d. Installation. Slide filters into slots, with cutoff corner toward left front. Position covers on air conditioner, and
secure with attached panel fasteners.
4-23. Condenser Air Inlet Screen.
The condenser air inlet screen prevents dust and airborne debris from being sucked into the condenser air intake.
The screen must be kept clean at all times while the air conditioner is operating on the cooling cycle. Clogging will reduce
the air-flow through the condenser coil, and will seriously reduce efficiency of the unit.
a. Removal. Remove 12 screws from the top and bottom edges of the air inlet screen frame, and remove the
screen.
b. Inspection. Inspect screen for broken or displaced wires, cut or ruptured screen mesh, and bent or deformed
frame.
c. Servicing. Clean the screen by agitating in a bath of detergent solution. Use a stiff brush if necessary to dis-
lodge stubborn deposits of dirt.
d. Installation. Position the screen on the air conditioner, and secure with 12 screws through the top and bottom
edges of the frame.
4-24. Back Panel and Motor Support.
The back panel and motor support assembly is a welded assembly. If the assembly sustains major damage, it must
be replaced. To gain access to the motor support assembly, it is necessary to remove several panels and assemblies
from the air conditioner. Proceed as directed in the following steps:
a. Removal of Air Conditioner Cover. With the cover rolled down, remove 12 screws and washers from the
edges, and two turn button fasteners from the top. Carefully work the cover off the mounting flange and retain for re-
assembly if it is in serviceable condition.
b. Removal of Deflector Door. With the deflector door closed, remove six screws from the hinge at bottom of
door. For model CV-60-5/6-08 remove eight screws from the hinge at bottom of door. With door open, remove two
screws and nuts from the front of the shelf bracket at each end of the door. Retain for re-assembly if the door is in serv-
iceable condition. For model CV-60-5/6-08 drill out rivets from the front of shelf bracket at each end of the door.
c. Removal of Fan Guard. Remove six screws from the attaching loops of the fan guard, and pull off the guard.
d. Removal of Fan Impeller. With the fan guard off, loosen the two setscrews in the fan hub and pull off the im-
peller. Use a gear- or pulley-puller if necessary to remove the impeller from the motor shaft.
e. Removal of Front Panel. Unscrew four panel fastener screws from the front panel (three along top edge, and
one near the center of the panel.) Remove the panel by pulling the top outward and upward.
f. Removal of Junction Box and Control Panel Assembly.
WARNING
Disconnect power input cable from the air conditioner before doing maintenance
work on the unit. The voltage used can be lethal.
(1) Disconnect electrical cables from control panel and junction box.
CAUTION
Be careful to avoid kinking or pinching the capillary tube which connects the control
panel assembly to the temperature control thermostat sensing bulb.
(2) Remove four screws from the corners of the control panel assembly mounting feet, and move control panel
assembly out of the way.
