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.
IMPORTANT:
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:
6”
.
❑
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.
Prior to installation
Connecting a
l
6” exhaust-air pipe:
❑
Mount the pipe
directly onto the
air outlet on the
hood.
