BEFORE BEGINNING
MAINTENANCE WORK
The safety switch automatically turns off the power when
the upper door of the unit is opened. Always disconnect

maintenance.
OPENING AND CLOSING THE DOORS

Turn the latches to open the upper door of the
ventilation unit.
2.
Lift off the door.
NOTE
Caution: the door is heavy.
3.
Open the lower door of the ventilation unit by
undoing the finger screws.

Lift the lower door off.

There are two unit models, left- (L) and right-handed (R).

FILTERS
When the maintenance reminder becomes activated,
check the cleanliness of the filters and replace them if
required.
The Adroit 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 Airflow filters ensures that the ventilation
unit remains in top condition, giving the best results.
