Inspection:
After unpacking your fan, carefully inspect for any damage that may have occurred during transit. Inspect for loose, missing or damaged parts.
If there is physical damage to any parts of the fan, a freight claim must be filed with the carrier. Check to assure that all bolts, screws and set
screws are securely tightened and have not become loose during transit. Retighten as required.

Troubleshooting Guide
Fan Installation Tips:
For framing dimensions, refer to rough-in opening height and width shown in the specifications on
the previous page.
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.
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.
Maintenance
Periodic maintenance schedules should be set to assure reliability and performance of the fan.
Check for excessive vibration while fan is running.
Periodically inspect and tighten all set screws and hardware—check torque on propeller.
Assure all mounting hardware is 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.
Note: Please contact the dealer/distributor where you purchased the fan from with any questions regarding the fan, manual
or if you are in need of replacement parts.
