purchased from Prestolite Engineering Company. (See Figure 21-17.)
Whenever it is necessary to remove and replace the cabin rear
panel, it should be replaced and sealed in the original manner to
prevent exhaust gases from entering the cabin. After removing
and replacing the rear panel, conduct a carbon monoxide test on
ground and in flight with and without the air conditioner
operating. Presence of CO2 shall not exceed 1 part in 20,000.
CONDENSER DOOR ACTUATOR.
The actuator is on a bracket mounted between two bulkheads in the tail cone. It is coupled to the condenser
assembly through a bellcrank mounted to a bracket on the bulkhead aft of the condenser. The actuator travel is
controlled by two limit switches. Both the up and down switches are located on the actuator. (Refer to Figure
21-17 for the switch locations.)
