OMPONENTS ontactor This control is activated (closed) by the room thermostat for both heating and cooling. The contactor has a V coil and supplies power to the compressor and outdoor fan motor. rankcase Heater This item is ON whenever power is supplied to the unit and the crankcase heater thermostat is closed. The crankcase heater thermostat closes at 7º (9º) and opens at 85º (9º). 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 L and L terminals. ondenser Motor This item is activated by the contactor during heating and cooling, except during defrost and emergency heat operation. ompressor This item is activated by the contactor for heating and cooling, except during emergency heat. It is protected by an internal overload. ontactor elay This control is activated by the thermostat (V coil) and supplies power to the contactor. Defrost ontrol The Defrost control provides time/temperature initiation and termination of the defrost cycle. hen a defrost cycle is initiated, the defrost control shifts the reversing valve to ooling mode, stops the outdoor fan and brings on supplemental heat. Normally, a defrost cycle will take only to minutes unless the system is low on refrigerant charge or outdoor conditions are severe (windy and cold). The defrost control also provides for a -minute off-cycle compressor delay. Outdoor Thermostat These optional controls are used to prevent full electric heater operation at varying outdoor ambient ( to 5 [-8º to 7º]). They are normally open above their set points and closed below to permit staging of the indoor supplement heater operation. If the outdoor ambient temperature is below (-8 ) with 5% or higher relative humidity (H), an outdoor thermostat (OT) must be installed and set at ( ) on the dial. ailure to comply with this requirement may result in damage to the product which may not be covered by the manufacturer s warranty. eversing Valve oil 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 lower Motor This is activated by setting the room thermostat to OOLIN or AN ON position. The motor is energized through the ETD for PS motors and directly by the room thermostat for X- motors ( or 5 Ton units). X- motors are constant torque motors with very low power consumption. This motor is energized by a V signal from the thermostat. See Airflow Measurement and Adjustment for speed adjustment instructions. lower Interlock elay Single-Phase PS Models Only 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 has a -volt coil and an 8-amp contact relay. This relay is energized by the electric heat kit sequencer. HEAT PUMP OPEATION ooling ycle hen the heat pump is in the cooling cycle, it operates exactly as a summer air conditioner unit. In this mode, all the charts and data for service that apply to summer air conditioning apply to the heat pump. Most apply on the heating cycle except that the condenser becomes the evaporator, the evaporator becomes the condenser and cooling becomes heating. Heating ycle The heat pump operates in the heating cycle by redirecting refrigerant flow through the refrigerant circuit external to the compressor. This is accomplished 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. hen 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 illustrations 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. 9

Defrost ontrol 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, and 9 minutes may be selected by setting the circuit board jumper to, and 9 respectively. Accumulation of time for the timing period selected starts when the sensor closes (approximately [5º]), 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. hen the sensor opens (approximately [º]), the defrost cycle is terminated and the timing period is reset. If the defrost cycle is not terminated due to the sensor temperature, a -minute override interrupts the unit s defrost period. ircuit oard D H H A I I E A. Indoor coil. Service valves.

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. hen 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 5 (7º). 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 the freezing point, frost forms on the surfaces of the outdoor coil under certain weather conditions related to 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.

11 . After a few minutes of operation, the defrost thermostat should close. To verify this, check for volts between DT and on the control board. If the temperature at the thermostat is less than 8 (-º) and the thermostat is open, replace the defrost thermostat, since it is defective. 7. hen the unit s defrost thermostat has closed, short the test pins on the circuit board until the reversing valve shifts, indicating defrost. This should take up to seconds depending on what timing period the control is set. NOTE: After defrost initiation, the short must instantly be removed, or the unit s defrost period will last only. seconds. 8. After the unit s defrost thermostat has terminated, check the defrost thermostat for volts between DT and. The reading should indicate volts (open sensor). 9. Turn off power to the unit.. eplace the outdoor fan motor lead to terminal D on the circuit board and turn on power. AILO MEASUEMENT AND ADJUSTMENT After reviewing the Ductwork section in irculating Air and ilters, proceed with the airflow measurements and adjustments. The unit blower curves (see Specification Sheets) are based on the external static pressure (ESP per in./..). 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 M required by the application (for example, home, building, etc.). In general, M per ton of cooling capacity is a rule of thumb. Some applications depending on the sensible and latent capacity requirements may need only 5 M or up to 5 M per ton. heck condition space load requirements (from load calculations) and equipment expanded ratings data to match M and capacity. After the unit is set and the ductwork completed, verify the ESP with a " (.5 cm) inclined manometer with pitot tubes or a Magnahelic gauge and confirm M to blower curves in the Specification Sheets. All units have -speed blower motors. If the low speed is not utilized, the speed tap can be changed to medium or high speed. NOTE: Never run M below 5 M per ton. Evaporator freezing or poor unit performance is possible.

13 efrigerant harge hecks After completing airflow measurements and adjustments, the unit s refrigerant charge must be checked. The unit is factory charged based on M per ton at minimum ESP per AHI test conditions (generally between.5 and.5 ESP). hen air quantity or ESP differs from this, charge must be readjusted to the proper amount. All package units are charged to the superheat method at the compressor suction line (these are fixed orifice devices). or charging in the warmer months, 8º +/-º superheat at the compressor is required at conditions: 95º (5º) outdoor ambient (dry bulb temperature), 8º (7º) dry bulb / 7º (9º) wet bulb indoor ambient, approximately 5% humidity. This superheat varies when conditions vary from the conditions described. A superheat charge chart is available for other operating conditions. Use it to provide the correct superheat at the conditions the unit is being charged at. After superheat is adjusted it is recommended to check unit subcooling at the condenser coil liquid line out. In most operating conditions º to 5º of subcooling is adequate. Determine Superheat. ead suction pressure..

Service NOTE: The following information is for use by qualified service agency only. Others should not attempt to service this equipment. ommon auses of Unsatisfactory Operation of Heat Pump on the Heating ycle. Inadequate Air Volume Through Indoor oil hen 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 cutout. Outside Air Into eturn 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 5 (8º). 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 ontact The defrost terminating sensor must make good thermal contact with the outdoor coil tubing. Poor contact may not terminate the defrost cycle quickly enough to prevent the unit from cutting out on high discharge pressure. Malfunctioning eversing 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 the solenoid heck unit voltage. If no voltage, check wiring circuit.. Valve will not shift If the unit is undercharged, check for leaks. If valve body damaged, replace valve. If unit is properly charged, and 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. NOTE: 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, turn off the unit and wait until the discharge and suction pressure equalize, and repeat above steps. If the valve does not shift, replace it. The self-contained package air conditioner or 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.
