CONTROL PANEL-Contains a five position mode selector switch and a temperature control
thermostat.
NOTE
The control panel is shown in its location when the air conditioner is installed as a self-contained unit.
The control panel is designed so that it may be removed from the cabinet and installed in a remote
JUNCTION BOXContains 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 FILTER AND DAMPER--Provides filtered outside air.
REFRIGERANT SIGHT GLASS (liquid sight indicator)--Allows visual inspection and indicates
condition
of liquid refrigerant when the unit is operating in the cool mode.
INPUT POWER RECEPTACLE--For connection of external power source cable.
NOTE
The air conditioner is designed so that the input power receptacle maybe used in the rear panel
location
shown, or it may be moved to one of four other alternative locations. See installation instructions
HIGH AND LOW REFRIGERANT PRESSURE CUTOUT SWITCHES (S6 and S7)--Protects
commessor
from possible damage due to excessively high or low refrigerant pressures.
COMPRESSOR CIRCUIT BREAKER (CB1) RESET KNOB--Actuates a push-pull type control cable
resetting compressor circuit breaker.
CONDENSER AIR OUTLET GRILLE--Protects personnel from injury and fan from damage.
COMPRESSOR (61)--Pumps refrigerant through the system during cooling operations.
CONDENSER COIL--Serves as a heat exchanger by transferring heat from the refrigerant passing
through the tubing to the air passing over the tubing and fins.
CONDENSER COIL GUARD-Protects coil from damage.
CONDENSATE WATER DRIP PAN AND DRAIN TRAP--The drip pan is located directly below the
evaporator coil and mist eliminator and is built into the casing. Its purpose is to collect condensate that
drips off the evaporator coil and mist eliminator during cooling operations. Condensate water then flows
through tubing to the drain traps located inside the lower right and left hand front corners of the
cabiniet.
