Optimum performance of the extractor
hood:
❑
Short, smooth extraction pipe.
❑
As few pipe bends as possible.
❑
Largest possible pipe diameter (prefera-
bly 150 mm ø) and large pipe bends.
❑
Round pipes:
We recommend
for single-motor model,
inner diameter of at least 120 mm
for double-motor model.
inner diameter of at least 150 mm
❑
Flat ducts must have an inner cross-
section equivalent to round pipes
which have an inner diameter of
120/150 mm.

❑
If pipe diameters differ:
use sealing
strip.
❑
Ensure an adequate air supply
for
exhaust-air mode.

Extractor hoods with 120 mm Ø air
outlet:
100 mm Ø extraction pipe

Insert the reducing connector (see optio-
nal accessories on the last page) into the
air-pipe connector and then attach the
exhaust-air pipe.

Attach the exhaust-air pipe directly to
the air-pipe connector.

Extractor hoods with rectangular air
outlet:
❑
Screw the enclosed
air-pipe connector
over the air outlet.
Recirculated
air mode
❑
The air cleaned by an additional activa-
ted carbon filter is conveyed back into
the room.
❑
In recirculated air mode the exhaust ope-
ning must be protected by a grille (see
optional accessories on the last page) in
order to prevent a mechanical or electri-
cal hazard.
