Before installation
Optimum performance of the extractor
hood:
❑ Short, smooth exhaust-air pipe.
❑ Minimum number of pipe bends.
❑ Largest possible pipe diameter
(120 mm dia. recommended) and large
pipe bends.
If long, rough exhaust-air pipes,
many pipe bends or smaller pipe
diameters are used, the air extraction
rate will no longer be at an optimum
level and there will be an increase in
noise.
ṇThe manufacturer of the
extractor hoods accepts no liability
for complaints which can be
attributed to the design and layout of
the pipework.
❑ Round pipes:
Short discharge pipe:
Inner diameter at least 100 mm,
extended discharge pipe:
Inner diameter at least 120 mm.
❑ Flat ducts must have an inner cross-
section equivalent to round pipes with
an inner diameter of 100/120 mm.
There should be no sharp bends.
100 m dia approx. 178 cm

125 m dia approx. 113 cm

❑ If pipe diameters differ:
Insert sealing strip.
❑ Ensure an adequate air supply for
exhaust-air mode.
If the exhaust air is conveyed through
the exterior wall, a telescopic wall box
should be used.
Exhaust air upwards:
Pipe diameter: 100 or 120 mm
❑ Break off cover on the top of the
extractor hood; strike the retaining points
with a tool.
ṇTo prevent damage to the fan, hold the
tool vertically.
❑ Remove the broken off metal part
(possibly a noisy and disruptive
procedure).
❑ If the pipe diameter is 120 mm, cut out
the inner part of the exhaust-air
connection.
❑ Insert the exhaust-air connection and
turn as far as possible.
ṇTo prevent damage to the fan, hold the
tool vertically.
❑ Remove the broken off metal part
(possibly a noisy and disruptive
procedure).
❑ If the extractor hood has 2 motors, the
opening on the plastic part must be
made at the rear; cut through the 3 ribs
and remove the cut-off part.
Exhaust air towards the rear:
Pipe diameter: 100 mm
❑ Break off cover on the rear panel of the
extractor hood; strike the retaining
points with a tool.
❑ Cut off the outer part of the exhaust-air
connection.
❑ Insert the inner part and turn as far as
possible.
Circulating-air mode
❑ With activated carbon filter if exhaust-air
mode is not possible.
❑ The air purified by an additional
activated carbon filter is conveyed back
into the room.
❑ For insertion of the activated carbon
filter see Instructions for use.
❑ If the extractor hood is switched from
exhaust-air mode to circulating-air
mode, the exhaust-air opening must be
sealed to prevent a hazardous situation
(see optional accessories in the
Instructions for use).
Electrical connection
WARNING: THIS APPLIANCE MUST BE
EARTHED
IMPORTANT: Fitting a Different Plug:
The wires in the power cord are colour-
coded as follows:
Green and Yellow – Earth
Blue – Neutral
Brown – Live
If you fit your own plug, the colours of these
wires may not correspond with the identify-
ing marks on the plug terminals.
Proceed as follows:
1. Connect the green and yellow (Earth)
wire to the terminal in the plug marked
‘E’ or with the symbol ( ), or
coloured green or green and yellow.
2. Connect the blue (Neutral) wire to the
terminal in the plug marked ‘N’ or
coloured black.
3. Connect the brown (Live) wire to the
terminal marked ‘L’, or coloured red.
