1-7. LOCATION AND DESCRIPTION OF MAJOR COMPONENTS - Continued.
12.
REFRIGERANT SIGHT GLASS (Iiquid 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.
13.
NOTE
The air conditioner is designed so that the input power receptacle may be used in the
front panel location shown, or it may be moved to one of three other alternative locations.
See installation instructions (para 4-9).
HIGH AND LOW REFRIGERANT PRESSURE CUTOUT SWITCHES (S6 and S7) - Protects compressor from pos-
14.
sible damage due to excessively high or low refrigerant pressures.
15.
COMPRESSOR CIRCUIT BREAKER (CB1) RESET KNOB- Actuates a push-pull type control cable for resetting
compressor circuit breaker.
16.
CONDENSER AIR OUTLET GRILLE - Protects personnel from injury and fan from damage.
COMPRESSOR (B1) - Pumps refrigerant through the system during cooling operations.
17.
CONDENSER COIL - Serves as a heat exchanger by transferring heat from the refrigerant passing through the
18.
tubing to the air passing over the tubing and fins.
19.
CONDENSER COIL GUARD - Protects coil from damage.
CONDENSATE WATER DRIP PAN AND DRAIN TRAP - The drip pan is located directly below the evaporator coil
20.
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 comers of the cabinet. The drain traps contain check valves that prevent
air flow between the condenser and evaporator sections through the drain tubing.
FAN MOTOR (B2) - Drives the conditioned air (evaporator) fan and the condenser fan.
21.
CONDENSER FAN - Draws air through the condenser coil and discharges the heated air back to the outside during
22.
cooling operations.
