Operating modes

You can use your appliance in air extraction mode or
circulating-air mode.
The saturation indicator must be adjusted to the selec-
ted operating mode and the filters used.
4.1 Air extraction mode
The air which is drawn in is cleaned by the grease fil-
ters and conveyed to the exterior by a pipe system.
The air must not be discharged into a
flue that is used for exhausting fumes
from appliances burning gas or other
fuels (not applicable to appliances that
only discharge the air back into the
room).
¡ If the exhaust air is to be conveyed
into a non-functioning smoke or ex-
haust gas flue, you must obtain the
consent of the heating engineer re-
sponsible.
¡ If the exhaust air is conveyed
through the external wall, a tele-
scopic duct should be used.

If cooking produces large amounts of steam, select a
higher fan speed in good time.
Switch the appliance off when you are not using it.
Switch off the lighting if you no longer require it.
Clean or replace the filters at regular intervals.
Put the cooking lid on.
4.2 Air recirculation mode
The air which is drawn in is cleaned by the grease fil-
ters and an odour filter, and conveyed back into the
room.
¡ The odours are distributed around the room less.
¡ The appliance does not consume any energy.
¡ The lighting does not consume any energy.
¡ The effectiveness of the filters is retained.
¡ The cooking vapours and condensation are re-
duced.
To bind odours in circulating-air mode,
you must install an odour filter. The dif-
ferent options for operating the appli-
ance in circulating-air mode can be
found in our catalogue. Alternatively,
ask your dealer. The required accessor-
ies are available from specialist retail-
ers, from customer service or from the
Online Shop.
