Functional Component Definitions

MECHANICAL COMPONENTS

Vent door Allows introduction of fresh air into the room and/or exhausts stale room air outside (on select models.)

Plenum assembly Diffuser with directional louvers used to direct the conditioned airflow.

Blower wheel 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.

ELECTRICAL COMPONENTS

Thermostat Used to maintain the specified room side comfort level

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 sup- ply to the fan motor through the thermostat, which allows for a cycle-fan operation.

Fan Motor Dual-shafted fan motor operates the indoor blower wheel and the condenser fan blade simultaneously.

Heat anticipator Used to provide better thermostat and room air temperature control.

HERMETIC COMPONENTS

Compressor Motorized device used to compress refrigerant through the sealed system.

Check valve A pressure-operated device 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.)
