Technical safety
 The coolant circuit has been checked for leaks. The refrigeration
appliance complies with statutory safety requirements and the
appropriate EU directives.
 This refrigeration appliance contains the coolant Isobutane
(R600a), a natural gas which is environmentally friendly. The coolant
does not damage the ozone layer and does not contribute to 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 cooling circuit. Unfortunately, this cannot be avoided, but it does
not affect the performance of the refrigeration appliance.
When transporting and installing the refrigeration appliance, ensure
that no parts of the cooling circuit are damaged. Splashes of coolant
can damage the eyes.
In the event of damage:
- Avoid naked flames or anything which creates a spark.
- Disconnect the refrigeration appliance from the mains electricity
supply.
- Ventilate the room where the refrigeration appliance is located for
several minutes.
- Contact your Miele Dealer.
 The more coolant there is in a refrigeration 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 a combustible
gas/air mixture building up. For every 8g of coolant at least 1m3 of
room space is required. The amount of coolant in the refrigeration
appliance is stated on the data plate inside the appliance.

Warning and Safety instructions
9
 To avoid the risk of damage to the appliance, make sure that the
connection data (fuse rating, frequency and voltage) on the data
plate corresponds to the household supply.
Check that this is the case before connecting the appliance. Consult
a qualified electrician if in any doubt.
 The electrical safety of this appliance can only be guaranteed
when correctly earthed. It is essential that this standard safety
requirement is met. If in any doubt please have the electrical
installation tested by a qualified electrician.
 Temporary or permanent operation on an autonomous power
supply system or a power supply system that is not synchronised
with the mains power supply (e.g. island networks, back-up systems)
is possible. A prerequisite for operation is that the power supply
system complies with the specifications of EN50160 or an
equivalent standard.
The function and operation of the protective measures provided in
the domestic electrical installation and in this Miele product must
also be maintained in isolated operation or in operation that is not
synchronised with the mains power supply, or these measures must
be replaced by equivalent measures in the installation. As described,
for example, in the current version of BS OHSAS 18001–2 ISO
45001.
 If the electrical connection cable supplied is damaged, it must
only be replaced by an original spare part to prevent a hazard for the
user. Miele can only guarantee the safety of the appliance when
original Miele spare parts are used.
 Do not connect the appliance to the mains electrical supply by a
multi-socket adapter or extension lead. These are a fire hazard and
do not guarantee the required safety of the appliance.
 If moisture gets into electrical components or into the mains
connection cable, it could cause a short circuit. Therefore, do not
operate this refrigeration appliance in areas which are exposed to
moisture (e.g in a garage or utility room).

Warning and Safety instructions

 This refrigeration appliance is designed for use within specific
ambient temperatures (climate range). Do not use in ambient
temperatures for which it is not designed. The climate range is stated
on the data plate in the interior cabinet of the refrigeration appliance.
A lower ambient temperature will cause the compressor to switch off
for longer periods, meaning that the refrigeration appliance is unable
to maintain the required temperature.
 Do not cover or block the air vents as this could impair the
efficiency of the appliance, increase the electricity consumption and
could cause damage to the components.
 If storing food which contains a lot of fat or oil in the appliance or
the door, make sure that it does not come into contact with plastic
components as this could cause stress cracks or break the plastic.
 Risk of fire and explosion. Do not store explosive materials in the
refrigeration appliance or any products containing propellants (e.g.
spray cans). Electrical components can cause flammable mixes of
gases to ignite.
 WARNING! Danger of explosion. Do not operate any electrical
equipment (e.g. an electric ice-cream maker) inside the refrigeration
appliance. Danger of sparking and explosion.
 Danger of injury and damage to the appliance. Do not store cans
or bottles containing carbonated drinks or liquids which could freeze
in the freezer zone. Otherwise they could burst.
 Danger of injury and damage to the appliance. When cooling
drinks quickly in the freezer zone, make sure bottles are not left in for
more than one hour. Otherwise they could burst.
 Danger of injury. Never handle frozen food or the metal parts of
the appliance with wet hands. Your hands may freeze to the frozen
food or to the metal.

Warning and Safety instructions
12
 Danger of injury. Do not take ice cubes out with your bare hands
and never place ice cubes or ice lollies in your mouth straight from
the freezer zone. The very low temperature of the frozen food can
cause frost burn to the lips and tongue.
 Do not refreeze partially or fully defrosted food. Consume
defrosted food as soon as possible, as it will lose its nutritional value
and spoil if left for too long. Defrosted food may only be re-frozen
after it has been cooked.
 Observe the manufacturer's “use-by” dates and storage
instructions 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.
Accessories and spare parts
 Only use original Miele accessories. If other parts are used,
warranty, performance and product liability claims will be invalidated.
 Miele will guarantee to supply functional spare parts for a
minimum of 10years and up to 15years following the
discontinuation of your refrigeration appliance.
Cleaning and care
 Do not use any oils or grease on the door seals, as these will
cause the seals to deteriorate and become porous with time.
 WARNING! DANGER of injury and damage! Do not use any
mechanical or other types of aids which are not recommended by
the manufacturer to accelerate the defrosting process.
 Do not use a steam cleaning appliance to clean or defrost this
appliance.
Steam could reach electrical components and cause a short circuit.

Warning and Safety instructions
13
 Sharp edged or pointed objects will damage the evaporator,
causing irreversible damage to the appliance. Do not use sharp
edged or pointed objects to
- remove frost and ice,
- separate frozen food or remove ice trays.
 Do not place electric heaters or candles in the appliance to
defrost it. These can damage the plastic parts.
 Do not use defrosting sprays or de-icers, as they could contain
substances which could damage the plastic parts or which might
cause the build-up of gases and pose a danger to health.
Transport
 Always transport the appliance in an upright position and in its
original transport packaging to avoid damage in transit.
 Danger of injury and damage to the appliance. The refrigeration
appliance is very heavy and must be transported by two people.
Disposal of your old appliance
 Children playing could become trapped in the appliance and
could suffocate.
- Remove the appliance doors.
- Remove the drawers.
- Leave the adjustable shelves in the refrigeration appliance so
children cannot climb inside.
- If your old refrigeration appliance has a door lock, destroy it. This
will prevent the risk of children playing accidentally locking

 Risk of electric shock!
- Cut the power plug off the mains connection cable.
- Cut the mains connection cable off the old appliance.

Warning and Safety instructions
14
 Dispose of everything separately from the old appliance.
 During and after disposal, make sure that the refrigeration
appliance is not placed near petrol or other flammable gases and
liquids.
 Risk of fire due to escaping oil or refrigerant!
The refrigerant and oil inside the appliance are flammable. In high
enough concentrations, escaping refrigerant or oil may ignite if they
come into contact with an external heat source.
During disposal, make sure that the cooling circuit is not damaged in
order to prevent refrigerant and oil escaping in an uncontrolled
manner (see the data plate for details of the refrigerant).
 Splashes of coolant can damage the eyes. Be careful not to
damage any part of the pipework whilst awaiting disposal, e.g. by
- puncturing the coolant channels in the condenser,
- bending any pipework, or
- scratching the surface coating.
Symbol on the compressor (depending on model)
This information is only relevant for recycling. There is no risk during normal
operation.
 The oil in the compressor can be fatal if swallowed or if it
penetrates the airways.

Caring for the environment
15
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
contain many valuable materials. They
also contain certain materials,
compounds and components which
were essential for their correct
functioning and safety. These could be
hazardous to human health and to the
environment if disposed of with
household waste or if handled
incorrectly. Please do not, therefore,
dispose of your old appliance with
household waste.
Instead, please make use of officially
designated collection and disposal
points to dispose of and recycle
electrical and electronic appliances in
your local community, with your Miele
dealer. By law, you are solely
responsible for deleting any personal
data from the old appliance prior to
disposal.
Take care not to damage your
refrigeration appliance’s pipework
before or during transportation to an
authorised collection depot.
This is to ensure that refrigerant in the
cooling circuit and oil in the compressor
is contained, and will not leak into the
environment.
Ensure that your old appliance presents
no danger to children while being
stored for disposal. For further
information, see “Warning and safety
instructions” in these operating
instructions.

Installation
*INSTALLATION*
17
Risk of damage due to high
humidity.
In environments with high humidity,
condensation can build up on
external refrigeration appliance
panels.
This condensate can cause corrosion
on external appliance panels.
Install the refrigeration appliance in a
dry and/or air-conditioned room with
sufficient ventilation.
After installation please make sure
that the appliance door(s) closes
(close) properly and the refrigeration
appliance is installed in accordance
with these installation instructions. It
is essential to comply with the
specified ventilation cutout
requirements.
Side-by-side combinations
Risk of damage due to
condensation on external appliance
panels.
In environments with high humidity,
condensation can build up on
external appliance panels, which can
cause corrosion.
Do not place different refrigeration
appliance models directly next to or
on top of one other.
If the model number for your
refrigeration appliance does have the
letter “S” in it, it can be installed “side-
by-side”. Your refrigeration appliance is
equipped with built-in heating units in
the side panels.
If the model number for your
refrigeration appliance does not have
the letter “S” in it, it cannot be installed
“side-by-side”. Your refrigeration
appliance must not be installed “side-
by-side” because it is not equipped
with built-in heating units in the side
panels.
Exception: your refrigeration appliance
can be installed next to another
refrigeration appliance with an
integrated heating unit if each appliance
is built into a separate niche. Please
contact your dealer for specific
information about which combinations
will work with your refrigeration
appliance.
Climate range
This refrigeration appliance is designed
for use within specific ambient
temperatures (climate range). Do not
use in ambient temperatures for which it
is not designed. The climate range is
stated on the data plate in the interior
cabinet of the refrigeration appliance.
Climate range Ambient
temperature
SN +10to +32°C
N +16to +32°C
ST +16to +38°C
T +16to +43°C
A lower ambient temperature leads to
the compressor switching off for longer
periods. This can cause the internal
temperature in the refrigeration
appliance to rise with the risk of food
deteriorating and going off.

Installation
*INSTALLATION*
18
Ventilation
Risk of fire and damage due to
insufficient ventilation.
If the refrigeration appliance is not
ventilated sufficiently, the
compressor will run more frequently
and for longer periods. This will
result in increased energy
consumption and a higher operating
temperature for the compressor. This
may, in turn, cause damage to the
compressor.
Please ensure that there is adequate
ventilation around the refrigeration
appliance.
It is essential to observe the required
ventilation gaps.
The ventilation gaps must not be
covered or blocked in any way.
They must also be regularly dusted.
Air at the back of the refrigeration
appliance gets warm. The appliance
housing unit must therefore be
constructed to allow sufficient space for
ventilation (see “Installation
dimensions” and the installation
instructions provided).
Furniture door panel
Horizontal and vertical gaps
Depending on the style of kitchen
furniture, the thickness and edge radius
of the furniture door panel and the gap
that runs around the door, vertically and
horizontally, are specified.
It is essential to pay attention to the
following:
-Horizontal gap
The gap between the furniture door
panel and the housing unit door above
or below it must be at least 3mm.
-Vertical gap
If the gap between the refrigeration
appliance furniture door panel and
the adjoining housing unit door or
wall on the hinged side is too small,
the appliance door could collide with
the adjoining housing unit door or
wall when opened.
It may be necessary to adjust the
size of this gap to suit the thickness
and edge radius of the appliance
furniture door.
This must be taken into consideration
when planning your kitchen and when
replacing an old refrigeration appliance
with a new one to ensure the installation
conditions required are met.
