Operating modes
This appliance can be used in exhaust-air mode or
circulating-air mode.
Exhaust air mode
The air which is drawn in is cleaned by
the grease filters and conveyed to the
exterior by a pipe system.
Note: The exhaust air must not be conveyed into a
functioning smoke or exhaust gas flue or into a shaft
which is used to ventilate installation rooms which
contain heat-producing appliances.
▯
Before conveying the exhaust air into a non-
functioning smoke or exhaust gas flue, obtain the
consent of the heating engineer responsible.
▯
If the exhaust air is conveyed through the outer wall,
a telescopic wall box should be used.
Circulating-air mode
The air which is drawn in is cleaned by the
grease filters and an activated carbon filter
and conveyed back into the kitchen.
Note: To bind odours in circulating-air mode, you must
install an activated carbon filter. The different options
for operating the appliance in circulating-air mode can
be found in the brochure. Alternatively, ask your dealer.
The required accessories are available from specialist
outlets, from customer service or from the Online Shop.
The accessory numbers can be found at the end of the
instructions for use.
