Warning and safety instructions
This appliance meets statutory
safety requirements. Inappropriate
use could, however, lead to risk of
accidents to the user and damage
to the appliance.
Read the operating instructions be-
fore using this machine for the first
time. They contain important infor-
mation about the safety, use and
maintenance of the machine. This
will avoid the risk of accidents and
damage to the machine.
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 of
the machine.
Appropriate use of the cooker
hood
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.
Technical 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. 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 import-
ant that this basic safety requirement is
tested by a qualified electrician. The
manufacturer cannot be held respon-
sible for the consequences of an inade-
quate earthing system (eg electric
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.
Warning and safety instructions
4

The appliance is only completely
isolated from the electricity supply
when, depending on the type of con-
nection:
- it is switched off at the fused unit or
the fuse is withdrawn
– it is switched off at the wall socket
and the plug removed
To remove the plug, pull on the plug it-
self, not the cable.
– the mains fuse is withdrawn
– or the screw-out fuse is removed. En-
sure current is not restored 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 (eg danger of overheating).
Use of the appliance
Never use an open flame beneath
the cooker hood. To avoid the
danger of fire, do not flambé or grill
dishes.
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 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.
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 ap-
pliance and hindering its smooth oper-
ation.
Warning and safety instructions
5

The filters should be regularly
cleaned, or changed, as appropri-
ate.
Saturated filters are a fire hazard.
Under no circumstances use a
steam cleaner to clean this ap-
pliance.
Pressurised steam could give rise to a
short circuit or cause permanent dam-
age to the surface and components, for
which the manufacturer of the cooker
hood cannot accept any responsibility.
Installation
The distance between the top of
the hob and the bottom of the
cooker hood must measure at least:
– 55 cm above electric hobs
– 65 cm above gas hobs
The distance of 65 cm between
the cooker hood and a gas hob is
a minimum, which is only permissible if
the nominal heat ratings given in the
table below are not exceeded:
Gas cooker maximum
nominal rating
one burner 2.7 kW
all burners 7.5 kW
oven 3.5 kW
Gas hob maximum
nominal rating
one burner 3.5 kW
all burners 10.3 kW
Gas hob with ceramic cover plate
The data given for the maximum nominal (heat)
ratings do not apply to a gas hob with a ceramic
cover plate. In this case it is essential to refer to
the hob manufacturer’s data.
Safety regulations prohibit the fit-
ting of a cooker hood over solid
fuel stoves.
All ducting, pipework and fittings
must be of non-flammable mate-
rial. 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.
If exhaust air is to be extracted into
a chimney or ventilation duct no
longer used for other purposes, take
professional advice.
Warning and safety instructions
6

When using the cooker hood at the
same time as another heating ap-
pliance which depends on the air in the
room (eg gas, oil or coal fired heaters,
continuous flow or other water heaters,
gas cooker, gas hob or gas oven), spe-
cial care must be taken as the action of
the cooker hood extracts air from the
room, which these type of heaters need
for combustion.
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 (4pa) 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 en-
suring that the extractor can only be
switched on when the heating appliance
is switched off or vice-versa.
NB: The overall ventilation condition of
the dwelling must be taken into ac-
count. 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 recir-
culation mode only, with active char-
coal filters, these restrictions do not
apply.
Disposal of your old appliance
Ensure that disconnection from the
mains supply is carried out by a
competent person. Render any plug
useless. Cut off the cable directly be-
hind the appliance to prevent misuse.
The manufacturer cannot be held re-
sponsible for damage caused by
non-observance of these instruct-
ions.

The cooker hood can be set up to oper-
ate by either air extraction or by air re-
circulation.
The appliance is supplied from the fac-
tory ready for connection as an extrac-
tor.
Air extraction
Air is drawn in through the grease fil-
ters e, cleaned and directed outside.
The appliance is fitted with a non-return
air flap. When the hood is not in oper-
ation, the non-return air flap is closed.
No exchange of air can take place be-
tween the air in the room and the air
outside.
Air recirculation
Air is drawn in through the grease fil-
ters and then through the active char-
coal filters for cleaning. It then passes
back into the kitchen (see section “Air
recirculation”).

Cleaning and care
Before carrying out maintenance
work, the cooker hood must be dis-
connected from the mains supply.
ensure that, depending on the con-
nection:
- it is switched off at the fused unit
or the fused unit switch is with-
drawn, or
- it is switched off at the wall socket
and the plug removed (do not pull
on the cable, only on the plug, or
- the mains fuse is withdrawn; or
- the screw-out fuse is removed (in
countries where this is applicable).
Ensure curent is not restored to the
appliance while maintenance or re-
pair work is being carried out.
Housing
The cooker hood housing can be
cleaned using hot water with a little
mild detergent. Dry using a soft cloth.
Never use cleaning agents contain-
ing soda, acids, chlorides or ab-
rasive substances, as these can
damage the surface material.
Grease filters
The re-usable metal grease filters in the
appliance remove solid particles from
the kitchen vapours (grease, dust, etc)
preventing soiling of the cooker hood.
Always clean the grease filters when
they are visibly saturated with grease,
or when their operating efficiency is re-
duced. They should be cleaned at
least every one to two months.
An oversaturated filter is a fire ha-
zard!
To remove the grease filters, push
the filter retention clips in towards
the middle.
Take the grease filters out and clean.
By hand: with a scrubbing brush in hot
water with detergent.
In the dishwasher: Place the filters
with the short side upright in the
lower basket, ensuring the spray
arm is not obstructed.
After cleaning, leave the filters to dry
for a while on an absorbant surface
before putting 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.
Cleaning and care
11

Changing the lamp and the
starter
Disconnect the cooker hood by
– switching off the mains switch
– withdrawing the mains fuse
– removing the screw-out fuse.
Lift the slide lug of the lamp cover
and slide to the right to remove.
Change the fluorescent lamp (15 W)
or the starter.
Inserting and removing active
charcoal filters
If the cooker hood is connected for air
recirculation, the active charcoal filters
must be installed in addition to the
grease filters. These filters absorb
odours from the kitchen.
Remove the grease filters.
Secure the active charcoal filters
using the screws enclosed.
The active charcoal filters should be re-
placed when they are no longer func-
tioning efficiently, or at least every three
to four months.
Put back the grease filters.

Danger of toxic fumes
Please follow the advice in the sec-
tion “Warning and safety instruct-
ions” very carefully.
The cooker hood should be in-
stalled acording to local regulations.
Seek approval from the buildings in-
spector where necessary.
Connection
– The extraction ducting should be as
short and straight as possible.
– Use large radius bends. Narrow
bends reduce the efficiency of the
cooker hood.
– Pipes made from non-flammable ma-
terials only may be used for extrac-
tion connection.
– If the extraction ducting is to be laid
horizontally, it should slope down-
wards away from the cooker hood
with a minimum incline of 1 cm per 1
metre of ducting to prevent con-
densed water from running back into
the appliance.
Calculating the extraction ducting
A pipe of diameter 120 mm (100 mm)
should guarantee trouble-free extrac-
tion by the cooker hood up to a total
pipe length of 34m (16m).
Determine the total pipe length as fol-
lows:
Measure the total length of the ex-
traction ducting to be used.
Add the appropriate equivalent
length of additional piping to this fig-
ure, according to the number and
type of bends (see table).

Important!
If the exhaust ducting is to run through
cool rooms, ceiling space etc where
there may be great variations in tem-
perature between the different areas,
the problem of sweating or condensa-
tion will need to be addressed.
The exhaust ducting will need to be
suitably insulated.
In addition to insulating the exhaust
ducting it may be necessary in some
cases to install a suitable condensate
trap to collect and evaporate any con-
densate which may occur.
Please note that the condensate
trap should be installed vertically
and as directly above the exhaust
socket of the cooker hood as
possible.

Connection for air recirculation
If site conditions are not suitable for the
cooker hood to be used for air extrac-
tion, the appliance must be converted
for recirculation.
The following parts will be required:
– Conversion kit from extraction to re-
circulation (only for units or cooker
hood shafts which do not reach the
ceiling)
– Active charcoal filters
These parts are available from your
Miele Dealer or from the Miele Spare
Parts Department.
Connection –
for units or cooker hood shafts
which do not reach the ceiling
Saw out an opening in the cupboard.
From above, place the hose with the
directional grille through the hole in
the unit onto the exhaust connection
of the cooker hood so that the air out-
let points in the desired direction.
