MAINTENANCE MANUAL
INSTALLATION OF CONDENSER.
I Install the condenser core to the frame assembly with the hose fittings forward and up.
2 Place the condenser and frame assembly to the fuselage frame mounting bracket and insert the (8)
screbs into the piano hinge.
3 Attach the side hinges and actuating rod and rig per Condenser Assembly Rigging Instructions
4. Seal and couple the hose fittings (seal with Loctite refrigerant sealant applied to flanges only).
5. Adjust the condenser in accordance with Condenser Assembly Rigging Instructions.
6. Seal all around forward cover panel (and aft cover panel if removed) with Permagum Bead No. 576
purchased from Prestolite Engineering Company. (See Figure 21-14.)
-NOTE-
Whenever it is necessary to remove and replace the cabin rear panel,
it should be replaced and sealed in the original manner. If it is not,
because of the low pressure area in the cabin, exhaust gases may seep
into the cabin.
- WARNING -
Make a carbon monoxide test on ground and in flight with and
without the air conditioner operating. Presence of C02 shall not
exceed I 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 21-14 for the switch locations
CONDENSER ASSEMBLY RIGGING INSTRUCTIONS. (Refer to Figure 21-14.)
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:
1. Adiust open limit switch to open the condenser door 5.00 + - .50 inches when measured from the
leading edge of the door to the fuselage skin.
2. Adjust side push rods so that a vertically measured gap of .16 of an inch exists along the trailing edge
of the door at the instant the forward edge of the door becomes flush with the fuselage skin.
3. With the door fully closed adjust the "CLOSED" limit switch so that the actuator travels an
additional .12 of an inch after the door is fully closed, this is necessary to preload the mechanism. (Refer to
Figure 21-14. View A-A.)
4. Cycle the assembly sevral times to be certain it operates properly without binding
