Disposal of the packing
material
The transport and protective packing
has been selected from materials which
are environmentally friendly for
disposal, and can normally be
recycled.
Ensure that any plastic wrappings,
bags etc. are disposed of safely and
kept out of the reach of babies and
young children. Danger of suffocation!
Rather than just throwing these
materials away, please ensure that they
are recycled.
Disposal of your old appliance
Electrical and electronic appliances
often contain materials which, if
handled or disposed of incorrectly,
could be potentially hazardous to
human health and to the environment.
They are, however, essential for the
correct functioning of your appliance.
Please do not therefore dispose of it
with your household waste.
Please dispose of it at your local
community waste collection / recycling
centre or contact your dealer for
advice. Ensure that it presents no
danger to children while being stored
for disposal.
It should be unplugged or
disconnected from the mains electricity
supply by a competent person.
Take care not to damage the pipework
at the back of it before or during
transportation to an authorised
collection depot.
In this way, refrigerant in the pipework
and oil in the compressor will be
contained, and will not leak out into the
environment.

Technical safety
~Before setting up the appliance,
check it for any externally visible
damage. Do not install and use a
damaged appliance.
A damaged appliance is dangerous.
~If the connection cable is faulty it
must only be replaced by a service
technician authorised by the
manufacturer to protect the user from
danger.
~This appliance contains the coolant
Isobutane (R600a), a natural gas which
is environmentally friendly. Although it
is flammable, it does not damage the
ozone layer and does not increase the
greenhouse effect. The use of this
coolant has, however, led to a slight
increase in the noise level of the
appliance. In addition to the noise of
the compressor, you might be able to
hear the coolant flowing around the
system. This is unavoidable, but does
not have any adverse effect on the
performance of the appliance. Care
must be taken during transportation
and setting up of the appliance that no
parts of the cooling system are
damaged. Leaking coolant can
damage the eyes.
In the event of any damage:
- avoid open flames and anything
which creates a spark,
- disconnect from the mains,
- air the room in which the appliance is
located for several minutes and
- contact the Service Department for
advice.
~The more coolant there is in an
appliance, the larger the room it should
be installed in. In the event of a
leakage, if the appliance is in a small
room, there is the danger of
combustible gases building up.
For every8gofcoolant at least 1 m3of
room space is required. The amount of
coolant in the appliance is stated on the
data plate inside the appliance.
~Safe operation of the appliance is
only assured if it has been installed and
connected in accordance with these
operating and installation instructions.
~Before connecting the appliance,
make sure that the connection data on
the data plate (voltage and connected
load) match the mains electricity
supply.
This data must correspond in order to
avoid the risk of damage to the
appliance. Consult a qualified
electrician if in any doubt.
~Do not connect the appliance to the
mains electricity supply by a
multi-socket unit or an extension lead.
These do not guarantee the required
safety of the appliance (e.g. danger of
overheating).
Warning and Safety instructions
8

~The electrical safety of this
appliance can only be guaranteed
when continuity is complete between it
and an effective earthing system which
complies with current local and national
safety regulations. It is most important
that this basic safety requirement is
present and tested regularly, and
where there is any doubt, the
household wiring system should be
inspected by a qualified electrician.
The manufacturer cannot be held liable
for damage or injury caused by the lack
of or inadequacy of an effective
earthing system (e.g. electric shock).
~Installation, maintenance and
repairs may only be carried out by a
suitably qualified and competent
person in strict accordance with current
national and local safety regulations.
Repairs and other work by unqualified
persons could be dangerous. The
manufacturer cannot be held liable for
unauthorised work.
~While the appliance is under
guarantee, repairs should only be
undertaken by a service technician
authorised by the manufacturer.
Otherwise the guarantee will be
invalidated.
~The appliance must be isolated from
the electricity supply during installation,
maintenance and repair work.
The appliance is only completely
isolated from the electricity supply
when:
–it has been switched off at the wall
socket and the plug has been
withdrawn, or
–the fuse from the fused spur
connection unit has been withdrawn,
or
–the mains fuse has been
disconnected, or
– the screw-out fuse has been
removed (in countries where this is
applicable).
~Faulty components must only be
replaced by genuine Miele original
spare parts. The manufacturer can only
guarantee the safety of the appliance
when Miele replacement parts are
used.
~This appliance may only be used in
mobile installations such as ships if a
risk assessment of the installation has
been carried out by a suitably qualified
engineer.
~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.
Warning and Safety instructions

Correct use
~Never store explosive materials in
the appliance or any products
containing propellants (e.g. spray
cans). Thermostats switching on may
produce sparks which could present a
fire hazard. Flammable compounds
could explode.
~Do not operate any electrical
equipment (e.g. an electric ice-cream
maker) inside the appliance. Danger of
sparking and explosion.
~If storing alcohol with a high
percentage proof, make sure it is tightly
closed and stored upright.
Danger of explosion.
~Observe the "use by" dates given on
food to avoid the risk of food poisoning.
Storage times will depend on several
factors, including the freshness and
quality of the food as well as the
temperature at which it is stored. Follow
the instructions given on food
manufacturer's packaging on storage
conditions required, as well as the "use
by" date.
~Do not use sharp edged objects to
–remove frost and ice,
–separate food which has become
frozen.
They will damage the evaporator,
causing irreversible damage to the
appliance.
~Do not use defrosting sprays or
de-icers, as they might contain
substances which could damage the
plastic parts or which could cause a
build-up of gases and pose a danger to
health.
~Do not use any oils or grease on the
door seal, as these will cause the seal
to deteriorate and become porous with
time.
~Do not store cooking oil in the
refrigerator door. Traces of oil can
cause stress cracks to occur in the
plastic components in the door.
~Do not block the ventilation gaps in
the appliance as this would impair the
efficiency of the appliance, increase the
electricity consumption and could
cause damage to the appliance.
~The appliance is designed for use
within certain climate ranges (ambient
temperatures), and should not be used
outside this range. The climate range
for your appliance is stated on the data
plate inside the appliance.
Installing it in a room with too low an
ambient temperature, e.g. a garage,
will lead to the appliance switching off
for longer periods so that it cannot
maintain the required temperature.
~Do not use a steam-cleaning
appliance to clean this appliance.
Steam could reach the electrical
components and cause a short circuit.
Warning and Safety instructions
10

Disposal of your old appliance
~Before disposing of an old
appliance, first make the door latch or
lock unusable.
This way you will prevent children from
accidentally locking themselves in and
endangering their lives.
~Be careful not to damage any part of
the pipework whilst awaiting disposal,
e.g. by
–puncturing the refrigerant channels
in the evaporator.
–bending any pipework.
– scratching the surface coating.
Splashes of refrigerant can damage the
eyes.
The manufacturer cannot be held
liable for damage caused by
non-compliance with these Warning
and safety instructions.

Use Only open the doors when
necessary and for as short a time
as possible.
Frequent opening of the doors for
long periods will cause a loss of
coldness.
Store food in an organised way. If food is not stored in an
organised way, searching for an
item will mean the door is open for
longer.
Allow hot food and drinks to cool
down before placing them in the
appliance.
Placing hot food in the appliance
will cause the compressor to run
for a long time, as the appliance
will have to work harder to lower
the temperature.
Store food covered or packaged. The evaporation or condensation
of liquids will cause a loss of
coldness in the refrigerator.
Place frozen food in the
refrigerator to defrost.
Do not over-fill the appliance to
allow air to circulate.
Defrosting Defrost the freezer compartment
when a layer of ice 0.5 cm thick
has built up.
A layer of ice hinders the cold
from reaching the frozen food, and
causes an increase in energy
consumption.
How to save energy
12

Before using for the first time
The stainless steel trim to the interior
shelves and the door shelves has a
layer of protective foil to prevent
damage during transportation. Please
remove this carefully after installation.
^Clean the inside of the appliance and
the accessories with lukewarm water
and a little washing-up liquid, and
then dry with a soft cloth.
Important:
To ensure the correct functioning of
the appliance, let it stand for
between 1½ and 2 hours after
transporting it to its final location
before connecting it to the mains.
Switching on
^Press the On/Off button. The
temperature display will light up.
The appliance begins to cool down,
and the temperature required shows in
the temperature display.
The interior light will come on when the
door is opened.
Switching off
^Press the On/Off button until the
temperature display goes out.
The cooling system is switched off.
Switching off for longer
periods of time
If the appliance is not going to be used
for a longer period of time, e.g. whilst
on holiday:
^switch the appliance off,
^switch off at the wall socket and
withdraw the plug,
^clean the appliance out and
^leave the door ajar to air the
appliance.
If, during a long absence, the
appliance is switched off but not
cleaned out and the door is left shut,
there is a danger of mould and
odours building up inside the
appliance.
Switching on and off
13

It is very important to set the correct
temperature for storing food in the
appliance. Micro-organisms will cause
food which is not stored at the correct
temperature to deteriorate rapidly.
Temperature influences the growth rate
of these micro-organisms. Reducing
the temperature reduces their growth
rate.
The temperature in the appliance will
rise:
–the more often the door is opened
and the longer it is kept open,
– the more food that is stored in it,
– the warmer the food is which is being
put into it,
– the higher the ambient temperature
surrounding the appliance.
The appliance is designed for use in
specific ambient temperatures
(climate ranges). Do not use in
ambient temperatures for which it is
not designed.
...intherefrigerator
We recommend a temperature of 5°C
in the middle of the refrigerator.
Setting the temperature
^Press the temperature button
repeatedly until the indicator light for
the temperature you want lights up in
the display.
The first time you press the button the
indicator light for the last temperature
you set will flash in the display.
The temperature value will change up
until the setting for 9 °C is reached. It
will then drop back to the 1 °C setting.
Temperature display
The temperature display on the
control panel always shows the
required temperature.
The temperature can be adjusted from:
1°Cto9°C
The correct temperature
14

Super cool
The Super cool function can be used to
rapidly reduce the temperature in the
refrigerator section to its lowest setting
(depending on the room temperature).
Switching on Super cool
Super cool is particularly
recommended for faster chilling of
large amounts of fresh food or drink.
^Press the Super cool button. The
Super cool indicator light will come
on.
The appliance will then work at full
power to lower the temperature.
Switching off Super cool
The Super cool function will switch itself
off automatically after approx. 6 hours.
The indicator light will go out and the
appliance will run at normal power
again.
To save energy, the Super cool function
can be switched off once food and
drinks are sufficiently chilled.
^Press the Super cool button. The
Super cool indicator light will go out,
and the appliance will continue to
operate at normal power.
Dynamic cooling m
When the Dynamic cooling function is
not switched on, the natural circulation
of air in the appliance will cause
different temperature zones in the
refrigerator as the cold, heavy air will
sink to the lowest section of the
appliance. You should bear this in mind
when placing food in the appliance
(see "Using the refrigerator efficiently").
However, if you are placing a large
amount of food in the refrigerator at any
one time, it is a good idea to switch on
Dynamic cooling. This way you can
distribute the temperature inside the
appliance to all areas more evenly so
that all the food will be chilled to about
the same degree.
The temperature is set as normal with
the temperature control.
Dynamic cooling should also be
selected when:
– the ambient temperature in the room
is high (above approx. 30 °C), and
–the room humidity level is high.
Switching on Dynamic cooling
^Press the Dynamic cooling button
m. The Dynamic cooling indicator
light will come on.

Switching off Dynamic cooling
^Press the Dynamic cooling button
m. The Dynamic cooling indicator
light will go out.
The fan automatically switches off
when the door is open.
Super cool and Dynamic cooling
16

Different storage zones
Due to the natural circulation of the air
in the appliance, there are different
temperature zones in the refrigerator.
Cold, heavy air sinks to the lowest
section of the appliance. Make use of
the different zones when placing food
in the appliance.
This appliance has Dynamic
cooling, which helps to keep an
even temperature when the fan is
running. When Dynamic cooling is
switched on, the difference between
the various zones is less
pronounced.
Warmest area
The warmest area is in the top section
of the door. Use this for storing butter
and cheese.
Coldest area
The coldest area in a refrigerator is
directly above the vegetable
containers.
Use this for all delicate and highly
perishable food, e.g.
–fish, meat, poultry,
–sausage products, ready meals,
–dishes or baked goods containing
eggs or cream,
–fresh dough, cake mixtures, pizza or
quiche dough,
–soft cheese and other dairy
products,
–pre-packed vegetables and other
fresh food with a label stating it
should be kept at a temperature of
approx. 4 °C.
Do not store explosive materials in
the appliance or any products
containing propellants (e.g. spray
cans). Danger of explosion.
If storing alcohol with a high
percentage proof, make sure it is
tightly closed, and store upright.
Do not store cooking oil in the
refrigerator door. Traces of oil can
cause stress cracks to occur in the
plastic components in the door.
Food must not touch the back wall of
the refrigerator, as it may freeze to
the back wall.
To allow air to circulate efficiently,
do not pack food too closely
together in the refrigerator. Do not
cover the fan in the rear wall of the
refrigerator, as this is essential for
keeping the appliance cool.
Using the refrigerator efficiently
17

Food which should not be
stored in a refrigerator
Not all food is suitable for refrigeration,
as some food is sensitive to cold.
Cucumbers, for example, become
glassy, aubergines bitter and potatoes
sweet. Tomatoes and oranges lose their
aroma, and the peel on citrus fruit
hardens.
Food which should not be stored in a
refrigerator includes:
–pineapple, pomegranate, bananas,
avocado, mangos, papaya, passion
fruit, citrus fruit
– fruit which is not yet ripe
– aubergines/egg plant, cucumbers,
potatoes, peppers/capsicum,
tomatoes, courgettes,
– some hard cheeses, e.g. Parmesan
When shopping for food
The freshness of food when first placed
in the appliance is an important factor
in determining how long it stays fresh,
and how long it can be kept in the
refrigerator. Time out of the refrigerator,
e.g. during transportation, should be
kept to a minimum. For example, do not
allow food to stay in a hot car for too
long. Once food has started to
deteriorate, this process cannot be
reversed. As little as two hours outside
the refrigerator can cause food to start
deteriorating.
Storing food correctly
Food should generally be stored
covered or packaged. This will prevent
food smells from affecting other foods,
food from drying out, and also any
cross-contamination of bacteria. The
growth of bacteria, such as salmonella,
can be avoided by setting the correct
temperature and maintaining good
standards of hygiene.
Fruit and vegetables
Fruit and vegetables may be stored
loose in the vegetable containers.
Please be aware that not all types of
fruit and vegetables are suitable for
storing in the same container. Aromas
and flavours can transfer from one type
of food to another (e.g. carrots absorb
the smell and flavour of onions very
easily). Some food also gives off a
natural gas (ethylene) which speeds up
the rate at which other food perishes.
– Examples of fruit and vegetables
which produce a large amount of
this natural gas are:
Apples, apricots, pears, nectarines,
peaches, plums, avocado, figs,
blueberries, melons and beans.
Using the refrigerator efficiently
18

–Examples of fruit and vegetables
which react strongly to the natural
gases given off by other types of
fruit and vegetables are:
Kiwis, broccoli, cauliflower, brussels
sprouts, mangos, honeydew melons,
apples, apricots, cucumbers,
tomatoes, pears, nectarines and
peaches.
Example: Broccoli should not be
stored with apples, as apples
produce a large amount of natural
gas to which broccoli is very
sensitive. The result is a shorter than
expected storage time for the
broccoli.
Unpacked meat and vegetables
Unpackaged meat and vegetables
should be stored separately. To avoid
any microbiological cross-
contamination, these foods may only be
stored together if they are wrapped.
Protein rich foods
Please note that foods rich in protein
deteriorate faster than others.
Shellfish, for example, deteriorates
faster than fish, and fish deteriorates
faster than meat.
Meat
Meat should be stored unwrapped.
(Undo wrappings slightly to leave meat
loosely covered, and leave containers
open). This permits air to circulate
around the meat, allowing the surface
to dry slightly, which helps prevent the
growth of bacteria. To prevent the risk
of bacterial cross-contamination and
meat deteriorating, do not let one type
of meat come into direct contact with
another type.
Using the refrigerator efficiently
19

Moving the shelves
The shelves can be adjusted according
to the height of the food.
^Raise the shelf, and pull it forwards
slightly until the notch at the side is in
line with the shelf support. It can then
be raised or lowered to the required
level.
The raised edge at the back must face
upwards to prevent food from touching
the back of the appliance and freezing
to it.
Stoppers prevent the shelves from
being dislodged by mistake.
Split shelf
In order to accommodate tall items in
the appliance, one of the shelves is
divided. The front section can be
pushed under the rear section.
^Push the rear half of the glass shelf
up slightly from below.
^At the same time, pull the front half of
the glass shelf forwards slightly and
then push it carefully under the rear
half.
To move the split shelf:
^Take both halves of the split glass
shelf out,
^fit the two brackets onto the supports
on either side at the required height,
^and push the glass shelves in one
after the other.
The shelf with the raised edge must
be at the back.
Adjusting the door shelf/bottle
shelf
^Push the door/bottle shelf upwards,
then remove it by pulling it forwards.
^Replace the door/bottle shelf at the
required position. Ensure that it is
securely pushed back into position.
Moving the bottle divider
(depending on model)
The bottle divider can be moved to the
left or right to ensure that bottles are
held securely in position when the door
is opened and shut.
The bottle divider can be removed
completely (e.g. for cleaning).
^To do this, push up the front edge of
the bottle divider, and disengage it.
