Fan Motor Inspection & Maintenance
•
Clean the outside of the motor at least quarterly to ensure proper motor cooling.
•
After prolonged shutdowns, check the motor insulation with an insulation tester prior to restarting the motor.
•
Check the motor voltage and current following start-up and every three months while in operation.
Fan Shaft Bearing Inspection & Maintenance
•
For all units ordered with the BALTIDRIVE
®
Power Train, two pillow block ball bearings support the fan shaft and are
provided with extended lube lines as standard on the
Vertex™ Evaporative Condenser. Each bearing is e
quipped with a
lubrication fitting and a locking collar to keep out moisture.
•
Only lubricate the bearings with a manual grease gun or BAC’s optional Automatic
Bearing Greaser. Do not use high-
pressure grease guns since they may rupture the bearing seals or the extended lubrication lines.
•
Only lubricate the bearings with one of the following compatible water-resistant greases which are suitable for ambient
temperatures ranging from -65ºF (-53.9ºC) to +250ºF (121.1ºC).
