17.2.1 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 AIR
FILTER notification. Clean the air filter when the notification is displayed.
▪ If the dirt becomes impossible to clean, change the air filter (= optional
equipment).
