3.Once the mounting plate has been attached to the wall, the unit can be installed. The unit should be aligned with the breather tube (7) pointing down. The electrical chase should be guided through the hole in the motor compartment. The horizontal support channels (8) should slide over the mounting angle clips (10) on the mounting plate until the holes in the windband and clips are aligned. Replace fasteners (9) and tighten. Wiring now can be done. Consult local code authorities for your specific requirements.

4.During shipping, wheel position may shift. Alignment should be as shown above (centered in the inlet) and can be accomplished by loosening the fasteners (11) located in the motor compartment. For belt drive units, additional vertical alignment can be accomplished by loosening the four fasteners on the drive frame support angles, and the 2 fasteners that hold the L-brackets to the support angles on top (13). Also, horizontal alignment can be made by loosening the bearings from the bearing plate. Removal of the entire power pack (motor, drives and wheel) for maintenance or cleaning can be accomplished by removing the breather tube (12) and fasteners (11).

Pre-Starting Checks

1.Check all fasteners and setscrews for tightness. The wheel should rotate freely and be aligned as shown in figure 7.

2.Wheel position is preset and the unit is test run at the factory. Movement may occur during shipment and realignment may be necessary.

3.Only CW unit - Centering height alignment can be accomplished by loosening the set screws in the wheel and moving the wheel to the desired position.

4.Only CWB unit - Centering can be accomplished by loosening the bolts holding the drive frame to the shock mounts and repositioning the drive frame.

5.Only CWB unit - Wheel and inlet cone overlap can be adjusted by loosening the setscrews in the wheel and moving the wheel to the desired position.

6.Only CWB unit - Fan RPM should be checked and verified with a tachometer.

7.Check wheel rotation (viewing from the shaft side) by momentarily energizing the unit. Rotation should be clockwise and correspond to the rotation decal on the unit, see figure 8. If wheel rotation is incorrect reverse two of the wiring leads or check motor wiring for single phase.
