Care and Maintenance

To maintain optimal performance, keep the fans clean. Canned air works well. If the fans are used outdoors or in a dusty environment is recommended to clean the fan blades as needed to keep clean.


The fan will not start:

1. Check the power connections.
2. Is the light on the power switch on? If not check power. If on and the fans are not spinning see #3.
3. Turn the fan blade by hand to see if they are stuck. They should be free moving. If this starts the fan it is likely the fans need maintenance.

The fan is making noise:

1. Check for anything that could be rubbing against the fan blade.
2. Make sure the fan blades are clean. Dirty fan blades can make noise.

If the above steps do not solve the problem, contact our friendly customer service for assistance.
