Operation Checklist
Check fan mechanism components:
□ Nuts, bolts, setscrews are tight.
□ Mounting connections are properly made and
tightened.
□ Bearings are properly lubricated.
□ Wheel, drives and fan surfaces are clean and
tightened.
□ Rotating assembly turns freely and does not rub.
□ Drives on correct shafts, properly aligned, and
properly tensioned.
Check fan electrical components:
□ Motor is wired for proper supply voltage.
□ Motor was properly sized for power of rotating
assembly.
□ Motor is properly grounded.
□ All leads are properly insulated.
Trial “bump”:
□ Turn on power just long enough to start assembly
rotating.
□ Check rotation for agreement with rotation arrow.
□ Listen for any unusual noise.
Run unit up to speed:
□ Bearing temperatures are acceptable (<200°F) after
one to two hours of operation.
□ Check for excess levels of vibration. Filter in readings
should be 0.15 inches per second or less.
After one week of operation:
□ Check all nuts, bolts and setscrews and tighten if
necessary.
□ Re-adjust drive tension if necessary.
Verify that proper safety precautions have been
followed. Electrical power must be locked off.
