BEFORE BEGINNING
MAINTENANCE WORK
The safety switch (S) automatically turns off the power
when the door of the unit is opened.
WARNING
Always disconnect the power plug before starting
the ventilation unit maintenance.
There is a left-handed (L) and right-handed (R) version of
each model. The figure shows the right-handed model.
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.
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.
CAUTION
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.
TIP
Using original Vallox
filters ensures that the
ventilation unit remains
in top condition,
giving the best results.
