when required, from the outside of the unit, through the fresh air filter and ventilation duct; air

is then forced over the heater elements through evaporator coil, mist eliminator and outlet louver.

The outlet louver has adjustable blades for directing the air flow into a desirable pattern within

the space being conditioned. The evaporator fan speed is controlled by a toggle switch on the

control module.

Condenser Section. The condenser section (figure 1-2 ) located in the rear part of the

air conditioner contains the condenser coil, condenser coil guard, two condenser motors and fans,

motor compressor, condensor, condensor fan housings and louvers, louver actuator, ventilation

air duct, fresh air filter and vent screen, thermal switch, refrigerant liquid sight indicator,

solenoid valves, expansion valve, pressure relief valve, system access service valves, filter drier,

refrigerant liquid receiver, accumulator, associated electrical wiring and refrigerant tubing and

an alternate power input connector. The condenser fan speed controlled by a thermal switch

located on the rear of unit. At ambient temperatures of 100F 5F (38C 3C) or higher, the

condenser fan motors will operate at high speed (3750 RPM); and at ambient temperatures below

100F (38C) , the motor will operate at low speed (1800 RPM). Due to possible thermal lag, the

change over may be slow to react when the ambient temperature drops below the 100F (38C)

changeover point.
