Detailed information
The ventilation unit is equipped with supply and extract air filters.
The supply air filter ensures the quality of the supplied air and protects the ventilation unit from outdoor dust and insects entering it (M5, Carbon G4, F7 filtration classes).
The extract air filter protects the ventilation unit from indoor dust and insects entering it (M5 filtration class).
Filter replacement procedure:
- Use the controller to switch off the ventilation unit and make sure that the fans have completely stopped.
- Open the compartment of the ventilation filter you plan to replace by removing the cover marked with the “OXYGEN” symbol.
- Pull out the dirty ventilation unit filter by the handle.
- Insert the new ventilation unit filter in the airflow direction indicated on the filter.
- Close the filter compartment by closing the cover and make sure it fits tightly against the ventilation unit casing.
- Switch on the ventilation unit.
