This appliance complies with all
relevant local and national safety
requirements. Inappropriate use
can, however, lead to personal injury
and damage to property.
To avoid the risk of accidents and
damage to the appliance, please
read these instructions carefully
before using it for the first time. They
contain important information on the
safety, installation, use and
maintenance of the appliance.
Keep these instructions in a safe
place and ensure that all users are
familiar with the contents. Pass them
on to any future owner of the

appliance could get damaged. Consult
a qualified electrician if in any doubt.
The electrical safety of this
appliance can only be guaranteed
when continuity is complete between
the appliance and an effective earthing
system which complies with local and
national safety regulations. It is most
important that this basic safety
requirement is present and tested
regularly, and where there is in any
doubt, the household wiring system
should be inspected by a qualified
electrician. The manufacturer cannot be
held liable for the consequences of an
inadequate earthing system (e.g.
electric shock).
Installation, maintenance and
repair work may only be carried out
by a suitably qualified and competent
person in strict accordance with
national and local safety regulations.
Repairs and other work by unqualified
persons could be dangerous. The
manufacturer cannot be held liable for
unauthorised work.

in mobile installations such as
ships if a risk assessment of the
installation has been carried out by a
suitably qualified engineer.
Warning and Safety instructions
4

The appliance is only completely
isolated from the electricity supply
when:
–it is switched off at the isolator,
–the fuse from the fused spur
connection unit is withdrawn,
–the mains fuse is disconnected, or
–the screw-out fuse is removed (in
countries where this is applicable).
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).
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.
These models may only be combined
with a Miele external motor.
Use
Never use an open flame beneath
the cooker hood. To avoid the
danger of fire, do not flambé or grill
over an open flame under the cooker
hood. 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.
The burner should be switched off
before taking a pan off the hob, even
for brief periods.
Regulate the flames so that they do not
extend beyond the base of the pan.
If flames are not covered by a pan,
excessive heat can build up in the
cooker hood with the risk of damage.
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
ignite and could set the cooker hood on
fire.
Do not use the cooker hood without
the grease filter and outer filter 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. See "Cleaning and care".
Do not use a steam-cleaner to
clean this appliance. Pressurised
steam could reach the electrical
components and cause a short circuit.
Warning and Safety instructions
5

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 guarantee.
Safety with children
The appliance is only intended for
use by adults who have read these
instructions.
The appliance is not a toy! Keep
children well away from the
appliance at all times, and do not allow
them to play with it or use the controls.
They will not understand the potential
dangers posed by it. They should be
supervised whenever you are working
in the kitchen.
Older children may use the
appliance only when its operation
has been clearly explained to them and
they are able to use it safely,
recognising the dangers of misuse.
Please be aware that on
appliances with halogen lighting,
the lamps will get very hot during use
and remain hot for some time after
switching off. To safeguard against
burning, keep children well away from
the lamps at all times.
Packaging, e.g. cling film,
polystyrene and plastic wrappings,
must be kept out of the reach of babies
and young children. Danger of
suffocation. Dispose of or recycle all
packaging safely as soon as possible.
Installation
The minimum safety distances
between the top of a cooker or hob
and the bottom of the cooker hood are
as follows, unless a greater distance is
specified by the manufacturer of your
cooking appliance:
–550 mm above electric hobs
and cookers,
–650 mm above gas hobs and
cookers,
–650 mm above an open grill or deep
fat fryer.
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.
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
connected 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, seek
professional advice.
Warning and Safety instructions
6

Using at the same time as other
heating appliances that depend on
the air from the room
Warning - danger of toxic fumes
Great care should be taken when
using the cooker hood at the same
time and in the same room or area of
the house as another heating appliance
which depends on the air in the room.
Such appliances include gas, oil, wood
or coal-fired boilers and heaters,
continuous flow or other water heaters,
gas hobs, cookers or ovens which draw
air in from the room and duct exhaust
gases out through a chimney or
extraction ducting.
When used in extraction mode, with or
without an external motor fitted, the
appliance draws air in from the room in
which it is installed and from
neighbouring rooms.
If there is insufficient air, an
underpressure will occur. The heating
appliance may be starved of oxygen,
impairing combustion.
Harmful gases could be drawn out
of the chimney or extraction ducting
back into the room, with potentially
fatal consequences.
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.
A ventilation brick alone is not generally
sufficient to ensure safe ventilation.
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.
Warning and Safety instructions
7

One of the following technical
measures may be necessary to ensure
safe operation.
–If the only way of ensuring adequate
ventilation is via an open window, a
window contact switch should be
fitted to ensure that the cooker hood
can only operate when the window is
opened sufficiently. A window
contact switch kit is available from
good builders' merchants.
Take care when ventilating the room
through an open window that
ventilation is not impaired by a
closed blind or curtain.
– The cooker hood can be set up to
automatically switch on an air intake
fan or open a motorised inlet flap
when it is switched on.
– The cooker hood can be set up to
automatically switch off a heating
appliance which also depends on
the air from the room when it is
switched on.
The Miele DSM 400 control module
offers the possibility of combining other
components with the cooker hood (see
"Operation with Control module DSM
400").
It is available to purchase as an
optional extra.
If in any doubt, the advice of a
competent builder or, for gas, a
"Corgi" installer, must be sought.
The manufacturer cannot be held
liable for damage caused by
non-compliance with these Warning
and Safety instructions.
Warning and Safety instructions
8

The cooker hood works with
. . . air extraction:
The air is drawn in and cleaned by the
stainless steel outer filter and the
grease filter, and then directed outside.
The cooker hood is fitted with a
non-return flap, which 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.
. . . an external fan:
( ...EXT models only)
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 controls
on the cooker hood.

Altering the filter operating hours
counter
The operating hours counter for the
grease filter is set at the factory for 30
hours. The time set can be lengthened
or shortened to suit the type of cooking
you do. You can choose 20, 30, 40 or
50 hours.
–Select a short time if you roast or fry
a lot.
– If you use very little fat for cooking,
select a longer time.

Cleaning the grease filter and the
outer filter in the dishwasher
^Place the filters with the short side
upright in the lower basket, and wash
on a 65° programme using a mild
dishwasher detergent, ensuring the
spray arm is not obstructed.
Avoid alkaline dishwasher detergents
(with a pH value higher than 7).
Depending on the cleaning agent
used, cleaning the filters in a
dishwasher can cause permanent
discolouration to the surface.
However, this will not affect the
functioning of the filters in any way.
