Operating modes

You can use this appliance in the air extraction or the
recirculation mode.

Air extraction

The air sucked in is cleaned by the
grease filters and is routed outdoors
through a pipe system.
Note: The extracted air must neither be discharged
into an operating smoke or waste gas chimney nor into
a shaft that serves to ventilate rooms where heat-
producing appliances are installed.
▯
The local chimney sweep's consent must be
obtained if the exhaust air is to be routed to a
smoke or waste gas chimney that is not in
operation.
▯
A telescopic wall duct should be used if the
exhaust air is routed through the outside wall.

Recirculation

The aspirated air is cleaned by the grease
filters and an activated charcoal filter and
is returned to the kitchen.
Note: You must install an activated charcoal filter to
bind odors in the recirculation mode. Refer to the
manual or ask your specialist dealer for details of the
various options for operating the appliance in the
recirculation mode. You can obtain the necessary
accessories from specialist dealers, from our after-
sales service or in the online shop.
