Prior to installation
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.
120 mm l approx. 113 cm
150 mm l approx. 177 cm
If pipe diameters differ: use sealing
strip.
Ensure an adequate air supply for
exhaust-air mode.

Recirculated
air mode
Screw the reducing connector (see
optional accessories on the last page)
onto the air outlet.
Attach the extraction pipe to the redu-
cing connector.
Attach the exhaust-air pipe directly to
the air outlet..
If a one-way flap has been fitted, con-
Screw the enclosed
air-pipe connector
over the air outlet.
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.
