isolated from the electricity supply
when:
– it is switched off at the wall socket
and the plug removed. (Do not pull
on the cable, only on the plug), or
– the fuse from the fused spur connec-
tion unit is withdrawn or,
– the mains fuse is withdrawn, or
– the screw-out fuse is removed in
countries where this is applicable.
Ensure power is not supplied to
the appliance 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 overheating).
Use
Do not let small children play with
the appliance or its controls or
operate it. Supervise its use by the elderly or infirm.
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 filter. 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 using the hob, 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 ignite and could set the cooker hood on
fire.
Do not use the cooker hood with-
out the grease filters in place.
This way you will avoid the risk of
grease and dirt getting into the appliance and hindering its smooth operation.
The filters should be regularly
cleaned, or changed, as appropriate. Saturated filters are 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.
In countries where there are areas
which may be subject to infestation 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 may be caused by cockroaches or other vermin will not be
covered by the appliance guarantee.

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:
– 450 mm above electric hobs and
cookers
– 650 mm above gas hobs and
cookers
– 650 mm above an open grill from our
range
When fitted above an open grill the
cooker hood must not be used in
recirculation mode.
For non-Miele cooking appliances main-
tain the safety distance as recommended by the manufacturer 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 greater distance.
If exhaust air is to be extracted into
a chimney or ventilation duct no
longer used for other purposes, seek
professional advice.
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 from the
Miele 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.
6
Warning and Safety instructions
When using the cooker hood in ex-
traction mode 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 in which the
appliance is installed and from neighbouring rooms, which these types of
heater need for combustion.
They could also draw exhaust air back
in from chimneys or ducting in contravention of fire safety regulations.
In order to ensure safe operation, and to
prevent 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 maximum 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.
Appliances with external fans
For appliances with an external fan
motor fitted (EXT models) the connection of the two units must be made
using the connection cable and the
plug connectors. Make sure the correct
combination of the two appliances has
been selected.
Separate 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
liable for damage caused by noncompliance with these Warning and
Safety instructions.
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 operated in recirculation mode (with active charcoal filter) then the above restrictions do not
apply.

Functional description
Functional description
The cooker hood works with
. . . air extraction
The air is drawn in and cleaned by the
grease filters and directed outside.
The cooker hood is fitted with a
non-return flap.
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 vapours to be blown directly outside.
. . . air recirculation:
The air is drawn in and cleaned first by
grease filters and then cleaned by active charcoal filters. The cleaned air is
then recirculated back into the kitchen
through a vent in the top of the cooker
hood extension piece.
Before using the cooker hood for
the first time, ensure that the active
charcoal filters are in place, see
section on "Cleaning and care".
. . . an external fan
The EXT models are designed to be
connected to an external fan located
outside the room.
The external fan is connected to the
cooker hood by means of a control
cable and is operated by the control
panel on the cooker hood.

To do this, press the grease filter
touch control and hold for about 3
seconds.
The indicator lamp for the control will
go out.
For recirculation mode the operating
hours counter needs to be set to the required time.
Reading the filter operating hours
counter
To check the percentage of time set already used:
Use the On/Off touch control to
switch the fan on.
Press the grease filter / active charcoal filter touch control.
One or several of the indicator lamps
for the – /+ touch controls will flash.
The indicator lamp for the active charcoal filter control will light up after the

filters must then be replaced with new
ones.
The filter operating hours counter must
then be re-set.
Press the active charcoal filter touch
control for about 3 seconds.
The indicator lamp for the control will
go out.
The number of flashing lamps shows
the percentage of the operating time
which has already been used up.
1 lamp = 25 %
2 lamps = 50 %
3 lamps = 75 %
4 lamps = 100 %
The number of operating hours used remains in the memory, even when the
appliance is switched off or there is a
power cut.
13
Operation
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,
select a longer time.
– If you only cook occasionally we re-
commend 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.
Altering the grease filter
operating hours counter
The operating hours counter for the
grease filters is set at 30 hours. This
can be lengthened or shortened. You
can choose from 20, 30, 40 or 50 hours.
The indicator lamp for the grease filter
touch control and one of the – /+ touch
control lamps will flash.
The – /+ touch control lamps show the
time which has been set:
1st lamp from the left = 20 hours
2nd lamp from the left = 30 hours
3rd lamp from the left = 40 hours
4th lamp from the left = 50 hours
Use the – /+ touch controls to select
the desired time.
Confirm the selection by pressing
the grease filter touch control.
If the procedure is not confirmed
within 4 minutes of programming
the steps, the cooker hood will automatically revert to the "old" data.
Press the On/Off touch control to
switch the fan off.
