MAINTENANCE & TROUBLESHOOTING
Make sure the appropriate circuit breakers at the home’s electrical panel are turned OFF before servicing this fan.
There is no routine maintenance required for this fan other than making sure the fan assembly and gravity damper
are kept clean of any possible buildup of debris.
Blocking this fan’s exhaust can cause it to fail prematurely. Keep the area in front of the fan as unobstructed as
possible: no object should be closer than 24” to the face of the fan.
This fan has been factory tested. If problems are encountered, please take a few moments to run through the
following troubleshooting procedures before calling for assistance:
• If the fan does not turn on, check power to the unit and the wiring at both ends of the switch and the
fan-mounted junction box.
• If the damper fl aps do not open or close, visually inspect the damper for any debris obstructing their
movement.
If the suggestions above do not work, contact your retailer for further assistance.
