ventilator.

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 

locked, securely fasten a prominent warning device, such as a 

tag, to the service panel. 

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.
