Before installation
Optimum efficiency of the extractor
hood:
❑ Short, smooth exhaust pipe.
❑ As few bends as possible.
❑ Pipe diameter as large as possible
(ideally 150 mm dia.) and wide pipe
bends.
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.
ṇ
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
Short exhaust air pipe:
inside diameter min. 120 mm,
Longer exhaust air pipe:
inside diameter min. 150 mm.
❑ Flat ducts must have an inside
cross-section equivalent to that of the
round pipes.
There should be no sharp bends.
l 120 mm dia. approx. 113 cm

l 150 mm dia. approx. 177 cm 2
❑ If pipe diameters differ, insert sealing
strip.
❑ Ensure that there is an adequate air
supply for exhaust air mode.
Exhaust air directed backwards:
Only possible inside tall wall cupboards
depending on the size of the exhaust air
pipe.
❑ Make a hole in the rear panel of the wall
cupboard, cutting out a notch for the
power supply cable.
Exhaust air directed upwards:

2. If fitted, cut out the cupboard base to a
min. depth of 270 mm over the entire
width.
Connecting a 150 mm exhaust pipe:
❑ Attach the exhaust pipe directly to the air
connector.
Connection of 120 mm l exhaust air
pipe:
❑ Attach enclosed reducing connector to
the air outlet.
Holes in the air outlet must be sealed.
❑ Attach exhaust air pipe to the reducing
connector.
Circulating-air mode
❑ With activated carbon filter if exhaust-air
mode is not possible.
