Safety warnings
for the installer
When used as an extractor unit, the hood must
be fitted with a 150mm diameter hose.
Should there already be a pipe of diameter 125
mm that ducts to the outside through the walls
or roof, it is possible to use the 150/125 mm
reduction flange provided. In this case the hood
will be slightly more noisy.
When installing the hood, make sure you
respect the following minimum distance
from the top edge of the cooking hob/ring
surfaces:
electric cookers
500 mm
gas cookers
650 mm
coal and oil cookers
700 mm min.
The national standard on fuel-burning systems
specifies a maximum depression of 0.04 bar in
such rooms.
The air outlet must not be connected to chimney
flues or combustion gas ducts. The air outlet
must under no circumstances be connected to
ventilation ducts for rooms in which fuel-burning
appliances are installed.
It is advisable to apply for authorization from the
relevant controlling authority when connecting
the outlet to an unused chimney flue or
combustion gas duct.
The air outlet installation must comply with the
regulations laid down by the relevant authorities.
When the unit is used in its extractor version, a
sufficiently large ventilation hole must be
provided, with dimensions that are
approximately the same as the outlet hole.
National and regional building regulations
impose a number of restrictions on using hoods
and fuel-burning appliances connected to a
chimney, such as coal or oil room-heaters and
gas fires, in the same room.
Hoods can only be used safely with appliances
connected to a chimney if the room and/or flat
(air/environment combination) is ventilated from
outside using a suitable ventilation hole approxi-
mately 500-600 cm
2
large to avoid the
possibility of a depression being created during
operation of the hood.
If you have any doubts, contact the relevant
controlling authority or building inspectors
office.
Since the rule for rooms with fuel burning
appliances is outlet hole of the same size as the
ventilation hole, a hole of 500-600 cm
2
, which
is to say a larger hole, could reduce the perfor-
mance of the extractor hood.
If the hood is used in its filtering function, it will
operate simply and safely in the above
conditions without the need for any of the
aforementioned measures.
When the hood is used in its extractor function,
the following rules must be followed to obtain
optimal operation:
short and straight outlet hose
keep bends in outlet hose to a minimum
never install the hoses with an acute angle,
they must always follow a gentle curve only
keep the hose as large as possible
(preferably the same diameter as the outlet
hole).
Failure to observe these basic instructions will
drastically reduce the performance and increase
the noise levels of the extractor hood.
for the user
Always cover lighted elements, to prevent
excess heat from damaging the appliance. In
the case of oil, gas and coal fired cookers it is
essential to avoid open flames.
Also, when frying, keep the deep frying pan on
the cooker top/cooker under careful control.
The hot oil in the frying pan might ignite due to
overheating.
The risk of self-ignition increases when the oil
being used is dirty.
It is extremely important to note that
overheating can cause a fire.
Never carry out any flambé cooking under
the hood.
Always disconnect the unit from the power
supply before carrying out any work on the
hood, including replacing the light bulb
(take the cartridge fuse out of the fuse holder or
switch off the automatic circuit breaker).
It is very important to clean the hood and
replace the filter at the recommended
intervals. Failure to do so could cause
grease deposits to build up, resulting in a
fire hazard.
