Incorrect dimension of the air duct.
Obstruction in the air duct.
The diameter of the air duct from hood
to wall-box inclusive should be 120 mm;
otherwise the capacity of the motor may
be decreased.
If you have installed a fly screen on the
wall-box, the air vent may be obstructed.
Check by removing the fly screen.
If the cover panel of the wall box is equip-
ped with firm and slanted slats, the air
vent may be obstructed. Check by remo-
ving the cover panel.
Install a cover panel with moveable slats,
which do not obstruct the air vent.
If the hood does not work properly and/or you can hear increased operating
noise, check the schedule below:
Check condition and cleanliness of the
filters.
Check if the air which is extracted by the
hood is replaced to avoid negativepressu-
re.
When you run your appliance in recir-
culating mode, check if the carbon filter
has been replaced on time (min. every 3-6
months).
If the appliance has a malfunction not no-
ted on the schedule or if you have checked
all items on the schedule but the problem
still exists, please contact the shop you
purchased the appliance at.
