Warning and Safety instructions

This appliance co n forms to cur rent
safety requirements. Inappropriate
use could, however lead to risk of
accidents to the user and damage
to the appliance.

Before using this appliance for the
first time read the operating instruc­tions carefully. They contain import­ant information on safety, use and
maintenance of the appliance. Th is
way you will avoid the risk of acci­dents and damage to the appliance.

Keep these operating instructions in
a safe place and ensure that new
users are familiar with the content.
Pass them on to any future owner.

Appropriate use

The appliance is intended for do-

mestic use only.
The manufacturer cannot be held re­sponsible for any damage caused by
improper use or by non-observance of
these instructions.

T echnical safety

Before connecting the cooker

hood to the mains supply make
sure that the voltage and frequency de­tails given on the data plate corre­spond with the on-site electricity sup­ply, otherwise the appliance could be
damaged. If in doubt consult a quali­fied electrician.

The electrical safety of this ap-

pliance can only be guaranteed
when continuity is complete between
the appliance and an effective earthing
system which complies with local and
national regulations. It is most import­ant that this basic safety requirem e nt is
tested by a qualified electrician.
The manufacturer cannot be held re­sponsible for the consequences of an
inadequate earthing system. (e.g. elec­tric shock).

Installation work and repairs may

only be carried out by suitably
qualified and competent persons to en­sure safety. Repairs and other work by
unqualified persons could be dan­gerous and the manufacturer will not
be held responsible.

Warning and Safety instructions

4

The appliance is only completely
isolated from the mains supply

when:

– it is switched of f at the fu se d spu r

connection, or

– it is switched of f at the wal l soc ke t

and the plug has been withdrawn
(do not pull on the cable, only on the

plug), or
– the mains fuse is withdrawn.
Ensure current is not supplied to the ap-

pliance while maintenance or repair
work is being carried out.

Do not connect the appliance to

the mains electricity supply by an
extension lead. Extension leads do not
guarantee the required safety of the ap­pliance.(e.g. danger of overhe ating).

Use of the appliance

Do not let small children play with

the appliance or its controls. Super­vise its use by the elderly or infirm.

When fitted above an open grill the

cooker hood must not be used in
recirculation mode.

Never use an open flame beneath

the cooker hood. To avoid the
danger of fire do not flambé or grill over
an open flame. When switched on the
cooker hood could draw flames into the
filters. Fat particles drawn into the
cooker hood present a fire hazard.

When using the cooker hood over

a gas hob ensure that any burners
in use are always covered by a pan.
Otherwise flames could be drawn up

by the suction of the cooker hood,
parts of which could then be damaged.

Always switch the cooker hood on

when a cooking zone is in use,
otherwise conden sa ti o n ma y collect in
the hood, which could ca us e corrosion.

When cooking with oil or fat, chip

pans and deep fat fry ers etc, do
not leave the pans unattended. Never
leave an open grill unattended when
grilling. Overheated oil and fat can ig­nite and could set the cooker hood on
fire.

Do not use the cooker hood with-

out the grease filter in place.
This way you will avoid the risk of
grease and dirt getting into the ap­pliance and hindering its smooth oper­ation.

Clean or change the filter regularly.

An over-greasy filter is a fire ha­zard.

Under no circumstances use a

steam cleaner to clean this ap­pliance. Pressurised steam could reach
the electrical components and cause a
short circuit.

Warning and Safety instructions

Installation

The distance between the top of
the cooker/hob and the bottom of

the cooker hood must measure at least:
– 45 cm above electric cookers/hobs

– 65 cm above gas cookers/hobs.
– 65 cm above an open grill.

For other manufacturer’s cooking ap­pliances maintain the safety distance
as recommended in their Installation
and Operating instructions.

If more than one appliance is fitted be­neath the cooker hood and they have
different minimum safety distances to
the cooker hood, select the higher dis­tance.

Safety regulations prohibit the fit­ting of a cooker hood over solid

fuel stoves.

All ducting, pipework and fittings

must be of non-flammable ma­terial. These can be obtained f rom the
Spare Parts department or from buil­ders’ merchants.

The appliance must not be con-

nected to a chimney or vent flue
which is in use. Neither should it be
connected to ducting which ventilates
rooms with fireplaces.

If exhaust air is to be extracted into

a chimney or ventilation duct no
longer used for other purposes, take
professional advice.

When using the cooker hood at the

same time as another heating ap­pliance which depends on the air in the
room, (e.g. gas, oil or coal fired

heaters, continuous flow or other water
heaters, gas cooker, gas hob or gas
oven) special care must be taken, as
the action of the cooker hood extracts
air from the room, which these types of
heater need for comb u sti o n .

In order to ensure safe operation, and
to prevent the gases given off by the
heating appliances from being drawn
back into the room when the extractor
and the heater are in operation simulta­neously, an underpressure in the room
of 0.04 mbar (4 pa) is the maximu m
permissible.

Ventilation can be maintained by air in­lets which cannot be blocked, in win­dows, doors and outside wall vents, or
by other technical measures, such as
ensuring that the extractor can only be
switched on when the heating ap­pliance is switched off or vice-versa.

N.B.: The overall ventilation condition of
the dwelling must be taken into ac­count.

If in any doubt, the advice of a compe­tent builder or, for gas, a “Corgi” instal­ler must be sought.

If the cooker hood is used in recircula­tion mode (with the recirculation Micro­Fil te r ) , there are no restrictions.

Warning and Safety instructions

6

In countries where there are areas

which may be subject to infest a­tion by cockroaches or other vermin,
pay particular attention to keeping the
appliance and its surroundings in a
clean condition at all times. Any dam­age which might be caused by cock­roaches or other vermin will not be
covered by the appliance guarantee.

Appliances with external fans

For appliances with an external fan
motor fitted (EX models) the conn ection
of the two units must be made using
the connection cable and the plug co n­nectors. Make sure the correct combi­nation of the two appliances has been
selected.

Separate fitting instructions are sup­plied with the external fan.

Disposal of your old appliance

Before discarding an old ap-

pliance switch off and disconnect
it from the power supply. Cut off and
render any plug useless. Cut off the
cable directly behind the appliance to
prevent misuse. This should be done
by a competent person.

The manufacturer cannot be held re­sponsible for any damage caused
by non-observance of thes e in str u c ­tions.

Description of the funct ions

The cooker hood works

. . . by air extraction:

The air is drawn in, cleaned by th e
grease filters and directed outside.

The cooker hood is fitted with a
non-return flap, (see "Installation").
This flap is closed when the cooker
hood is switched off. No exchange of
room air and outside air can take
place. When the cooker hood is
switched on the non-return flap opens
for the cooking smells to be blown di­rectly outside.

. . . by air recirculaton:

The air is drawn in and cleaned first by
the grease filters. In addition it is then
cleaned by the Recirculation Micro-
Filters. The cleaned air is then recircu­lated back into the kitchen through a
vent in the top of the cooker hood.

Before using the cooker hood for
the first time in recirculation mode,
ensure that the recirculation micro­filters are in place. See Section on
"Cleaning and care".

. . . with an external fan

The EX models are designed to be con­nected to an external fan located out­side the room.

The external fan is connected to the
cooker hood by a control cable and is
operated by the control panel on the
cooker hood.
