Filter replacement

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.

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/en

To replace the filter:

  1. Remove the cover panel (1e) at the top edge of the Vallox ventilation unit door by pulling the bottom edge of the plate outwards before lifting it off.
  2. Pull the insulation hatch (1l) of the supply air filter out by the handles on the hatch. Remove the cover hatch of the extract air filter (1m) by pulling the hatch from both ends.
  3. Remove the old filters (4a), (4b) and (4c) and dispose of them (do not dispose of the support mesh of the extract air filter).
  4. Install the new filters.
  5. Install the insulation door (1l) of the supply air filter by pressing its edges behind the surface plate of the door. The cover hatch (1m) of the extract air filter is installed so that both of its ends are against the door plate.
  6. Put the supply air filter cover panel (1e) back in place.
  7. Reset the maintenance reminder.
