Grilles
The grilles have to be cleaned regularly to ensure
the constant and reliable operation of the
ventilati on system and for your own health.
Make sure that the setting of the system (air
flow) is not changed when you clean the grilles.
The valve could be turned by accident and this
would mean that the opening becomes larger or
smaller. Each grille should be placed back in the
same duct opening in the same room from which
it was removed.
Filters
The heat recovery unit and the extractor have
filter s. The filters prevent the contamination of
the ventilation, guarantee years of correct
operati on and ensure that clean air is blown into
your home. This is very important for your health.
Check and clean the filters regularly (a few times
a year) and replace the filters when necessary.
This ensures the home is ventilated sufficiently at
all times. The filters can be cleaned manually by
washing them.
Cleaning grilles without filters
Grilles without filters can be taken out of the
duct opening (twist to the left). Before you clean
the grille in warm water (with detergent), remove
the foam plastic ring. After cleaning, the grille
can be replaced in the duct opening with a twist
to the left. Always make sure you replace a grille
in the same room.
