Before installation
With exhaust mode, a backwash valve
should be installed unless it is already in-
corporated in the exhaust pipe or wall box.
If a backwash valve is not included with
your appliance, your dealer can supply you
with one (see accessories).
Installation backwash valve:
Insert the backwash valve in the mounting
openings on the air connector.
If the exhaust air is being routed
through the outside wall
, a telescopic
wall box should be used.
Connecting to Ø100 mm exhaustair duct
Attach the reducing adapter (enclosed or
available from specialist dealer) to the air
outlet. Attach the exhaust-air duct to the
adapter.
Connecting to Ø120 mm exhaustair duct
Attach the exhaust-air duct directly to the
air outlet.
Connecting to Ø150 mm exhaustair duct
Attach the enlarging adapter (enclosed or
available from specialist dealer) to the air
outlet. Attach the exhaust-air duct to the
adapter.
If a backflow flap has been installed, check
that it functions properly.
Circulating-air mode
With activated carbon filter if exhaust-air
mode is not possible.
The air purified by an additional
activated carbon filter is returned to the
room.
After installing the extractor hood, insert
the activated carbon filter.
For installing see Filters and maintenance.
If the extractor hood is installed beneath a
cabinet, ensure that there is an adequate
air outlet (min. 177 cm
2
).
ṇ The extractor comes as standard
equipped with a protective grid in the air
connector. If this is has been removed (in
the case of exhaust air operation), the air
connector must be supplemented by a
reducer piece with protective grid (see
section on special accessories).
