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

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 (at least
120 mm).

Flat ducts must have an internal cross-

section that equates to that of round
pipes.
There should be no sharp bends.
l 120 mm approx. 113 cm

l 150 mm approx. 177 cm

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.

Connecting a l 120 mm exhaust-air
pipe:

❑ Place the reducing connecting piece

onto the air connecting piece – Fig. 3 –
and fasten the exhaust pipe to it.

Circulating-air mode

Fig. 4

❑ With activated carbon filter if exhaust-air

mode is not possible.

If the extractor hood is suitable for

circulating-air mode, you can purchase the
complete installation set at specialist
outlets.

Preparing the ceiling

❑ The ceiling must be flat and horizontal.
❑ Ensure that the ceiling is capable of

providing a firm hold for mounting
screws and plugs. The enclosed plugs
are suitable for concrete and stonework.
If the ceiling is made of any other
material, use appropriate mounting
components.
