Warning and Safety instructions
This appliance conforms to current
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 instruc-
tions carefully. They contain import-
ant information on safety, use and
maintenance of the appliance. This
way you will avoid the risk of acci-
dents 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 re-
sponsible for any damage caused by
improper use or by non-observance of
these instructions.
echnical safety
Before connecting the cooker
hood to the mains supply make
sure that the voltage and frequency de-
tails given on the data plate corre-
spond with the on-site electricity sup-
ply, otherwise the appliance could be
damaged. If in doubt consult a quali-
fied 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 import-
ant that this basic safety requirement is
tested by a qualified electrician.
The manufacturer cannot be held re-
sponsible for the consequences of an
inadequate earthing system. (e.g. elec-
tric shock).
Installation work and repairs may
only be carried out by suitably
qualified and competent persons to en-
sure safety. Repairs and other work by
unqualified persons could be dan-
gerous 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 off at the fused spur
connection, or
– it is switched off at the wall socket
and the plug has been withdrawn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– the mains fuse is withdrawn.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 ap-
pliance.(e.g. danger of overheating).
Use of the appliance
Do not let small children play with
the appliance or its controls. Super-
vise 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 condensation may collect in
the hood, which could cause corrosion.
When cooking with oil or fat, chip
pans and deep fat fryers etc, do
not leave the pans unattended. Never
leave an open grill unattended when
grilling. Overheated oil and fat can ig-
nite 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 ap-
pliance and hindering its smooth oper-
ation.
Clean or change the filter regularly.
An over-greasy filter is a fire ha-
zard.
Under no circumstances use a
steam cleaner to clean this ap-
pliance. Pressurised steam could reach
the electrical components and cause a
short circuit.
Warning and Safety instructions
5

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 ap-
pliances maintain the safety distance
as recommended in their Installation
and Operating instructions.
If more than one appliance is fitted be-
neath the cooker hood and they have
different minimum safety distances to
the cooker hood, select the higher dis-
tance.
Safety regulations prohibit the fit-
ting of a cooker hood over solid
fuel stoves.
All ducting, pipework and fittings
must be of non-flammable ma-
terial. These can be obtained from the
Spare Parts department or from buil-
ders’ 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 ap-
pliance 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 combustion.
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 simulta-
neously, an underpressure in the room
of 0.04 mbar (4 pa) is the maximum
permissible.
Ventilation can be maintained by air in-
lets which cannot be blocked, in win-
dows, doors and outside wall vents, or
by other technical measures, such as
ensuring that the extractor can only be
switched on when the heating ap-
pliance is switched off or vice-versa.
N.B.: The overall ventilation condition of
the dwelling must be taken into ac-
count.
If in any doubt, the advice of a compe-
tent builder or, for gas, a “Corgi” instal-
ler must be sought.
If the cooker hood is used in recircula-
tion mode (with the recirculation Micro-
Filter) , there are no restrictions.
Warning and Safety instructions

In countries where there are areas
which may be subject to infesta-
tion by cockroaches or other vermin,
pay particular attention to keeping the
appliance and its surroundings in a
clean condition at all times. Any dam-
age which might be caused by cock-
roaches 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 connection
of the two units must be made using
the connection cable and the plug con-
nectors. Make sure the correct combi-
nation of the two appliances has been
selected.
Separate fitting instructions are sup-
plied 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 re-
sponsible for any damage caused
by non-observance of these instruc-
tions.

Description of the functions
The cooker hood works
. . . by air extraction:
The air is drawn in, cleaned by the
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 di-
rectly 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 recircu-
lated 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 micro-
filters are in place. See Section on
"Cleaning and care".
. . . with an external fan
The EX models are designed to be con-
nected to an external fan located out-
side 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.
Description of the functions

Operation
Main switch
When the main switch is set to “I” the
cooker hood is ready for operation.
When the cooker hood is switched off
using the main switch, it will retain the
most recent setting when next switched
on.
Switching on
– Press the On/Off touch control.
The indicator lamp for this touch control
lights up and at the same time the
motor switches on. The motor runs at
power level “lI”.
Selecting the power level
Depending on how much the air needs
to be filtered, there are four power le-
vels available. For normal cooking a
low to medium level is usually suffi-
cient. For frying or cooking food with a
strong aroma the highest level marked
IS (Intensive Setting) is recommended.
– Use the –/+controls to select the
power level required.
Touch control + = higher setting
Touch control –= lower setting
The indicator lamps show which power
level has been chosen.
Operation
11

Run-on option
If the air still needs to be cleared after
cooking, the cooker hood can be set to
continue running.
The fan motor will then switch off auto-
matically after a further 5 or 15 minutes.
– Press the run-on option touch control.
Press once = 5 minutes run-on time
Press twice = 15 minutes run-on time
Press three times = fan is switched off
The relevant indicator lamp glows to
confirm the time selected.
If no run-on time is selected neither
lamp lights up.
To deactivate the run-on option time,
press the run-on option touch control
until both indicator lamps go out.
Switching off
– Use the On/Off touch control to
switch the fan off.
If the cooker hood is not to be used for
a longer period of time (e.g. overnight
or during holidays), switch it off using
the main switch.
Switching the lighting on or off

be switched on or off independently of
the fan.
– Press the lighting touch control.
– When the lighting is switched on the
lamp next to the lighting touch con-
trol glows.
Operation
12

Filter operating hours counter
An indicator lamp shows when the
grease filter needs to be cleaned. The
operating hours counter for the grease
filter is set at the factory for a certain
number of hours but these can be
changed if required.
The operating hours counter for the re-
circulation micro-filter is set at the fac-
tory for an unlimited number of hours
but these can be changed if required.
After this set time has elapsed, the indi-
cator lamp next to the grease filter /
micro-filter touch control glows. The
grease filter must then be cleaned or
the micro-filter replaced by a new one.
After the grease filter has been cleaned
and put back in place or the micro-filter
has been replaced by a new one, the fil-
ter operating hours counter must be re-
set.
– To do this press the grease filter /
micro-filter touch control and hold for
about 4 seconds.
The indicator lamp will go out.
Reading the filter operating
hours counter
To check the percentage of the time set
already used:
– Use the On/Off touch control to
switch the fan on.
– Press the grease filter / micro-filter
touch control.
One or several of the indicator lamps
between the –/+touch controls will
flash.
The number of flashing lamps indicates
the percentage of operating time set al-
ready used up.
1 lamp = 25%
2 lamps = 50%
3 lamps = 75%
4 lamps = 100%
The number of operating hours used re-
mains in memory, even when the ap-
pliance is switched off or there is a
power cut.
Operation
13

Altering the filter operating
hours counter
You can set the operating hours
counter to suit the type of cooking you
do.
Select a short time if you roast or fry a
lot.
If you use very little fat for cooking, se-
lect a longer time.
If, however, you only cook occasionally
we recommend that you select a short
time because grease which has built
up gradually over a long period of time
will harden on the grease filters and
make cleaning more difficult.
Grease filters
The operating hours counter for the
grease filters is set to 30 hours. This
time can be lengthened or shortened.
You can choose from 20, 30, 40 or 50
hours.
– Use the On/Off touch control to
switch the fan off.
– Press the run-on option touch control
and the grease filter touch control at
the same time.
The indicator lamp for the grease filter
touch control and one of the lamps be-
tween the –/+touch controls will flash.
The lamps between the –/+touch con-
trols show the time which has been set:
1st lamp from left = 20 hours
2nd lamp from left = 30 hours
3rd lamp from left = 40 hours
4th lamp from left = 50 hours
– Use the –/+touch controls to select
the desired time.
– Confirm the procedure by pressing
the grease filter touch control.
If the procedure is not confirmed
within 4 minutes of programming
the steps, the cooker hood will auto-
matically revert to the “old” data.
Operation
14

Micro-filters
The micro-filter is needed for recircula-
tion mode. They are not used for
vented extraction.
As the cooker hood is set up ex-works
for vented extraction, the operating
hours counter for the micro-filter is set
to “unlimited”.
For recirculation mode the operating
hours counter needs to be set to the re-
quired time:
– Use the On/Off touch control to
switch the fan off.
– Press the run-on option touch control
and the micro-filter touch control at
the same time.
The indicator lamp for the micro-filter
touch control and one of the lamps be-
tween the –/+touch controls will flash.
The lamps between the –/+touch con-
trols show the time which has been set:
1st lamp from left = 120 hours
2nd lamp from left = 180 hours
3rd lamp from left = 240 hours
4th lamp from left = unlimited
– Use the –/+touch controls to select
the desired time.
– Confirm the procedure by pressing
the micro-filter touch control.
If the procedure is not confirmed
within 4 minutes of programming
the steps, the cooker hood will auto-
matically revert to the “old” data.
Operation
15

Cleaning and care
Before any cleaning or maintenance
work the cooker hood must be dis-
connected from the mains supply.
Ensure that:
- it is switched off at the fused spur
connection or
- it is switched off at the wall socket
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
appliance while maintenance or re-
pair work is being carried out.
Housing
Lacquered surfaces can be cleaned
using hot water to which a little mild
washing-up liquid has been added.
Dry with a soft cloth.
For stainless steel surfaces a mild non-
abrasive proprietary stainless steel
cleaner is suitable.
Never use cleaners which scour or
contain chlorine, acids or soda.
These would damage the surface of
the cooker hood.
Grease filters
Re-usable metal grease filters are fitted
which remove solid particles (oil, dust,
etc.) from the kitchen vapours, prevent-
ing soiling of the cooker hood.
The grease filters should be cleaned
regularly to avoid a build-up of fat, (ap-
prox. 3-4 weeks on average, but
sooner if necessary). Always clean the
filters immediately if the lamp for the
grease filter touch control comes on.
An over saturated filter is a fire
hazard.
– To take out the grease filters press
the filter retention clips in towards
the middle of the filter.
– Holding carefully, lower and remove
the filter.
Cleaning and care
16

– Clean the filters
– by hand: with a nylon brush in a
mild solution of warm water and
washing up liquid.
– in a dishwasher: place the filter
with the short side upright in the
lower basket, ensuring the spray
arm is not obstructed.
Depending on the cleaning agent
used, cleaning the grease filters in
a dishwasher can cause permanent
discolouration to the surface of the
filters. However, this will not affect
the functioning of the grease filters
in any way.
– After cleaning, leave the filters to dry
on an absorbent surface before put-
ting them back in place.
– When removing the filters for clean-
ing also clean off any residues of oil
or fat from the now accessible hous-
ing to prevent the risk of these catch-
ing fire.
When replacing the filters, make
sure that the clips are visible, facing
down towards the hob.
Should a filter be replaced upside
down, insert a small screwdriver
blade into the slits to disengage the
clip. Do not let the filter drop onto
the hob below.
– After putting the grease filters back
in place, press the grease filter touch
control for approx. 4 seconds to re-
set the operating hours counter.
Fitting / replacing the recircula-
tion micro-filters
For recirculation mode two micro-filters
have to be used in addition to the
grease filters. The micro-filters are de-
signed to absorb cooking odours and
are fitted in the canopy above the
grease filters.
– Before fitting the micro-filters the
grease filters must first be taken out,
(see previous section for instructions
on how to do this).
The micro-filters are supplied with fit-
ting instructions. Ensure these are care-
fully followed.
When fitting for the first time:
– Set the operating hours counter to
suit your requirements, (see “Oper-
ation - Altering the filter operating
hours counter”).
Always replace the filters immediately if
the lamp for the micro-filter touch con-
trol comes on, or if they are no longer
effective in absorbing kitchen odours.
They should, however, be replaced at
least every 6 months.
– After fitting new micro-filters, press
the micro-filter touch control for ap-
prox. 4 seconds to re-set the opera-
ting hours counter.
Cleaning and care
17

Changing a halogen light lamp
Before any cleaning or maintenance
work the cooker hood must be dis-
connected from the mains supply.
Ensure that:
- it is switched off at the fused spur
connection or
- it is switched off at the wall socket
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
appliance while maintenance or re-
pair work is being carried out.
When in use the halogen lamps
become very hot. Do not touch im-
mediately as they remain hot for
some time after being switched off.
You must not touch the surface of a
halogen lamp when changing it as
this will damage it. Please follow the
manufacturer’s instructions.
– To change the halogen lamp first
remove lamp cover b.
– The halogen lamp cis fitted to a
push-in connection socket. To re-
place, pull out the old lamp and fit a
new one.
– Replace the lamp cover b
carefully, making sure it engages se-
curely in position.
Never use the lighting without the
lamp cover bin place as it has a fil-
ter designed to cut out harmful rays.
