WARNING
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 or without the
air conditioner operating. Presence of CO2 shall not exceed 1 part in
20,000.
14-34. 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 14-11 for the switch locations.
14-35. CONDENSER ASSEMBLY RIGGING INSTRUCTIONS. (Refer to Figure 14-11.) The condenser
assembly is actuated by an electric motor through bellcranks, push rods and limit switches.
It is necessary for the condenser door to fit flush with the fuselage skin and with increased force along the
forward edge. The following steps will help accomplish this requirement: (Refer to Figure 14-11.)
a.
Adjust open limit switch (5) to open the condenser door (8) five inches when measured from the
