CHANGING THE FILTERS
The Adroit ventilation unit has three filters:

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 .

1 . Disconnect the ventilation unit from the mains
electricity supply .
