Cleaning an enthalpy heat exchanger consists of a few simple steps:

1. First, vacuum the exchanger using a vacuum cleaner with a soft brush attachment.
2. Then rinse it with clean water (max. 50 °C).
3. Do not use compressed air or a pressure washer.
4. After rinsing, let all water drain out naturally.
5. Remaining moisture can be removed with a hair dryer – only using cold air.
6. Once completely dry, insert the exchanger back in the same orientation.

Chemical cleaning agents are not recommended. Only if disinfection of the exchanger is necessary, a weak peracetic acid solution (CH₃CO₃H) at a concentration of 0.1–0.2% may be used and must then be thoroughly rinsed with clean water.
