DESCRIPTION
The air conditioning system is a cycling clutch type.
Compressor is cycled on and off by a thermostatic switch to maintain
constant cooling rate. System components include evaporator, expansion
valve, receiver-drier, control panel and condenser. A dual-pressure
switch includes a high-pressure cut-out switch and a low-pressure cut-
out switch.
Control panel includes 3 rotary knobs over 2 push buttons.
See Fig. 1. Left knob controls the fan and increases fan speed when
turned clockwise. Center knob is the temperature control and increases
heat by turning clockwise. Right knob controls air distribution.
The 2 push buttons are ON/OFF switches controlling A/C. Left
button controls normal A/C (outside air). Right button gives maximum
A/C using recirculating air. See Fig. 1.
