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.
Troubleshooting
Problem
Potential Solution
The fan does not run
Check for an open fuse or circuit breaker in the building’s service panel.
Check that the two (2) plug-in connections for the Motor and the Control are seated
firmly in place.
Check that the Blower Wheel spins freely.
The fan runs erratically Check that the Blower Wheel is firmly attached to the Motor shaft and both spin freely.
The fan seems noisy
Check that the back draft damper in the fan’s Duct Connector pivots freely. Screws used
to attach the duct 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.
The fan does not properly
ventilate the room
For spot ventilation, turn both the master switch and the mode select switch ON to enable
the fan to run at the certified airflow rate.
For spot ventilation followed by continuous ventilation, increase the “TIME” setting of the
user-adjustable time delay.
For continuous ventilation, increase the “CFM” setting of the user-adjustable airflow rate.
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 Control Assembly and
Motor.
