Cleaning the fans

Warning:

Always disconnect the power plug before starting maintenance on the ventilation unit. The unit has no safety switch that would switch the power off when the door of the unit is opened.

Check the cleanliness of the fans when servicing the filters and the heat recovery cell. Clean the fans as required.

You can clean the fan blades with compressed air (wear protective goggles) or by brushing them gently.

Important:

The fans are extremely sensitive to external shocks.Handle the fan blades carefully.Do not remove or move the fan blade balancing weights.
