CORRECTIVE ACTION
Be sure the CFM rating on the fan matches
the size of your room
Check damper to ensure it is opening and
closing properly. If the damper has become
damaged, please call Customer Service
Be sure you do not have any sharp bends in
duct closer than 18 in. to the fan discharge
Use recommended size ducting to reduce fan
noise
Be sure the fan is securely attached
to your ceiling joists
Be sure a door or window is slightly ajar or
opened to allow airflow. The fan is not able
to draw air out of the room without enough
airflow to draw from
Be sure the CFM rating on the fan matches the
requirements for your room size
NOTE: Using a tissue is not an accurate
method for determining if the fan is operating
properly. If the fan clears steam from the room
within approximately 15 minutes of completing
your shower, then the fan is operating properly
