13-34. 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
13-12 for the switch
locations.
13-35. CONDENSER ASSEMBLY RIGGING INSTRUCTIONS. (Refer to Figure 13-12.)
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:
a. Adjust
open limit
switch (5)
to open the
condenser
door (8) 5.00
± .50 inches
when
measured from the leading edge of the door to the fuselage skin.
b. 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.
c. With the
door fully closed adjust the "CLOSED"
limit switch (6) so that
the
actuator (1)
travels an additional .12 of an inch
after the door is fully closed, this
is
necessary
to preload the mechanism. Refer
to Figure 13-12, View A-A.
d. Cycle the
assembly several
times to be certain
it operates properly
without binding.

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.
a.
Remove the necessary access
panels and discharge
system.
b.
Remove the capillary coil from the
outlet line. (Do not kink the capillary
tube.)
