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 yourself, consider cleaning the filter once a half
year.)
If dirt becomes impossible to clean, change the air filter. (Air filter for
exchange is optional.)
1.
Open the suction grille.
Grip the suction grille on one side, and open by pulling toward
yourself while holding it up.
2.
Remove the air filters.
Push the air filters operation section with both hands in the
direction indicated by the arrow, undo the air filter clips, and take
out downward.
3.
Clean the air filter.
Use a vacuum cleaner or wash the air filter with water.
When the air filter is very dirty, use a soft brush and neutral
detergent.
Remove water and dry in the shade.
