Operation
Pre-Start Checks
1.
Lock out all the primary and secondary power sources.
2.
Ensure fasteners and setscrews, particularly those used for
mounting the fan, are tightened.
3.
Inspect belt tension and pulley alignment.
4.
Inspect motor wiring.
5.
Ensure belt touches only the pulleys.
6.
Ensure fan and ductwork are clean and free of debris.
7.
Inspect wheel-to-inlet clearance. The correct wheel-to-inlet
clearance is critical to proper fan performance.
8.
Close and secure all access doors.
9.
Restore power to fan.
Start-Up
Turn on the fan. In variable speed units, set fan to its low-
est speed and 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
NOTICE! If a problem is discovered, immediately shut
off the fan. Lock out all electrical power and check for
the cause of the trouble. Refer to Troubleshooting.

*Damper motors may be available in 115, 230 or 460 volt mod-
els. The damper motor nameplate voltage should be verified pri-
or to connection.
**A transformer may be provided in some installations to correct
the damper motor voltage to the specified voltage.
