MAINTENANCE
BEFORE BEGINNING
MAINTENANCE WORK
When you open the door of Vallox 096 MC, the safety
switch (S) cuts the power. Despite this, disconnect the
power supply plug anyway. Always disconnect the power
plug before starting maintenance on the Vallox 096 MC.
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 (A) filters insects, heavy
pollen and other relatively large foreign objects out of
the outdoor air.
• Fine filter for supply air (B) filters microscopic pollen
and dust particles out of the supply air.
• Coarse filter for extract air (C) filters the extract air
and keeps the heat recovery cell clean.
Using original Vallox filters ensures the best operation
of the ventilation unit and the best filtering results. 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.
HEAT RECOVERY CELL
Check that the heat recovery cell (D) is clean roughly
once a year when the filters are being replaced. Clean by
washing as required.
• Remove the sealing strip (E) above the heat recovery
cell in the direction of the arrow.
• Once you have removed the sealing strip, pull the
heat recovery cell out of the unit.
IMPORTANT! Handle the cell carefully! For example, do
not lift the cells by the layers. The cell layers are very thin
and easily damaged.
If the heat recovery cell is dirty, clean it by immersing it in
water containing a small amount of a mild detergent. Rinse
the heat recovery cell clean with a water spray. When all
the water has drained from between the layers, push the
cell recovery cell back in place. Lastly, push the sealing
strip back in place.
