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

(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.

❑

If pipes have different diameters:

Insert sealing strip.

❑

For exhaust-air mode, 

ensure that

there is an adequate supply of fresh air.

Circulating-air mode

❑

With activated carbon filter if exhaust-air
mode is not possible.

The complete

installation set can be
obtained 

from 

specialist

outlets.

instructions.

Prior to installation

Connecting a 

l

150 mm exhaust-air

pipe:

❑

Mount the pipe 
directly onto the 
air outlet on the 
hood.
If using an 
aluminium pipe, 
smooth the 
connection area 
beforehand.

Connecting a 

l

120 mm exhaust-air

pipe:

❑

Attach the 
reducing 
connector directly 
to the air pipe.

❑

Attach the 
exhaust-air pipe 
to the reducing 
connector.
