Replacing the filters

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 particle 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. Selection and ordering of filter packages: valloxsuodattimet.fi
Note: The service space in front of the ventilation unit must be at least 500 mm.

To replace the filters:

  1. Disconnect the ventilation unit from the mains electricity supply.
  2. Lift off the door cover panel. Undo the unit’s mounting screws (4 mm hexagon).
  3. Lift the door off.
  4. Remove the old filters (A, B, C) and discard them.
    Note: The door is heavy.
  5. Install the new filters (A, B, C).
  6. 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.
  7. Plug the ventilation unit back into the mains.
The filters have now been successfully replaced.
