Replacing the filters

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.

There are two unit models, left- (L) and right-handed (R). In the right handed version, outdoor air blows into the unit from the right side of the centre line as shown in the instructions. In the left-handed version, outdoor air blows into the unit from the left side. Also the position of the filters, HR cell bypass damper, and heating resistor is mirrored in the left-handed model.

Important:
If the power cord is damaged, the manufacturer, its service representative or other person with similar qualifications must replace it to avoid danger.
Note:
Vallox TSK Multi 50 MV: The service space in front of the unit must be at least 530 mm.

Vallox TSK Multi 80 MV: The service space in front of the unit must be at least 600 mm.

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
