CONDENSER ASSEMBLY RIGGING INSTRUCTIONS. (Refer to Figure 21-17.)
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 21-17.)
1. Adjust 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 the 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-
17.)
4. Cycle the assembly several times to be certain it operates properly without binding.
EXPANSION VALVE. (Refer to Figure 21-18.)
EXPANSION VALVE REMOVAL.
The expansion valve is located in the evaporator assembly between the receiver-drier and the evaporator
inlet. The capillary coil is attached to the evaporator outlet line.
