10.2.1 To clean the air filter
When to clean the air filter:
▪ Rule of thumb: Clean every 6 months. If the air in the room is extremely
contaminated, increase the cleaning frequency.
▪ Depending on the settings, the user interface can display the "Time to clean
filter" notification. Clean the air filter when the notification displays.
▪ If the dirt becomes impossible to clean, change the air filter (= optional
equipment).
How to clean the air filter:
1 Remove the filter fixing screw. In case of installation without duct on the
suction side, remove the filter fixing screw.
2 Remove the air filter. Pull its cloth upward (in case of rear suction) or
backward (in case of bottom suction).
