TROUBLESHOOTING

PROBLEM
The fan seems louder than
it should be.
The fan is not clearing the
humidity from the room.
POSSIBLE CAUSE
The CFM is too great for the space.
The damper is damaged or not working properly.
The bend in the duct is too close to the fan
discharge.
The fan discharge is reduced to fit a smaller duct.
The fan body is not attached securely.
There is insufficient airflow intake in the room.
There is insufficient CFM.
NOTE: Using a tissue is not the correct 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.

SOLUTION
Be sure the CFM rating on the fan matches the
square footage of your room.
Check the 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 the
duct within 18 in. of the fan discharge.
Use the recommended size ducting to reduce fan
noise.
Be sure the fan is securely attached to the ceiling
joists.
Be sure a door or window is slightly ajar or open to
allow airflow. The fan is not able to draw air out of
the room without enough airflow.
Be sure the CFM rating of the fan matches the
square footage of your room.
