f. Secure the end plate (11) to the stator (1) with four screws, tightened uniformly in increments. Attempt to turn
shaft by hand. If shaft does not turn freely, check assembly of end plate on stator, and adjust if necessary.
Install the motor in the air conditioner as directed in the following procedure: (See figure 4-7).
a. Position the flange end of the motor against the partition. Install four flat-head screws through the partition
and the holes in the comers for the motor's mounting flange. Place a bushing, a washer and a self-locking nut on each
screw, and tighten finger-tight.
Trial-fit resilient washers of the same thickness at first, then replace with different sizes if necessary to cen-
b. Place a lock washer. flat washer and bushing (flange end toward bolt head) on a socket-head shoulder bolt,
and partially insert bolt into hole in cross-bar. On top of cross-bar, place a resilient washer, large flat washer and small flat
washer between the cross-bar and the motor mounting foot. Push bolt and bushing up through the resilient washer, and
screw bolt into the motor mounting foot. Repeat assembly in the same order for the other mounting foot. Tighten both
bolts uniformly, and check for concentricity of impellers and openings. Adjust by replacing resilient washers with those
of a different thickness, as required. When satisfactory, tighten all mounting bolts, including the four bolts and nuts in the
corners of the flange.
c. Connect wiring harness plug, P9, to the receptacle on the motor's junction box. Temporarily connect power
to the air conditioner, and turn mode selector switch to VENTILATE . Check operation and direction of rotation of motor
at LO SPEED, and HI SPEED settings.
d. Place a lock washer and flat washer on each concave side of baffle. Place a spacer over each screw on the
convex surface, and tape in place with masking tape. Carefully position the convex side of the baffle against the mounting
bracket, and secure by tightening the four screws.
Do not hammer impeller onto shaft. Motor bearings would be damaged.
Dress out roughness on the shaft with a fine file, stone or abrasive cloth. Apply a coating of light oil to
e. Place key
in shaft keyway
and press condenser fan impeller onto
shaft. End of shaft should
be flush with face
of hub. Tighten both setscrews finger-tight. Starting with the keyway setscrew, tighten both set-screws to a fmal torque
of 78-82 pound-inches (898-945 gram-meters).
The fan guard is designed 50 that it can be installed only one way. All screw holes must match to permit
f. Place the condenser fan guard
on the air conditioner, and secure
it with eight screws and lock washers
g. Install key
in shaft keyway,
and press evaporator fan impeller onto
shaft. End of shaft should
be flush with the
hub face when installed. Tighten both setscrews finger-tight, then tighten to final torque of 78-82 pound-inches
(898-945 gram-meters) torque, starting with the keyway setscrew.
h. Place the air filter imposition, and install retaining strip with two screws.
i. Position evaporator air intake grille
on air conditioner, and secure
by turning the
studs 1/4 turn
