CONTROL PANEL - Contains a five position mode selector switch, a temperature
control thermostat and two position fan toggle switch.
JUNCTION BOX - Contains and protects electrical system control devices.
EVAPORATOR COIL - Serves as a heat exchanger by transferring heat from the
air passing over the tubing and fins to the refrigerant passing through the
tubing.
FABRIC COVER - Shown on rear view in stowed (operational) position. When
rolled down and snapped it protects the rear (exposed) surface of the unit.
FRESH AIR DAMPER - Provides outside air.
