Depending on the model you purchased, the cooktop
extractor can be operated as an exhaust air or an
recirculating air version.
Exhaust mode
The air extracted is cleaned by the stainless steel grease
filter and released outside through a duct system.
The exhaust air must not be expelled into:

a smoke or exhaust gas flue that is in operation

a shaft used for the aeration of rooms where fireplaces
are installed.
If the exhaust air is to be directed into a smoke or
exhaust gas flue that is not in use, the installation must
be checked and approved by the responsible heating
engineer.
Recirculation mode
The air extracted is purified by the grease filter and an
activated charcoal filter and fed back into the room in
which the appliance is installed.
To prevent odours in recirculation mode, an odour
filter must be used. For hygiene and health reasons,
the activated charcoal filter must be replaced at
the recommended intervals (see the Cleaning and
maintenance section).
INFO In recirculation mode, ensure sufficient ventilation
and aeration to expel humidity.
