- annual visual inspection of the heat exchanger also cleaning if required.
- annual cleaning of inside.
- annual check and cleaning of condensation run-off and the siphon.

- With the assistance of another person, carefully and evenly (in parallel) pull the heat exchanger unit out of the ventilation unit.
- Carefully clean the heat exchanger with lukewarm water. Allow it to dry completely.
- Wipe off the interior walls of the ventilation unit with a cleaning cloth.
- Carefully slide the fully dried heat exchanger as far as it will go into the housing.
- Reconnect the bypass motor.
- Screw the partition plate back onto to the heat exchanger.
- Close the small front door.

- Switch the mains fuse on.
- Switch on the ventilation unit at the room air control.
Do not damage sealing strip when pulling out/sliding in the heat exchanger.
