Filter Performance

• Pay careful attention to clogging in the filter. A clogged filter will

prevent the Fan from providing a cooling effect.

Replacing the Filter

1. Turn OFF the power, wait approximately one minute, and then

open the cover. Remove the filter, replace it with a new filter, close

the cover, and then firmly tighten the handle screw. This

completes the filter replacement.

2. As a general guide to the replacement frequency, check the color

of the filter regularly and replace it when the color shows a

noticeable change.

3. It is recommended that the filter be replaced soon after the color

changes noticeably in order to maintain the Fan's performance.
