3.4 Electrical connection
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 you only find two wires in the main’s lead (blue and brown),
then neither must be connected to the earth terminal.
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: 205Watts
(motor 125Watts + 2 x 40Watt light bulbs)
3.5 Completing the installation
If you are setting the appliance to recirculation mode, then you
should now fit the two carbon filters. See the fitting of “Carbon
Filters” section on page 4.
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 3.4 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.
3.6 Extraction or circulation 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.
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.

3.7 Fitting the 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.
Fig. 10. Remove the grease filters.
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. The carbon filters should be replaced
every three months or if they show signs of damage.
4.0 Using the cooker hood
Important: this process must be followed before the cooker
hood is used for the first time.
■You should use a good quality stainless steel cleaner on
ALL of the stainless steel areas of your cooker hood,
before it is used for the first time.
■This will help to leave a silicone water-resistant film to
protect the stainless steel surfaces.
Fig. 13. How to use the cooker hood control panel:
■Find the control panel, which is located at the front
right of the canopy.
■There are several buttons on the control panel, which
perform separate functions.
■A = ON/OFF button
■B = Speed selection buttons
Low speed
Medium speed
High speed
■o C = Light on/off button
5.0 Cleaning your cooker hood
Important: before cleaning, always ensure that you have
switched your cooker hood off at the omni-polar switch,
set at the wall from the cable.
■Clean the external parts of your cooker hood with mild liquid
detergent and a new damp cloth.
■Never use abrasive powder, corrosive solvents or brushes.
■Never insert pointed objects into the motor’s protective grid.
■Only clean the control panel and grease filter grill with mild
liquid detergents and a new damp cloth.
■If you are using the appliance in recirculation mode,
then be sure to replace the carbon filter at the recommended
interval (see section opposite on “Fitting the carbon filter”). A
build up of grease could cause a fire hazard.
■Never attempt to clean the area above the grease filters.
6.0 Removing and cleaning the
grease filters
First 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.
■IMPORTANT: Let the grease filters dry thoroughly
before refitting them in the cooker hood.
7.0 Changing a light bulb
Important: before attempting to change a light bulb, you
must ensure that you have disconnected the cooker hood
from your mains supply.
■Remove the grease filters.
■Prior to touching the light bulbs ensure they are cool.
■Find the bulb that requires replacement in the light fixture
which is inside the exposed section of the canopy.
■Unscrew the light bulb that needs to be replaced and insert a
new E14 40W (max) bulb.
■Defective bulbs should be replaced immediately.
■If the lights still do not work, make sure that the lamps are
fitted properly into their housings before you call for technical
assistance.
■Refit the grease filters.
