frame before setting unit on roof curb. These struts are intended to protect unit base frame from forklift damage. Removal is accomplished by extracting the sheet metal retainers and pulling the struts through the base of the unit. Refer to rigging label on the unit.

Refer to the Roof Curb Installation Instructions for proper curb installation. Curbing must be installed in compliance with the National Roofing Contractors Association Manual.

CIRCULATING AIR AND FILTERS

Airflow Conversion
Units can easily be converted from horizontal to down discharge air flow delivery. See FIGURE 5A: HORIZONTAL FLOW DUCT COVER INSTALLATION and FIGURE 5B: DOWNFLOW DUCT COVER INSTALLATION. 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.

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.

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., 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 return outlets. Use of non-flammable weatherproof flexible connectors on both supply and return connections at the unit to reduce noise transmission is recommended.

It is preferable to install the unit on the roof of the structure if the registers or diffusers are 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 in the table below. (See Specification Sheets for Dimension details).

The SQRPG101, SQRPG102, and SQRPG103 fit up to the Return and Supply Downflow vents having dimensions: Return (22 ¾” x 12 ¼”) and Supply (22 ¼” x 14 ¾”). The SQRPGH101, SQRPGH102, and SQRPGH103 fit up to the Horizontal Return and Supply downflow vents having dimensions: Medium Chassis (16 ½” x 16 ½”) and Large Chassis (18 ½” x 18 ½”). The Medium Chassis kits transition to a 16” Diameter and the Large Chassis kits transition to an 18” Diameter (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 6: MANUFACTURED HOME MODIFICATION KIT.

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 requires 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.

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 ductwork and air handling compartments is extremely important to overall unit efficiency.

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. For unit filter size information, see table below for recommended filter size.

UNIT| 2 TON| 2 1/2 TON| 3 TON| 3 1/2 TON| 4 TON| 5 TON
---|---|---|---|---|---|---
Min. Filter Size| (1)25X25X1| (1)25X25X1| (1)25X25X1| (1)25X25X1| (2)20X20X1| (2)20X20X1

CONDENSATE DRAIN PIPING
The condensate drain connection of the evaporator is a ¾” NPT half coupling. A trap must be provided to have proper condensate draining. Install condensate drain trap as shown in FIGURE 7: CONDENSATE DRAIN TRAP PLUMBING. Ensure drain connection is 3/4” or larger. Do not operate unit without trap and ensure unit is level or slightly inclined toward drain.

ELECTRICAL WIRING

CAUTION To avoid property damage or personal injury due to fire, use only copper conductors.

All wiring should be made in accordance with the National Electrical Code. The local power company should be consulted to determine the availability of sufficient power to operate the unit. The voltage, frequency, and phase at the power supply should be checked to make sure it corresponds to the unit’s RATED VOLTAGE REQUIREMENT.

Install a branch circuit fused disconnect near the unit, in accordance with the N.E.C. or local codes. Wire sizes and overcurrent protection should be determined from the unit nameplate ampacity and in accordance with N.E.C. and local building codes. Under no circumstances should wiring be sized smaller than is recommended by either of these two sources.

Fuses smaller than that recommended on the unit nameplate could result in unnecessary fuse failure or service calls. The use of protective devices of larger size than indicated could result in extensive damage to the equipment. The manufacturer bears no responsibility for damage caused to equipment as result of the use of larger than is recommended size protective devices.
All units have undergone a run test prior to packaging for shipment. This equipment has been started at minimum rated voltage and check for satisfactory operation. Do not attempt to operate this unit if the voltage is not within the minimum and maximum voltages shown on the nameplate.

The units are designed for operation at the voltage, frequency, and phase as shown on the rating plate. All internal wiring in the unit is complete. It is necessary to bring in the power supply to the contactor as shown on the unit wiring diagram which is supplied with each unit. The low voltage wiring must be connected between the unit control panel and the room thermostat.
All exterior wiring must be within approved weatherproof conduit. The unit must be permanently grounded in accordance with local codes, or in absence of local codes with N.E.C. ANSI/NFPA NO. 70-1984 or latest edition by using ground lug in the control box.

DO NOT EXCEED THE MAXIMUM OVERCURRENT DEVICE SIZE SHOWN ON UNIT DATA PLATE.
Fuses or HACR type circuit breakers may be used where codes permit.

IMPORTANT NOTE: Units may be equipped with a single pole contactor. Caution must be exercised when servicing as only one leg of the power supply is broken with the contactor.

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.

CAUTION To avoid the risk of electrical shock, wiring to the unit must be polarized and grounded.

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.

Air Conditioner Start-Up Procedure

1. Turn thermostat system switch to “Cool,” and fan switch to “Auto” and turn 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 operate after a 10 second delay.
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.

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.

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 contactor is energized. The compressor, blower and fan should then be running. After the colling mode is checked out, turn the thermostat system switch to “OFF”.

2. Turn the thermostat system switch to “HEAT” 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 de-energized (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 cutout when in heating mode. 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 FAIL TO TEST.

5. 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: 5-Ton 13.4 SEER2 models have two stages of compressor heat. During resistance heat test, increase temperature setting until third stage heat is energized.
   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.

6. THERMOSTATS WITH EMERGENCY HEAT. 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.

7. 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 Check

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.
2. Check for air leaks in the ductwork.
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. Also make sure tubes or lines are not rubbing against each other or sheet metal surfaces or edges. If discovered, ensure issue is corrected.
5. Set the thermostat at the appropriate setting for cooling and heating or automatic changeover for normal use.
6. Ensure the Owner is instructed on the unit operation, filter, servicing, correct thermostat operation, etc.

NOTE: The “Air Conditioner Start-up Procedure” is a recommended step as it serves as a 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.

• Crankcase Heater – This item is “ON” whenever power is supplied to the unit and 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 & L2 terminals. Condenser Motor – This item is activated by the contactor during heating and cooling, except during defrost and emergency heat operation. On 460V heat pumps, the condenser motor is activated by the CMR.

• Compressor – This item is activated by the contactor for heating and cooling, except during emergency heat. It is 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°F) 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 colling mode and during defrost.
  It positions the reversing valve pilot valve for cooling operation.

• Indoor Blower Motor – Units with EEM Motors Only. The EEM model indoor blower motor is activated by the room thermostat by cooling/HEATING or fan ON position. EEM motors are constant torque motors with 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 ensures blower operation when the room thermostat energizes heat. This relay is energized by the electric heat kit sequencer.

HEAT PUMP OPERATION

Cooling Cycle
When the heat pump is in the cooling cycle, it operates exactly as an Air Conditioner Unit. See Figure 9: HEAT PUMP COOLING SCHEMATIC

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 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 figure, FIGURE 10: HEAT PUMP HEATING SCHEMATIC, shows a schematic of the heat pump in the heating cycle.

For 5-Ton Heat Pump unit, the expansion devices are Thermal Expansion Devices (TXV) and perform the same function on the heating cycle as on the cooling cycle. The TXVs 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 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 30 ± 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°± 5°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/Troubleshooting TESTING DEFROST CONTROL

NOTE: PCBDM133 Defrost controls have a three (3) minute compressor off cycle delay.
NOTE: The PCBDM133 defrost controls are 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.

To check the defrost control for proper sequencing, proceed as follows: With power ON;
unit not running.

1. Jumper defrost thermostat by placing a jumper wire across the terminals “DFT” and “R”/” R-DFT” at defrost control board.

2. Remove jumper from timer pins and jump across test pins on defrost control board.
   NOTE: Do not use screwdriver or field supplied jumper to test the control.

3. Set thermostat to call for heating. System should go into defrost within 21 seconds.

4. Immediately remove jumper from test pins.

5. Using VOM check for voltage across terminals “C & O”. Meter should read 24 volts.

6. Using VOM check for voltage across fan terminals DF1 and DF2 on the board. Should read line voltage (208-230 VAC) indicating the relay is open in the defrost mode.

7. Using VOM check for voltage across “W”/”W2” & “C” terminals on the board. Should read 24 volts.

8. If not as above, replace control board.

9. Set thermostat to off position and disconnect power. Remove jumper from defrost thermostat and replace timer jumper to the desired defrost time.

NOTE: Remove jumper across defrost thermostat before returning system to service. See Figure 12: Defrost control Wiring Diagram.

Testing Defrost Thermostat

1. Install a thermocouple type temperature test lead on the tube adjacent to the defrost control. Insulate the lead point of contact.
2. Check the temperature at which the control closes its contacts by lowering the temperature of the control. It should close at approximately 30°F.
3. Check the temperature at which the control opens its contacts by raising the temperature of the control. It should open at approximately 60°F. If not as above, replace control.

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 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.

NOTE: Never run CFM below 300 CFM per ton, evaporator freezing, or poor unit performance is possible.

TOTAL EXTERNAL STATIC PRESSURE

1. Using a digital manometer measure the static pressure of the return duct at the inlet of the unit (Negative Pressure). SEE FIGURE 13: TOTAL EXTERNAL STATIC.

2. Measure the static pressure of the supply duct (Positive Pressure).

3. Add the two readings together
   NOTE: Both readings may be taken simultaneously and read directly on the manometer if so desired.

4. 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).

EEM Motor Speed Adjustment
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.
See appendix for Blower Performance Data tables.

*[GPC/PH]M3 CFM Delivery and Adjustments**
See Appendix for CFM Output, Adjustments, and DIP switch settings.

*[GPC/PH]M3 Thermostat “Fan Only” Mode**
During Fan Only Operations, the CFM output is 50% of the high stage cooling setting.

SUPERHEAT AND SUBCOOLING

Checking Subcooling
NOTE: Units with a TXV should be charged to Subcooling only.
EXAMPLE:

a. Liquid Line Pressure = 417 PSI
b. Corresponding Temp. = 120°F
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.

SUBCOOLING FORMULA = SATURATED LIQUID LINE TEMPERATURE – LIQUID LINE TEMPERATURE
Checking Superheat
EXAMPLE:

a. Suction Pressure = 143 PSI
b. Corresponding Temp. = 50°F
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.

Superheat Adjustment
NOTE: Superheat adjustments should not be made until indoor ambient conditions have stabilized. This could take up to 24 hours depending on indoor temperature and humidity. Before checking superheat, run the unit in cooling for 10-15 minutes or until refrigerant pressures stabilize. Use the following guidelines and methods
to check unit operation and ensure that the refrigerant charge is within limits.

For TXV systems, to adjust superheat, unscrew the cover from the expansion valve, locate the adjustment screw, and turn it clockwise (in) to increase superheat or counter-clockwise (out) to decrease superheat. It is recommended to make small adjustments at a time, 1/8-1/4 turn increments. Replace adjustment cap. Wait a minimum of 10 minutes between adjustments to allow time for the TXV and pres-sures to stabilize.

Refrigerant Charge Check
NOTE: For optimal performance, follow charging instructions below.

Figure 14: Design Superheat and Subcooling Units with Fixed Orifice Devices

All package units with fixed orifice devices are charged using the superheat method at the compressor suction line. To increase super heat, remove charge and to decrease super heat, add charge. After superheat is adjusted, it is recommended to check unit subcooling at the condenser coil liquid line. See Figure 14: DESIGN SUPERHEAT AND SUBCOOLING table for targets on each model.

Units with Expansion valve (TXV)
Single Stage Cooling Application: Refer to the Design Superheat & Subcooling table.
Two-Stage Cooling Application: Run unit on Low Stage cooling and refer to Design Superheat & Subcooling table.

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. System should have a subcooling and superheat within the range listed on the Design Superheat and Subcooling table.

   • If subcooling and superheat are low, adjust TXV superheat, then check subcooling.
     NOTE: To adjust superheat, turn the valve stem clockwise to increase and counterclockwise to decrease.

   • If subcooling is low and superheat is high, add charge to raise subcooling then check superheat.

   • If subcooling and superheat are high, adjust TXV valve superheat, then check subcooling.

   • If subcooling is high and superheat is low, adjust TXV valve superheat and remove charge to lower the subcooling.
     NOTE: Do NOT adjust the charge based on suction pressure unless there is a gross undercharge.

4. Disconnect manifold set, installation is complete.

ELECTRICAL HEAT INSTALLATION & ADJUSTMENT

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 (see Appendix) 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.

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 shift:
   • Undercharged – Check for leaks.
   • Valve Body Damaged – Replace valve.
   • 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.

REVERSING VALVE TROUBLESHOOTING

Checking Reversing Valve and Solenoid
Reversing valve used in heat pumps could potentially leak internally. Discharge gases can leak into the suction inside the valve. Compound gages will give the same symptoms as bad compressor valves or broken scroll flanks. The temperature between true suction and the suction line after the valve should not be greater than 4 degrees. Note: The center tube is always the suction line and should be cold.

Troubleshooting the Reversing Valve for Electrical Failure

1. Place unit into the cooling mode. Test for 24 volts at the solenoid. If there is no voltage present at coil, check the control voltage.
2. If voltage is present, loosen the nut on the top of the coil. Remove the coil, there should be slight resistance.
3. If the slight resistance is felt, remove the coil. As you remove the coil listen carefully, an audible click should be detected. The clicking is due to the movement of the pilot valve plunger. The absence of a clicking sound indicates the plunger is stuck.

Troubleshooting Mechanical Failures on a Reversing Valve by Pressure

1. Troubleshooting the reversing valve can be done by pressure and touch.
2. Raise the head pressure. In the cooling mode block the fan exhaust. Once head pressure has been raised, cycle between cooling and heating and see if the piston can be freed.

Troubleshooting Mechanical Failures on a Reversing Valve by Temperature

1. When operating properly the valve contains refrigerant gases at certain temperatures.
2. The discharge line should be the same temperature after the valves discharge line.
3. The true suction should be the same as the suction line after the valve. If there is a 4-degree difference, valve is leaking

When stuck in the mid-position, part of the discharge gas from the compressor is directed back to the suction side, resulting in excessively high suction pressure. An increase in the suction line temperature through the reversing valve can also be measured. Check operation of the valve by starting the system and switching the operation from COOLING to HEATING cycle.

If the valve fails to change its position, test the voltage (24V) at the valve coil terminals, while the system is on the COOLING cycle.

If voltage is registered at the coil, tap the valve body lightly while switching the system from HEATING to COOLING, etc. If this fails to cause the valve to switch positions, remove the coil connector cap and test the continuity of the reversing valve solenoid coil. If the coil does not test continuous – replace it. If the coil test continuous and 24 volts is present at the coil terminals, the valve is inoperative – replace it.

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.

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.

HOMEOWNER’S ROUTINE MAINTENANCE RECOMMENDATIONS
WE STRONGLY RECOMMEND A BI-ANNUAL MAINTENANCE CHECKUP BE PERFORMED BY A QUALIFIED SERVICE AGENCY BEFORE 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 re-quired. 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 MOTORS
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 re-quire 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.

Before Calling Your Servicer

• Check the thermostat to confirm that it is properly set.
• Check the disconnect switch near the unit to confirm that it is closed.
• Check the electrical panel for tripped circuit breakers or failed fuses . Reset the circuit breakers or replace fuses as necessary.
• Check for blockage of the indoor air inlets and outlets. Confirm that they are open and have not been blocked by objects (rugs, curtains or furniture).
• Check for obstructions on the unit . Confirm that it has not been covered on the sides or the top. Remove any obstruction that can be safely removed. If the unit is covered with dirt or debris, call a qualified servicer to clean it.
• Check the filter. If it is dirty, clean or replace it.
