Receiver. The receiver acts as a storage tank for the liquid refrigerant.
Solenoid Valve, Liquid Line. This valve is normally open when the compressor is NOT running and
is thermostatically controlled during cooling cycles when operating in the COOL mode.
Pressure Regulating Valve. This valve regulates the suction pressure by recirculating a part of the
compressor discharge hot gas to the suction line when the suction pressure drops below a preset value. This
action prevents frosting of the evaporator coil.
Expansion Valve. Meters refrigerant flow to the evaporator during cooling cycles when operating in
the COOL mode.
Evaporator Coil. Similar in construction to the multiple-tube, finned condenser coil. This coil serves
as a eat exchanger for the refrigerant to absorb heat from the room or enclosure air circulated through the
Heating Elements. Consists of two banks of heating elements. Only one bank operates in the "LOW
HEAT" mode. Both banks operate in the "HIGH HEAT" mode. One bank shuts off when the thermostat is
satisfied in both HIGH and LOW HEAT modes.
Mist Eliminator. The purpose of the mist eliminator is to trap droplets of condensed water from the
evaporator, so that they will not be blown into the air conditioned space.
Input Power Receptacle (Alternate Location). The main power cable may be connected here. See
item 10 for primary location. See installation instructions for switch over instructions if this power receptacle is
Refrigerant Sight Glass. Visually indicates the condition of the refrigerant flowing in the refrigerant
lines during cooling cycles when operating in the COOL mode.
Condenser Fan Switch. Controls fan speed. At temperatures above 100°F (38°C) closes to allow
high speed; below 100°F (38°C) opens to allow only low speed operation.
Actuating Cylinder. This hydraulic cylinder operates discharge louver assembly. It will start to open
the louver assembly at 150 to 180 psig (10.55 to 12.66 kg/cm2) and fully open louver assembly at 220 to 260 psig
(15.74 to 18.28 kg/cm2) compressor discharge pressure to allow unit operation when outside temperature is
