How to install the air clean filter
The air clean filter needs to be installed behind the anti-mold filter.
Open the front panel and remove the anti-mold filters, then install
the air clean filter in the position shown in the figure. After that,
remount the anti-mold filters and close the front panel.
How to clean the air clean filter
• In general, the filter should be sucked to remove dust in low fan
speed of a vacuum cleaner once every three months.
• If there is heavily grime on the filter, soak the filter in lukewarm
water with neutral detergent diluted 1:500 for 1 to 2 minutes then
wash it.
• Rinse the filter in clean water, then let it dry on the towel in room
temperature.
• Do not bend nor give excessive force onto the air clean filter.
• If the filter surface is heavily blocked with dirt or damaged,
replace it with new one. Purchase a replacement filter at your
local dealer. (model

Cleaning the main unit and remote controller
• Wipe clean using a soft, dry cloth.
• To remove stubborn dirt, moisten a cloth in warm water no hotter
than 40 °C, wring thoroughly, and then wipe.
• The front panel can be removed in order to wash it with water.
