Changing air filters
ATTENTION
- Change the air filters of the ventilation unit when the filter change indicator appears on the room air control (rapidly flashing LEDs).
- Never operate the ventilation unit without an air filter. The ventilation unit becomes dirty and unfiltered substances can enter the rooms.
- Generally, change the internal and external filters together.
- Only use original air filters with the prescribed filter class. Otherwise there is a danger to health from harmful substances that can accumulate in the air filter.
- Change the air filters regularly, after 6 months at the latest.
- Replace the air filters even after the ventilation unit has not been used for a longer period of time.
Change the air filters as described in the following chapters.
