*Damper motors may be available in 115, 230 and 460 volt models. The
damper motor nameplate voltage should be verified prior to connection.
**A transformer may be provided in some installations to correct the
damper motor voltage to the specified voltage.

Pre-Start Checks

L 2
1. Lock out all the primary and secondary power sources.
2. Inspect and tighten fasteners and setscrews, partic-
ularly fan mounting and bearing fasteners. Refer to
Torque Chart.
3. Inspect belt tension and pulley alignment. Refer to Belt
and Pulley Installation, page 5.
4. Inspect motor wiring. Refer to Wiring Installation.
5. Ensure belt touches only the pulleys.
6. Rotate the wheel to ensure it rotates freely.
7.
Ensure fan and ductwork are clean and free of debris.
8. Close and secure all access doors.
9. Restore power to fan.
Start-Up
Turn on the fan. In variable speed units, set the fan to its
lowest speed. Inspect for the following:
• Direction of rotation
• Excessive vibration
• Unusual noise
• Bearing noise
• Improper belt alignment or tension (listen for squealing)
• Improper motor amperage or voltage
and
If a problem is discovered, immediately shut the
1
fan off. Lock out all electrical power and check for
the cause of the trouble. Refer to Troubleshooting
on page 7.
