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.
When the maintenance reminder becomes activated, check the cleanliness of the filters and replace them if required.
The Vallox ventilation unit has three air filters:
-
Coarse filter for supply air filters insects, heavy pollen and other relatively large foreign objects out of the outdoor air.
-
Fine filter for supply air filters microscopic pollen and dust particles out of the supply air.
-
Coarse filter for extract air filters the extract air and keeps the heat recovery cell clean.
The filter replacement interval depends on the ambient dust concentration. It is recommended that the filters be replaced every spring and autumn, or at the very least once a year.
Note
Using original Vallox filters ensures that the ventilation unit remains in top condition, giving the best results.
To replace the filters:
-
Disconnect the ventilation unit from the mains electricity supply.
-
Open door of the ventilation unit by undoing the finger screws.
-
Lift the door off.
Caution

-
Close the door of the unit. Ensure that the safety switch catch of the door is engaged (S), allowing the unit to be turned on.
-
Plug the ventilation unit back into the mains.
The filters have now been successfully replaced.
