MAINTENANCE INSTRUCTIONS
Fans
Check the cleanliness of the fans when carrying out maintenance for
the filter and the heat recovery cell. Clean the fans if needed. The
fans can be removed from the unit for cleaning. The fan blades can
be cleaned with compressed air or with a brush. Do not remove or
move the balancing pieces on the fan blade.
Detaching supply air filter (A)
Before detaching the supply air fan, you must remove the F7 fine filter
(C). To remove the F7 fine filter, pull it out. The fan is attached to the
fixing plate with a butterfly nut. Detach the butterfly nuts and lift the
fan off. Finally, disconnect the quick coupling of the fan conductor.
Condensing water
During the heating season, humidity of extract air condenses into
condensing water. Water formation may be abundant in new
buildings or if ventilation is low compared to the humidity build-up
caused by the residents. Condensing water needs to flow out from
the ventilation unit without hindrance. In carrying out maintenance,
e.g. in autumn before the beginning of the heating season, make
sure that the condensing water outlet (L) in the bottom tank is not
clogged. You can check it by pouring a little water in the tank. Clean
if needed. Do not let water flow into electrical devices.
Detaching extract
air filter (B)
The fan is attached to the
fixing plate with a butterfly
nut. Detach the butterfly nuts
and lift the fan out. Finally,
disconnect the quick coupling
of the fan conductor. If you
use water for cleaning the unit
or parts of it, do not let it enter
the electrical parts.
Cooker hood
Cooker hood grease filter
The grease filter of the cooker hood has to be cleaned 1 to 2 times
a month, depending on how much the hood is used. The grease
filter can be washed with hot water and washing-up liquid or in a
dishwasher. Remove the grease filter by pressing the quick couplings
(1) on the bottom plate of the hood open, letting the bottom plate go
in the down position and removing the filter from its clips (2).
