Start-Up
Ensure free rotation of the prop. Turn on the fan. In variable
speed units, set fan to its lowest speed and inspect for the fol-
lowing:
• Direction of rotation
• Excessive vibration
• Unusual noise
• Bearing noise
• 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.
Inspection
Inspection of the fan should be conducted at the first 30
minute, 8 hour and 24 hour intervals of satisfactory opera-
tion. During the inspections, stop the fan and inspect as per
the following:
30 Minute Interval
Inspect bolts, setscrews and motor mounting bolts. Adjust
and tighten as necessary.
8 Hour Interval
Inspect bolts, setscrews and motor mounting bolts. Adjust
and tighten as necessary.
24 Hour Interval
Inspect bolts, setscrews and motor mounting bolts. Adjust
and tighten as necessary.
