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.
For framing dimensions, refer to rough-in opening height and width shown in the specifications above.
Position the fan for desired airflow. Air will discharge on the side of the fan facing the propeller.
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.
Maintenance
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.
