Warning and Safety instructions
8
Using at the same time as another heating appliance that depends on the air
from the room
Danger of toxic fumes!
Great care should be taken when using the cooker hood in the
same room or the same area of the house at the same time as
another heating appliance that depends on the air from the room.
Such heating appliances draw in air from the room and duct
exhaust gases out to the open air through a chimney or extraction
ducting. They include gas, oil, wood and coal-fired boilers and
heaters, continuous flow or other water heaters, gas hobs and
ovens.
The cooker hood draws in air from the kitchen and from
neighbouring rooms. This applies to the following modes of
operation:
- extraction mode,
- recirculation mode with a recirculation box installed outside the
room.
If there is insufficient air, an underpressure will occur. The heating
appliance may be starved of oxygen. This impairs combustion.
Harmful gases could be drawn from the chimney or extraction
ducting back into the room.
Risk of death!

Warning and Safety instructions
9
In order to ensure safe operation and to prevent gases given off by
the heating appliance from being drawn back into the room, when
the cooker hood and the heater are both operated simultaneously,
an underpressure in the room of 0.04mbar (4Pa) is the maximum
permissible.
Sufficient ventilation can be maintained by air inlets which cannot
be blocked, e.g. in windows, doors and outside wall vents. The
cross-section of the inlet openings must enable sufficient
ventilation. 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 qualified gas fitter should be sought.
If the cooker hood is being operated in recirculation mode,
whereby the air is redirected into the room in which it is installed,
the above restrictions do not apply.

Warning and Safety instructions
10
Correct use
 Never use a naked flame beneath the cooker hood. To avoid the
danger of fire, do not flambé or grill over a naked flame.
When switched on, the cooker hood could draw flames into the filter.
Fat deposits could ignite, presenting a fire hazard.
 The cooker hood can become damaged when exposed to
excessive heat.
– When using the cooker hood over a gas hob, ensure that any
burners in use are always covered by a pan. Switch the cooking
zone off when a pan is removed, even for a short time.
– Select a pan which is suitable for the size of the burner.
– Regulate the flame so that it does not burn up the sides of the
pan.
– Avoid overheating the pan (e.g. when cooking with a wok).
 Always switch the cooker hood on when a cooking zone is in use,
otherwise condensation may collect in the hood, which could cause
corrosion.
 Overheated oil and fat can ignite, causing fire damage to the
cooker hood.
When cooking with oil or fat, chip pans and deep fat fryers etc, do
not leave the pans unattended. Similarly, never leave an open grill
unattended when grilling.

Warning and Safety instructions
11
 Do not use the cooker hood without the filters in place. This way
you will avoid the risk of grease and dirt getting into the appliance
and hindering its smooth operation.
 The cooker hood can get very hot during cooking due to heat
rising from the hob.
Do not touch the housing or the grease filters until the cooker hood
has cooled down.
 This cooker hood is not suitable for placing objects on.
Correct installation
 Refer to the cooker or hob manufacturer's instructions as to
whether a cooker hood may be operated above the cooker/hob.
 Safety regulations prohibit the fitting of a cooker hood over solid
fuel stoves.
 An insufficient safety distance between the hob and the cooker
hood can result in damage to the cooker hood.
The minimum safety distances between the top of the cooker or hob
and the bottom of the cooker hood given in the “Installation” section
of this booklet must be maintained, unless the hob manufacturer
states that a greater safety distance is required.
If more than one cooking appliance is fitted beneath the cooker
hood, and they have different minimum safety distances to the
cooker hood, select the greater distance.
 The distances given in “Installation” must be observed when
fitting the cooker hood.

Warning and Safety instructions
12
 Exhaust ducting must be of non-inflammable material. Suitable
material is available from Miele specialist dealers or the Miele Spares
Dept.
 The appliance must not be connected to a chimney or 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.
Cleaning and care
 There is a risk of fire if the cooker hood is not cleaned as
described in these operating instructions.
 Do not use a steam cleaning appliance to clean this appliance.
The steam could reach electrical components and cause a short
circuit.
Accessories
 Only use genuine original Miele accessories and spare parts with
this appliance. Using accessories or spare parts from other
manufacturers will invalidate the warranty and Miele cannot accept
liability.

Caring for the environment
13
Disposal of the packing
material
The packaging is designed to protect
the appliance from damage during
transportation. The packaging materials
used are selected from materials which
are environmentally friendly for disposal
and should be recycled.
Recycling the packaging reduces the
use of raw materials in the
manufacturing process and also
reduces the amount of waste in landfill
sites.
Disposing of your old
appliance
Electrical and electronic appliances
often contain valuable materials. They
also contain specific materials,
compounds and components, which
were essential for their correct function
and safety. These could be hazardous
to human health and to the environment
if disposed of with your domestic waste
or if handled incorrectly. Please do not,
therefore, dispose of your old appliance
with your household waste.
Please dispose of it at your local
community waste collection / recycling
centre for electrical and electronic
appliances, or contact your dealer or
Miele for advice. You are also
responsible (by law, depending on
country) for deleting any personal data
that may be stored on the appliance
being disposed of. Please ensure that
your old appliance poses no risk to
children while being stored prior to
disposal.

Modes of operation
16
Depending on the model of the cooker
hood, the following options are
available:
Extraction mode
The air is drawn in and cleaned by the
grease filters and directed outside.
Non-return flap
The non-return flap is designed to
prevent the exchange of room and
outside air taking place when the
cooker hood is switched off.
The flap is closed when the cooker
hood is switched off.
When the cooker hood is switched on,
the non-return flap opens for the
cooking vapours to be blown directly
outside.
If the on-site ventilation system does
not have a non-return flap, the non-
return flap supplied must be fitted in the
exhaust socket in the motor unit.
Recirculation mode
(recirculation mode cooker hoods
require a conversion kit and charcoal
filter, see “Technical Data”)
The air is drawn in and cleaned first by
the grease filters and then by a charcoal
filter. The cleaned air is then
recirculated back into the kitchen.

Operation
17
Switching the fan on
For light to heavy cooking vapours and
odours, select from power levels 1 to 3.
For short periods of cooking food with
intensive vapours and a strong aroma,
e.g. when searing meat, select Booster
setting B.
Switch the fan on with the fan switch
 and select the power level you
want.
Switching the fan off
It is advisable to run the fan for a few
minutes after cooking has finished to
neutralise any lingering vapours and
odours in the air.
Turn the fan switch to 0.
Switching the hob lighting on/
off
The hob lighting can be switched on
and off independently of the fan.
Use the lighting switch  to switch
the hob lighting on (1) or off (0).

Energy saving tips
18
This cooker hood operates very
efficiently and economically. The
following will help you to save even
more energy when using it:
– Ensure that there is sufficient
ventilation in the kitchen when
cooking. In extraction mode, if there
is insufficient air flow the cooker
hood cannot operate efficiently and
this causes increased operating noise
levels.
– Always cook with the lowest possible
setting. This produces fewer cooking
vapours, so you can use a lower
cooker hood power level and
therefore benefit from reduced
energy consumption.
– Check the power level selected on
the cooker hood. A lower power level
is generally sufficient for the majority
of cooking. Only use the Booster
setting when necessary.
– When a large volume of cooking
vapours is being produced, switch to
a high power level in good time. This
is more efficient than operating the
cooker hood for longer to try to
capture cooking vapours which have
already been distributed throughout
the kitchen.
– Make sure that you switch the cooker
hood off after use.
– Clean or change the filters at regular
intervals. Heavily soiled filters reduce
performance, increase the risk of fire
and are unhygienic.

Cleaning and care
19
Before proceeding with any
maintenance or cleaning task, the
cooker hood must be disconnected
from the power supply, see “Warning
and safety instructions”.
Housing
General information
The surfaces and controls are
susceptible to scratches and
abrasion.
Please observe the following
cleaning instructions.
All external surfaces and controls can
be cleaned using hot water with a
small amount of washing-up liquid
applied with a well wrung-out soft
sponge or cloth.
Make sure that water does not
get into the cooker hood.
Only clean the area of the controls
with a damp cloth.
Then wipe the surfaces dry using a
soft cloth.
Do not use:
– cleaning agents containing soda,
acids, chlorides or solvents,
– abrasive cleaning agents, e.g.
powder cleaners or cream cleaners
and abrasive sponges, as well as pot
scourers or sponges which have
been used previously with abrasive
cleaning agents.
Important for appliances with
stainless steel surfaces
(This information does not apply to the
controls).
Stainless steel surfaces can be
cleaned with a proprietary non-
abrasive cleaning agent designed
specifically for use on stainless steel.
To help prevent re-soiling, a
proprietary conditioning agent for
stainless steel (available from Miele)
can also be used.
Apply sparingly with a soft cloth.
Important for appliances with
lacquered housing
Please observe the general notes on
cleaning earlier in this section.
Minor scratches on the surface are
inevitable when cleaning the housing.
Depending on the lighting in the
kitchen, this may negatively affect the
appliance's appearance.

Cleaning and care
20
Important for the controls
Do not leave soiling on the controls
for any length of time.
Otherwise they may suffer
discolouration or damage.
Remove soiling straight away.
Please observe the general notes on
cleaning earlier in this section.
Do not use stainless steel cleaning
agents on the controls.
Grease filters
Fire hazard!
Oversaturated grease filters are a fire
hazard.
Clean the grease filters at regular
intervals.
The re-usable metal grease filters in the
appliance remove solid particles
(grease, dust, etc.) from the kitchen
vapours, preventing soiling of the
cooker hood.
The grease filters must be cleaned at
regular intervals.
Heavily soiled grease filters hinder air
extraction and will lead to increased
levels of soiling in the cooker hood
and in the kitchen.
Cleaning interval
Accumulated grease solidifies over a
longer period of time and makes
cleaning more difficult. The grease
filters should therefore be cleaned every
3 to 4 weeks.
Removing a grease filter
When handling a grease filter, be
careful not to drop it.
This can result in damage to the filter
and the hob below.
Make sure you hold the filter securely
at all times when handling it.
To take out a grease filter, release the
locking clip on the filter, lower the
filter approx. 45°, unhook it at the
back and remove it.
Cleaning the grease filters by hand
Clean the filters with a soft nylon
brush in a mild solution of hot water
and a small amount of washing-up
liquid. Do not use “neat” washing up
liquid.
