BEFORE BEGINNING MAINTENANCE WORK
When you open the device door, the safety switch (S) cuts the power. Despite this, disconnect the power supply
plug. Always disconnect the power plug before starting the ventilation unit maintenance.
There are two unit models, left- (L) and right-handed (R). The figure shows the right-handed model.
MAINTENANCE INSTRUCTIONS
MAINTENANCE
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:
•
Class G4 coarse filter filters insects, heavy pollen and other
relatively large foreign objects out of the outdoor air.
•
Class F7 fine filter filters microscopic pollen and dust particles
out of the supply air.
•
The coarse filter filters the extract air and keeps the heat
recovery cell clean.
The filter change interval depends on the ambient dust
concentration. It is recommended that the filters be changed
every spring and autumn, or at the very least once a year.
TIP
Using original Vallox filters ensures that the ventilation unit remains in
top condition, giving the best results.
