WARNING Before servicing or cleaning unit,
switch power off at service panel and lock the service
disconnecting means to prevent power from being switched on
accidentally. When the service disconnecting means cannot be

Cleaning and Maintenance
To Clean
For quiet and efficient operation, long life and attractive
appearance, remove grille and vacuum interior of unit with a
dusting brush attachment.
The motor is permanently lubricated and never needs oiling. If
the motor bearings are making excessive or unusual noises,
replace the motor.
Troubleshooting
Symptom: The fan does not run.
• Check for an open fuse or circuit breaker in the building’s
service panel.
• Check that the plug-in connection for the motor is seated
firmly in place.
• Check that the blower wheel spins freely.
Symptom: The fan runs erratically.
• Check that the blower wheel is firmly attached to the motor
shaft and both spin freely.
Symptom: The fan seems noisy.
• Check that the back draft damper in the fan’s duct connector
pivots freely. Screws used to attach the ducting to the duct
connector may be preventing the damper from opening.
• Check that the back draft damper in the wall or roof cap pivots
freely. These dampers are sometimes mistakenly painted shut
or obstructed by bird and insect debris.
