Electrical safety
•Regularly check the power cord for damage.
If the supply cord is damaged, it must be
replaced by the manufacturer, its service
agent or similarly qualified persons in order to
avoid a hazard.
•The appliance must be placed in such a way,
that the power supply is accessible at all
times.
•Before connecting the appliance to the power
supply, check that the power supply voltage
and current rating corresponds with the power
supply details shown on the appliance rating
label.
•Never use a damaged appliance! Disconnect
the appliance from the wall outlet and contact
your supplier if it is damaged.
•Danger of electric shock! Do not attempt to
repair the appliance yourself. In case of
malfunction, repairs are to be conducted by
qualified personnel only.
•To avoid damaging the cord, do not
squeeze, bend or chafe it on sharp edges.
Keep it away from hot surfaces and open
flames as well.
•Lay out the cord in such a way that no
unintentional pulling or tripping over it is
possible.
•Do not open the appliance casing under any
circumstances.
•Do not insert any foreign objects into the
inside of the casing.
•Never use accessories which are not
recommended by the manufacturer. They
could pose a safety risk to the user and
might damage the appliance. Only use
original parts and accessories.
•Keep the appliance away from any hot
surfaces and open flames. Always

Gas safety
•Always put lids on pots and pans when
cooking on a gas cooker.
Operation
Danger of fire!
oDo not flambé under the cooker
hood.
oDo not leave frying pans
unattended during use because
overheated fats or oils might catch
fire.
oNever leave naked flames under
the cooker hood.
oOnly fry underneath the cooker
hood when you are in the kitchen.
oDo not use the cooker hood
without the grease filters, or if
the filters are excessively greasy!
Caution! Accessible parts may
become hot when used with cooking
appliances.
Exhaust operation
Danger!
•During exhaust operation, the cooker hood
removes air from a room. If other fire
sources that require the surrounding air for
combustion are being operated in the
same room, (e.g. gas, oil or coal heaters),
the oxygen they require is taken away.
Thus flames could be suffocated and gas
could leak out or the fumes could be drawn
back into the room.
•In order to guarantee a safe operation,
there should be non- closable openings in
doors, windows or in an air intake wall box
to ensure a fresh supply of combustion
air. This will prevent the combustion fumes
from being drawn back into the room.
•When assessing the measures necessary,
always t ake the entire ventilation system
of the house into consideration. In case of
doubt, ask your local chimney sweeper for
help.
•Never secure the cooker hood to a
ventilation duct, or a room or exhaust gas
chimney! Do not let the air that is
removed from the room be drawn into a
duct where warm air is circulating. The
extracted air should only be drawn outdoors
through a separate ventilating duct that is
only for the extractor hood.
•When in extraction mode, air in the room is
being removed by the cooker hood. Please
make sure that proper ventilation measures
are being observed. The cooker hood
removes odours from room but not steam.
•There shall be adequate ventilation of the
room when the range hood is used at the
same time as appliances burning gas or
other fuels (not applicable to appliances
that only discharge the air back into the
room).
•The air must not be discharged into a flue
that is used for removing fumes from
appliances burning gas or other fuels (not
applicable to appliances that only discharge
the air back into the room).
Cleaning
•There is a fire risk if cleaning is not carried
out in accordance with the instructions.
•Pay attention to the sharp edges inside the
cooker hood, especially during cleaning.
•Always disc onnec t t he power supply
prior to cleaning the cooker hood. If the
switched fused connection unit is difficult
to reach, shut off the power supply by
using the corresponding circuit breaker at
the distribution board.
•Keep the cooker hood clean. Fat deposits
could catch on fire when exposed to high
temperatures.
3. INTENDED USE
•Your cooker hood can be operate d in
recirculated air operation or in exhaust
operation.

•Recirculated - air: Kitchen fumes are
removed and after purification are fed
back into the room through the upper air
outlet openings. The purification takes
place via the grease filters.

5. INSTALLATION
Important! We recommend that two people
carry out the installation. Pay attention to the
procedure described in the assembly
instructions.
Preparation
•Exhaust operation: The wall breakthrough
(core drill hole, min. 155mm) must be
carried out by a professional prior to
installing the extractor hood.
Pay attention to the length of the exhaust
hose when planning the wall breakthrough.
The exhaust hose must reach the outer
edge of the wall without any kinks.
Important! If the exhaust hose leads
through an outer wall, the air outlet on the
outside must be equipped with a cover
that has self-opening slits (not supplied).
This can be installed by the company that
performs the wall breakthrough.
If open fireplaces are operated in the same
room, ask your local chimney sweeper
about the local regulations prior to
installation.
If you are renting, then approval must be
obtained from the owner of the property.
•Attention! In order for the cooker hood to
reach optimal performance, mount it over
the middle of the cooking area.
•Plan the power connection prior to
installation so that a disturbing cable will
not be visible afterwards.
•The following accessories are required to
mount the cooker hood (not included with
the delivery):
→Exhaust duct
→Power drill
→Screwdriver
→Water level
→Cable detector
Electrical connection
•All fittings must be installed by a qualified
electrician in accordance with current IEE
Wiring Regulations (BS7671) and local
building regulations.
•Important! Always switch off the
electricity supply at the mains during
installation and maintenance. We
recommend that the fuse is withdrawn or
circuit breaker switched off a the
distribution board whilst work is in progress.
•Prior to drilling holes to secure it to the wall,
make sure that no cables or pipes will
become damaged (electric, gas, water,
etc.; test the areas in question with a cable
detector).
•This unit is double insulated and must not be
earthed. If there are any incoming earth
cables, they must be joined and well
insulated with good quality insulation tape.
This is to ensure earth continuity throughout
your property.
•Means for disconnection must be
incorporated in the fixed wiring in
accordance with the wiring rules. To
achieve this install appropriate switched
fused connection unit.
Note! A switched fused connection unit having
a contact separation of at least 3mm in all poles
should be connected in fixed wiring.
•Connect the incoming positive, neutral and
earth cables to the terminals of the
switched fused connection unit (fig.1 ).
Ensure connections are tight

Protective packaging
• The stainless steel surfaces of your new
cooker hood are covered with foil to
protect them from scratches during
transport and the corners of the glass
plates have protective caps on them.
Remove the protective foil and caps just
before permanently securing the cooker
hood.
• Also, remove styrofoam and protective
wrapping from the motor, inside the
appliance.
Measurement diagram
Installation with vent kit (not supplied)
• To use the exhaust operation, a wall
breakthrough is required with a diameter
of at least 155mm. We recommend that
you let a specialist (electrician) perform
the wall breakthrough (core drill hole).
• The shorter the vent kit is and the less
bends it has, the more efficient the
cooker hood will be.
• Official regulations may vary from region
to region. In case of doubt, we
recommend asking your local chimney
sweeper for advice.
• If you have an outlet to the outside, your
cooker hood can be connected by means
of an ex traction duct (enamel, aluminum,
f lexible pipe or inf lammable material
with an interior diameter of 150mm).
• The cooker hood should be placed at a
distance of 40~80cm above the cooking
place for best effect.

•Using bracket (3) as a templates, mark
and drill 6 holes in the wall (fig3). Inset
the wall plugs (8) (fig.3 ).
•Inset 2 long screws(7) to the middle two
holes ("*" mark dimension holes). Do not
fully insert the screws (7) ; let them
protrude out of the wall by about 4mm
(fig.3 )
•Hang the cooker hood (1) and fit the 2
upper holes to the 2 screws; Inset 2 long
screws (7) through the cooker hood into
the lower 2 holes & wall plugs (8); Screw
and tighten the cooker hood (1) onto the
wall.
•To fix the inner screws to the wall, the
central glass panel must be disassembled.
Follow the instructions below step by step.
(Fig. 4)
•Mount bracket (3) on the wall. Secure with
the remaining 2 sets of long screws (7)
and wall plugs (8)(fig. 7).
•Attach the vent kit. In the example on figure
8, an exhaust pipe of hardened PVC has
been used. Optionally, the airtight
connection of the vent kit can be improved
with duct tape (fig. 8).
Note: Sometimes, sponge tape covers
the holes. If the holes are located
behind the sponge tape, simply insert
the screw through the sponge tape.
Risk of injury: The chimney skirt may
have some sharp edges.
Note: Remember not to fix the screw
too tight, so that height adjustment
can be done easily later.
•Slide the upper chimney (2) into the lower
chimney (2). then pull the upper chimney
upwards (fig 9) . Adjust the height
of the chimney to approximatly the
required height. Fix the upper chimney
(2) on the bracket (3), and secure on both
sides with the 2 short screws (10) (fig.
10).
•Check tight fit of all parts.
Bridging larger distances
•Bridging larger distances to the outdoors
can be achieved by installing an external
motor inside the exhaust duct. To do this,
consult an electrician.
Installation without exhaust duct
•If you do not have an outlet to the outside,
the exhaust pipe is not required and the
installation is similar to the one shown in
the Installation with exhaust duct section.
