Prior to installation
For optimum extractor hood efficiency:
Short, smooth air exh
aust pipe.
As few bends i
n the pipes as possible
Diamet
er of pipe to be as large as
possible and no tight bends in pipe.
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.

Round pipes:
we recommend internal diameter: 150
mm.
Flat duct must have an internal cross
section that equates to that of round
pipes.
There should be no sharp bends.
Ø 150 mm ca. 177cm

If pipes have different diameters:
insert sealing strip.
For exhaust-air mode, ensure that
there is an adequate supply of fresh
air.
Connecting a Ø 150 mm exhaust air
pipe:
Mount the pipe directly onto the air
outlet on the hood. Duct smaller than
150 mm are not reliable.
W
ith higher distance from the cooking
hob, the air delivery performances are
reduced. During the design and
layout of the mounting of the cooker
hood, kindly consider also the funnel-
shape of the vapour rising with
inclination of ca 10 – 15°.
Preparing the celing:
T
he ceiling must be flat and
horizontal.
Ensure that the ceiling is capable of
providing a firm hold for mounting screws
and plugs.
T
he enclosed plugs are suitable for
concrete and stonework. If the ceiling is
made of any other material, use
appropriate mounting components.
Attention: The cooker hood is
equipped with standard fixing material.
The person who is mounting the hood
should make sure that fixing elements are
suitable for the ceiling that is found. The
manufacturer declines any responsibility
for damages caused by a wrong mounting
oder use of unsuitable fixing elements for
the ceiling found.
For the weight kindly look at the M
F
igures. We reserve the right to
construction changes within the context of
technical development.
