screws, flat washers and lock-washers through the bottom of the frame.
a. Description. The condenser fan guard is mounted near the middle of the rear surface of the air conditioner.
The guard is fabricated from heavy-weight expanded metal mesh mounted in a circular sheet-metal frame. The attaching
screw holes in the frame are purposely arranged in an unsymmetrical pattern. so that the fan guard can be installed in only
one way. This installation is necessary to orient the angle of the expanded metal so that hot exhaust air will be deflected
upward, away from the condenser coil intake.
b. Removal. Remove eight screws and lockwashers from the frame
of the fan guard, and remove the guard.
Dry cleaning solvent (Fed. Spec PD-680) used to clean parts is potentially dangerous to personnel and
property. Do not use near open flame or excessive heat. Flash point of solvent is 100F to 138F (38C
c. Cleaning. Agitate the fan guard in detergent solution or dry cleaning solvent (Fed Spec P-D-680). Wipe or
d. Inspection/Repair. Inspect for broken, cut or deformed metal, and for broken tack-welds between frame and
screen. Straighten minor deformation being careful to avoid flattening the screen. Replace the guard if broken or cut.
e. Installation. Position the condenser fan guard on the air conditioner so that all screw holes match. Secure
with eight screws and lockwashers.
a. Description. The two-speed fan motor support is a welded fabrication of tubing and formed sheet metal
which supports the rear end of the motor. It is attached to the back panel with rivet nuts which are used to attach the
condenser fan guard to the unit. The back panel is attached to the sides of the casing with blind rivets.
b. Removal. Remove the back panel and motor support assembly from the air conditioner as directed in the
