CHANGING 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. To select
and order filter packages, please go to: filters.vallox.com
To replace the filters:

2. Open the upper door of the unit.
3. Remove the old filters (A, B, C) and discard them.
