5.3 Unit Maintenance
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.
