PRINCIPLES OF OPERATION.
a. General. The air conditioner is a fully self-contained unit capable of providing cooling, heating or ventilation to
the conditioned area.
(1) The cooling section consists primarily of a compressor, high and low pressure cut-out switches,
condenser coil, evaporator coil, and a fan motor which operates both a condenser fan and an evaporator fan on a
common shaft. When the selector switch is placed in the "COOL" position, the fan motor and the compressor start. The
cooling section is under control of the thermostat, which serves to maintain the temperature of the conditioned area at the
