REMOVAL AND INSTALLATION OF THE CV SERIES POWER VENTER MOTOR

ASSEMBLY

EMOVAL

1. Remove the motor enclosure cover by loosening the four screws. (See Figure 14)

2. Disconnect the conduit connector from the motor conduit box by loosening the

screw on the side of the connector. Pull the wires and wire nuts out of conduit box

hole and remove the wire nuts. NOTE: Wiring disconnection may not be necessary

for inspection and/or cleaning only. (See Figure 15)

3. Remove the three or four nuts securing the motor assembly, and pull the motor

assembly straight off of the unit. (See Figure 16)

4. Clean off any build-up inside the blower wheel housing and the blower wheel.

CAUTION: Avoid applying excess pressure on the blower wheel when cleaning

off any build-up of material. This will cause an imbalance of the blower wheel,

which will result in excessive vibration and premature motor failure.

NSTALLATION

1. Align the holes in the circular cover plate with the holes in the motor mount

bracket on the motor assembly. (See Figure 16)

2. Slide the motor assembly onto the protruding threaded studs on the power

venter body with the exhaust chute pointing downward, and replace the four

nuts securely to the threaded studs. (See Figure 16)

3. Re-attach wires and wire nuts to the motor wiring and reinstall the conduit

connector, firmly tightening the screw on the side of the connector.

4. Install the motor cover with the side louvers pointing downward.
