2.0 Dimensions
If the unit is installed for use above a gas appliance then the provision
for ventilation must be in accordance with the Gas Safety Codes of
Practice BS.6172, BS.5440 & BS.6891
(Natural Gas) and BS.5482 (LP Gas) 1994, the Gas Safety (Installation

Do not alter or modify the specifications of this product in any way.
3.1 General Installation
When installed between adjoining wall cabinets, the cabinets must not
overhang the hob.
The edges of the cooker hood are sharp - so handle the unit with care,
especially during installation and cleaning.
If the room where the cooker hood is to be used contains a fuel burning
appliance such as a central heating boiler then its flue must be of the
sealed or balanced flue type. If other types of flue or appliances are
fitted, ensure that there is an adequate supply of air in the room.
To ensure high extraction efficiency of the hood, ensure that the
ducting is fire retardant and bends are no more than 90 degrees. Also
ensure the ducting for the extractor function has the same diameter as
the outlet hole all the way through.
The cooker hood should not be exposed to a direct heat source from
the cooking device under it i.e. a naked flame from a gas burner or heat
from electric hobs without a pan on them.
Lights on the appliance should only be left on when using the unit.

indicated on the rating plate are exactly the same as the
voltage and frequency of the home. The rating plate is on
inside of the hood behind the grease filters. Connect the unit
to the mains supply after the rest of the installation process
has been completed.

3.5 Wiring
This cooker hood is intended for fitted and permanent installation.
The cooker hood’s power cable must be fitted upstream from the
electrical connection, using an omni-polar switch with a contact
distance of at least 3 mm. The fuse must be rated at 3 amps.
We recommend that the appliance is connected by a qualified
electrician, who is a member of the N.I.C.E.I.C and who will comply with
the I.E.E and local regulations. The wires in the mains lead are coloured
in accordance with the following UK code:
Blue = Neutral
Brown = Live
Green/Yellow = Ground
If only two wires are found in the mains lead (blue and brown), then the
earth terminal must NOT be connected.
As the colours of the wires in the appliance’s mains lead may not
correspond with the coloured markings identifying the terminals in your
spur box, please proceed as follows:
The blue wire must be connected to the terminal marked “N” (neutral),
or coloured black. The brown wire must be connected to the terminal
marked “L” (live), or coloured red.
Power Consumption: 205W (motor 125W + 2x 40W light bulbs)
IMPORTANT
THIS APPLIANCE MUST BE EARTHED
It should only be connected by a qualified electrician, using
fixed wiring via a double pole switched fused spur outlet (UK
ONLY).
3.7 Extraction or Recirculation Mode?
To get optimum performance from your cooker, the air will be taken
out of the room via external ducting.
Unfortunately if you live in a flat or the hood is too far from an outside
wall, this may not be possible. The only alternative is to recirculate the
air.
In recirculation mode stale air is taken via the grease filter, and passed
through a charcoal filter for purification. The air then re-enters the
kitchen via an opening in the hood.
3.7.1 What is a Carbon Filter and do I need one?
All cooker hoods have a grease filter but if you are using your cooker
hood in recirculation mode, then a carbon filter must be fitted in
addition to the grease filter.
•Now remove both
chimney sections D and C
and fix a second bracket
between the two pencil
marks that were made
either side of chimney
section C.
•Refit chimney section
C to the hood using the
screws provided. Secure
the bottom of chimney
section C to the fixing
bracket (screws provided).
•Slide chimney section D
inside of section C. Lift
chimney section D up to
the ceiling and secure it
to the top fixing bracket
using (screws provided).
3.6 Installation Completion
If you are setting the appliance to recirculation mode, then you should
now fit the two carbon filters (see Section 3.8).
The electrical connection must correspond to the electrical requirement
noted on the rating plate, which is placed inside the cooker hood. The
appliance should now be connected to the electrical supply. See above
for detailed information on the electrical connection.
Refit the grease filter and then switch on the mains supply to the
appliance. Check that the appliance is operating correctly by selecting
each speed and switching the light bulbs on and off.
3.8 Carbon Filter
If the appliance is being used to be used in recirculation mode then
it is necessary to fit carbon filters. This will help to absorb unpleasant
odours caused by cooking.
IMPORTANT
Before attempting to fit or remove the carbon
filters, you must ensure that you have disconnected the
cooker hood from your mains supply.

Clean the external parts of your cooker hood with lukewarm mild liquid
detergent and a new damp cloth. Never use metal pads, chemical,
abrasive material or a stiff brush. Never insert pointed objects into the
motor’s protective grid.
5.2 Carbon Filters (Recirculation Mode)
If the appliance is being used in recirculation mode then it is necessary
to replace the carbon filters at least once a year for general cooking
applications. Heavier use of the cooker hood will require higher
frequency carbon filter replacement. Telephone [phone]

Speed 1: Used for light cooking (small amount of steam).
Speed 2: Used for general cooking.
Speed 3: Used for heavy cooking (large amount of steam).
5.3.1 Quick Timer
Press & hold the - and + buttons for 1 second. The digital display will
begin flashing. After five minutes the motor & light will automatically
turn off and a buzzer will sound for one second.
5.3.2 Booster Function
The cooker hood has a booster function, to activate the booster,
increase the speed to setting 4. The hood will increase speed for 5
minutes, before slowing down again.
Figure 13. Removing metal grease filters
•Remove the grease filters.
•Hook the carbon filter over the pins that are located at the end of
the motor (Figure 9). Turn the carbon filter clockwise, until you feel
it click into place.
•Repeat this process for the second carbon filter. You need to place
a carbon filter at either end of the motor.
•Refit the grease filters.
4.0 Operation
5.3 Grease Filters
Grease filters collect grease and dust which has a direct effect on the
efficiency of the cooker hood. If not cleaned, the (potential flammable)
grease residue will saturate on the filter. Clean the filter every month
to prevent any risk of fire.
Remove the grease filters by pulling down on the handle and pulling
them away from the cooker hood. Soak the grease filter in hot water
and washing up liquid for about an hour. Rinse them off thoroughly
with hot water. Repeat the process if required. Refit the grease filters
once they have dried.
It is important to let the grease filters dry thoroughly before refitting
them in the cooker hood.
5.4 Lights
Prior to touching the light bulbs ensure they are cool. Find the bulb
that requires replacement, you will find it located in the light fixture
which is inside the exposed section of the canopy.
Disconnect the light wiring point and remove the bulb holders and
wiring from the hood. Important: It is not possible to replace the bulbs
individually, it will be necessary to obtain the bulbs, bulb holders and
wiring as a complete part (LED light: MAX 1.5W).
Fit the replacement bulbs, bulb holders and wiring in the same manner
as the originals and reconnect the light wiring point.
