It is recommended that you connect the
appliance via a suitable socket . The
socket should be easily accessible after
the appliance has been installed.
If the socket is no longer accessible
after installation, an additional means of
disconnection must be provided for all
poles. Suitable means of disconnection
include switches with an all-pole
contact gap of at least 3 mm.
These include miniature circuit
breakers, fuses and contactors
(EN 60335).
The relevant connection data can be
found on the data plate (see "After
Sales/Warranty"). Ensure that this data
matches the voltage and frequency of
your household power supply.
Connection for air extraction
If the cooker hood is used at the
same time as a heating appliance
that relies on oxygen from the same
room, there is a risk in certain
circumstances of toxic fumes
building up.
It is essential that the "Warning and
Safety" instructions are observed.
The cooker hood should be installed
according to local and national
building regulations. Seek approval
from the building inspector where
necessary.
Use smooth pipes or flexible ducting
made from approved non-flammable
materials for exhaust ducting.
When using an external motor, make
sure that the exhaust ducting is
sufficiently rigid. The external motor
can cause an underpressure which
can result in the exhaust ducting
distorting.
To achieve the most efficient air
extraction with the lowest noise levels,
please note the following:
– The diameter of the exhaust ducting
should not be less than 150 mm.
– If flat ducting is being used, the cross
section must not be smaller than the
cross sectional area of the exhaust
connection.
– The exhaust ducting should be as
short and straight as possible.
– Only use wide radius bends.
– The exhaust ducting must not be
kinked or compressed.
– Ensure that all connections are
strong and airtight.
Remember that any constriction of
the air flow will reduce extraction
performance and increase operating
noise.
If the exhaust is ducted through an
outside wall, a telescopic wall vent or
a roof vent (available as an optional
accessory) is recommended.
