the discharge
The discharge may under no circumstances be connected to
a duct that is also used for other purposes. Bear in mind the
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 against
the entry of rain, leaves and the like by a grating. The
passage of the discharge may not be restricted by more than
20% by the wall grating.
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 installation pipes (for gas, water, etc.)
present.
The discharge stump has a diameter of 125 mm. It is best if
the discharge pipe also has this diameter.
electrical connection
The plug should be accessible after the extractor hood is
fitted or it should be possible to disconnect the extractor
hood from the mains by means of a bipolar switch with a
contact gap of 3 mm.
When making the electrical connections, take care that the
voltage and frequency correspond to the values given on the
data plate.
If the connection cable becomes damaged, it should be
replaced by the manufacturer’s service department or by a
person with equivalent qualifications, in order to prevent
dangerous situations from arising.
safety
Attention: Make sure that there is a sufficient supply of
fresh air, if an extractor hood and a heat source (e.g. gas
cooker) that both consume air from the same room, are
switched on at the same time. The maximum permitted
underpressure is 4 Pa.
