No, caring for an enthalpic heat exchanger is no more demanding than for a standard one. Maintenance is described in the user manual and in our video guide. In short: first vacuum the exchanger with a soft brush attachment, then rinse it with clean water (max. 50 °C). Never use compressed air or a pressure washer.

After rinsing, allow all water to drain completely. Remaining moisture can be carefully blown out with a regular hairdryer, but always use cold air only. Once the exchanger is completely dry, place it back into the unit in the same orientation as before removal.

We do not recommend using chemicals for cleaning. Only if disinfection is absolutely necessary may a weak solution of peracetic acid be used, followed by very thorough rinsing with clean water.
