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 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.

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: 150 mm.
•
Flat ducts must have an internal cross-section
that equates to that of round pipes.
There should be no sharp bends.

•
If pipes have different diameters: Insert
sealing strip.
•
For exhaust-air mode, ensure that there is an
adequate supply of fresh air.
Connecting a
l
150 mm exhaust-air pipe:
•
Mount the pipe directly
onto the air outlet on the
hood.
