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.
