Assure the fan is fastened securely in the opening to avoid excess “rattling” or vibration using proper fasteners.
Fasteners not included.
Refer to motor nameplate for wiring diagram.
Fan Installation
CAUTION
BEFORE OPERATING YOUR NEW FAN, CHECK BLADE FOR PROPER TORQUE, CHECK ALL
FASTENERS FOR TIGHTNESS AND ASSURE SCREENS AND/OR SHUTTERS ARE SECURELY
IN PLACE.
Periodic maintenance schedules should be set to assure reliability and performance of the fan. This maintenance
should included inspection of all
fasteners, propeller torque and proper cleaning of the complete fan assembly.
Check for excessive vibration while fan is running.
Periodically inspect and tighten all set screws and hardware.
Assure all mounting hardware, chains, etc. are properly secured.
Motors feature permanently sealed ball bearings and require no further lubrication.
The fan propeller should be periodically cleaned to assure proper balance and performance.
Grease pillow block bearings seasonally. Use caution not to apply too much grease as it may damage the seals.
Periodically check for proper belt alignment.
