Warning

The safety switch automatically turns off the power when the upper door of the Vallox ventilation unit is opened. Always disconnect the Vallox ventilation unit from the mains before starting maintenance.

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. Do not remove or move the fan blade balancing weights.

Important

The fans are extremely sensitive to external shocks. It is recommended that the fans be cleaned in place, i.e. without attempting to remove them.
