□
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.
