Read, understand and follow the above warning.

 

 

 

 

 

Wire Size

Use ONLY wiring size recommended for single outlet branch circuit.

Fuse/Circuit Breaker

Use ONLY the correct HACR type and size fuse/circuit breaker. Read electrical ratings on unit’s

 

rating plate. Proper circuit protection is the responsibiity of the homeowner.

Grounding

Unit MUST be grounded from branch circuit through service cord to unit, or through separate

 

ground wire provided on permanently connected units. Be sure that branch circuit or general

 

purpose outlet is grounded.

Receptacle

The field supplied outlet must match plug on service cord and be within reach of service cord.

 

Do NOT alter the service cord or plug. Do NOT use an extension cord. Refer to the table above

 

for proper receptacle and fuse type.

FUNCTIONAL COMPONENTS

A. Mechanical components

Drain pan valve

Temperature-sensitivevalve that opens up to drain off condensate water when the outside temperature falls below 40°F and closes when the outside temperature reaches 60°F

Plenum assembly

Diffuser with directional louvers used to direct the conditioned airflow

Blower whee

Attaches to the indoor side of the fan motor shaft and is used for distributing unconditioned, room side air though the heat exchanger and delivering conditioned air into the room

Slinger fan blade

Attaches to the outdoor side of the fan motor shaft and is used to move outside air through the condenser coil, while slinging condensate water out of the base pan and onto the condenser coil, thus lowering the temperature and pressures within the coil

B. Electrical components

Thermostat

Used to maintain the specified room side comfort leve

System switch

Used to regulate the operation of the fan motor, the compressor or to turn the unit off. For troubleshooting, refer to the wiring diagrams and schematics in the back of this service manual

Capacitor

Reduces line current and steadies the voltage supply, while greatly improving the torque characteristics of the fan motor and compressor motor.

MoneySaver® switch

When engaged, it sends the power supply to the fan motor through the thermostat, which allows for a cycle-fanoperation

Fan Motor

Dual-shaftedfan motor operates the indoor blower wheel and the condenser fan blade simultaneously.

Solenoid

Used to energize the reversing valve on all heat pump units.

Heating element

Electric resistance heater

Heat anticipator

Used to provide better thermostat and room air temperature control.

C. Hermetic components

Compressor

Motorized device used to compress refrigerant through the sealed system.

Reversing valve

A four-wayswitching device used on all heat pump models to change the flow of refrigerant to permit heating or cooling.

Check valve

A pressure-operateddevice used to direct the flow of refrigerant to the proper capillary tube, during either the heating or cooling cycle

Capillary tube

A cylindrical meter device used to evenly distribute the flow of refrigerant to the heat exchangers (coils.)
