HOW TO CLEAN THE AIR FILTER
Clean the air filter when the display shows “

(TIME TO CLEAN AIR FILTER).
Increase the frequency of cleaning if the unit is
installed in a room where the air is extremely
contaminated.
(As a yardstick for regulating yourself, consider
cleaning the filter once every two weeks.)
1. Open the front panel.
Place your fingers on the panel protrusions on
the left and right sides of the main unit and open
until the panel stops.
2. Pullout the air filter.
Push up the tab in the center of the air filter
slightly then pull out in a downward direction.

replacing it once every 3 years.

lightly with water.
• If it is very dirty, soak it for 10 to 15 minutes in
water mixed with a neutral cleaning agent.
• After washing, shake off remaining water and
dry in the shade.
• Since the material is made out of paper, do not
wring out the filter when removing water from it.
