7.35 AIR CONDITIONING. (continued)
The switches and temperature control are located on the lower right side (
of the instrument panel in the climate control center panel. The temperature
control regulates the temperature of the cabin. Turning the control
clockwise increases cooling; counterclockwise decreases cooling.
The fan speed switch and the air conditioning ON-OFF switch are
inboard of the temperature control. The fan can be operated independently
of the air conditioning; however, the fan must be on for air conditioner
operation. Turning either switch off will disengage the compressor clutch
and refract the condenser door. Cooling air should be felt within one minute
after the air conditioner is turned on.
NOTE
If
the system is not operating in
5
minutes. turn
the system OFF until the fault is corrected.
The fan switch allows operation of the fan with the air conditioner
(~
turned OFF to aid in cabin air circulation. LOWor
HIGH
can be selected to
direct a flow of air through the air conditioner outlets in the overhead duct.
These outlets can be adjusted or turned off individually.
A
condenser door light, located to the right of the tachometer,
illuminates when the door is open and is extinguished when the door is
closed. .
A circuit breaker on the circuit breaker panel protects the air
conditioning electrical system.
Whenever the throttle is in the full forward position, it actuates a micro
switch which disengages the compressor and retracts the scoop. This allows
maximum power and maximum rate of climb. The fan continues to operate
and the air will remain cool for about one minute. When the throttle is
retarded approximately
~
inch. the clutch will engage. the scoop will extend,
and the system will again supply cool, dry air.
