3.3.1.2 Resetting the filter maintenance display
The filter maintenance indicator must be reset after each air filter change in order to restart the filter maintenance cycle
monitoring. To do this, touch the (+) and (-) keys on the control panel simultaneously for three seconds. The flashing red
filter maintenance LED will go out.
NOTE
As part of filter maintenance for units with a second room connection, check any other air filters that may be present in
the ventilation system.
Unit maintenance
Maintenance of the unit is limited exclusively to the external surfaces of the ventilation unit and the operating surface of
the control panel, which should be wiped down from time to time using a soft, damp cloth – never just wipe dry.
WARNING
Risk due to electric shock
Disconnect the ventilation unit from the power supply before cleaning.
Make sure that no moisture can enter the inside of the housing during cleaning.
Never use a high-pressure cleaner, steam cleaner or steam jet.
NOTE
Never use flammable, acidic, corrosive or abrasive cleaning agents.
What should I do in case of a malfunction?
In the event of a fault message (indicated by the LED fault lighting up continuously), contact customer service.
Information about the type of your ComfoAir 70 can be found on the type label, which is located under the design cover of
the unit.
NOTE
As a reaction to a fault status, the fans are shut down and the shutters automatically closed.
As soon as there is a disconnection, the apartment will no longer be mechanically ventilated. This may result in moisture
and mould problems in the room that requires ventilation.
