some preliminary remarks
An extractor hood should be installed in accordance with
national and local regulations. The minimum distance
between the underside of the extractor hood and the hob
should be 65 cm.
The appliance should be connected by a registered fitter.
Damage arising from incorrect connection or incorrect
fitting is not covered by the guarantee.
NB:
If an extractor hood and a heat source (for example, gas-,
oil- or coal-fired cookers) which take air from the same
room are in use at the same time, there is a possibility that
the extractor hood will cause an underpressure in that room.
The maximum permitted underpressure is 4 Pa, so that no
combustion gases from the heat source can find their way
back into the room. For this reason, an air supply is required
- to provide a constant supply of fresh air to the room.
electrical connection
The extractor hood's plug should be accessible after fitting
or the extractor hood should be isolated by a bipolar switch
with 3 mm plug pins.
When making the electrical connections, make sure that the
socket is earthed and that the voltage and frequency
correspond to the values given on the data plate.
If the connection cable is damaged, it should be replaced by
the service department of the manufacturer or similarly
qualified persons in order to prevent dangerous situations
from arising.

discharge
The discharge should not be connected to a duct which is
also used for other purposes under any circumstances.
Bear in mind any local regulations concerning the ventilation
of gas appliances.
The discharge may pass straight through the wall to the
outside, provided that the wall opening is protected - by
means of a grating - against rain, leaves, and the like getting
in. The passage of the discharge may not be restricted by
the wall grating by more than 20%.
We advise the use of as large a discharge duct as possible.
A duct with a smaller diameter will have a low extraction
capacity and produce higher noise levels.
Bends produce resistance. Make sure that the duct has a
smooth run and has as few bends as possible. Draw the
flexible pipe out as far as possible.
Before starting to drill, check that there are no installed
pipes present.
The discharge stump has a diameter of 150 mm. It is best if
the discharge pipe also has this diameter.
A reducing piece (150 mm to 120 mm) is supplied with the
appliance for connection to a 120 mm discharge pipe.
