5.3.1 Filter screen cleaning
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) Removing the air filter from the duct.
(2) Cleaning the air filter.
Remove dust from the air filter using a vacuum cleaner and gently rinse
them in cool water. Do not use detergent or hot water to avoid filter shrinking or
deformation. After cleaning dry them in the shade.
Press the return air filter downward against the guide groove sponge. There
are two or three return air inlet filters.
(3) Replacing the air filter Reinstall the filter as before.
