Prior to installation
For optimum extractor hood efficiency:
❑
Short, smooth air exhaust pipe.
❑
As few bends in the pipe as possible.
❑
Diameter of pipe to be as large as pos-
sible (ideal is l 120 mm ) 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.
The manufacturer of the
extractor hoods accepts no liability
for complaints which can be
attributed to the design and layout of
the pipework.
❑
Round pipes:
We recommend
Internal diameter at least. 120 mm.
❑
Flact ducts must have an internal
cross-section that equates to that of
round pipes with a 100/120 mm internal
diameter.
There should be no sharp bends.
l 100 mm approx. 078 cm
2
l 120 mm approx. 113 cm

If pipes have different diameters:
❑
Insert sealing strip.
❑
For exhaust-air mode, ensure that
there is an adequate supply of fresh air.
Exhaust outlet connection:
Pipe diameter: 100 or 120 mm.
❑
Insert the enclosed outlet connector and
twist it as far as it will go.
❑
If the pipe diameter is 120 mm, cut out
the inner part of the outlet connector.
Exhaust air flows upwards:
❑
Cut a hole in the top of the wall cupbo-
ard, including a groove for the mains
cable.

operating
instructions.
Exhaust flows straight out at the
back:
– inside the wall cupboard –.
❑
Cut a hole in the rear panel of the wall
cupboard, including a groove for the
mains cable.
Circulating-air mode
❑ With activated carbon filter if exhaust-air
mode is not possible.
Preparation:
❑
Cut a hole in the top of the wall cupbo-
ard, including a groove for the mains
cable.
