- 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 every 8 g of coolant at least 1 m3of
room space is required. The amount of
coolant in the appliance is stated on the
data plate inside the appliance.
Before connecting the appliance to
the mains supply, make sure that
the rating on the data plate
corresponds to the voltage and
frequency of the household supply.
This data must correspond in order to
avoid the risk of damage to the
appliance. If in any doubt, consult a
qualified electrician.

Wine keeps on maturing depending on
the surrounding conditions. The length
of time for which wine can be kept in
good condition will therefore depend
not only on the temperature but also the
air quality.
Temperature
Wine can be stored at a temperature
between 5°C and 18°C. The optimum
temperature is around 10-12°C. Most
white wines can be consumed at this
temperature. It is best to take red wine
out of the wine cooler about two hours
before drinking. Open the wine to allow
it to breathe and to develop its aroma.
After two hours, red wine will be at the
correct temperature for drinking.
If wine is stored at a temperature above
22°C it will mature too quickly. Wine
should not be stored below 5°C for a
long period of time as it will not mature
fully at this low temperature.
Fluctuations in temperature put wine
under stress and interrupt the maturing
process. It is therefore very important to
maintain a constant temperature.
Safety features
A thermostat prevents the temperature
in the wine cooler falling too low.
Internal heating automatically switches
on to keep the temperature inside as
constant as possible.
Isolation shelf for thermal separation
The appliance has a fixed isolation
shelf which divides the cabinet into two
zones. The temperature for each zone
can be set separately so that different
wines (red and white) can be stored at
their ideal temperature.
Setting the temperature
The temperatures are set using the two
buttons under the temperature
displays.
Press the
left hand button: to raise the
temperature (it gets warmer)
right hand button: to reduce the
temperature (it gets colder)
The temperature being set will flash in
the display.
When pressing the buttons, the
following information shows in the
display:
–When first pressed, the last
temperature selected flashes.
–Each subsequent press of the button
adjusts the temperature shown in
1 °C steps.
–Keeping the button pressed in
adjusts the temperature continually.
The correct temperature and humidity
12

Approx. 5 seconds after letting go of
the button, the current temperature
inside the applicable zone is
automatically shown.
The two temperature zones are cooled
alternately, which means that
depending on the quantity of wine
being stored, it can take several hours
for the required temperature to be
reached, and for the temperature
display to adjust. If, after this time, the
temperature is still too high or too low,
you will need to adjust it again.
Temperature range
The temperature can be adjusted from
5°C to 18°C.
Temperature display
During normal operation, the
temperature displays on the control
panel show the temperatures inside the
appliance.
The temperature display will flash if
–a different temperature is being set,
–the temperature in one of the zones
deviates by more than 5 °C from the
set temperature.
Temperature display brightness
The appliance is supplied with the
brightness of the temperature display
set as low as possible.
You can adjust the brightness of the
temperature display (both temperature
displays will be adjusted together):
^Press and hold the constant humidity
button in for approx. 5 seconds.
The constant humidity indicator light will
flash, and a ;will flash in the right hand
temperature display.
^Press one of the left hand
temperature selector buttons for the
upper zone repeatedly until an
^appears in the display.
^Press the constant humidity button
again.
^lights up in the display.
^You can now adjust the level of
brightness by pressing the
temperature selector buttons for the
upper zone. You can choose from
settings 1to 5:
1: lowest setting,
5: brightest setting.
The correct temperature and humidity
13

^Press the constant humidity button to
save the setting.
^Press the On/Off button to come out
of the setting mode. If you do not do
this the electronics will switch over to
normal operation automatically after a
couple of minutes.
Humidity level
It is very important to store wine in an
atmosphere with a high humidity level
(60-70 %) so that the corks remain
moist on the outside. A refrigerator with
its low humidity level is therefore not the
best place to store wine. At a low
humidity level corks dry out from the
outside, and so do not seal the bottles
tightly. Wine should be stored lying
down to keep the corks moist from the
inside too. Air entering the bottle will
inevitably spoil the wine.
Useful tip:Before serving, stand the
wine upright for at least two hours, or
the entire day if possible, to allow
any sediment to settle at the bottom
of the bottle.
Constant humidity (Dynamic cooling)
button m
This setting enables the relative
humidity inside the wine cooler and the
temperature to be distributed evenly
around the interior so you can store all
your wine under the exactly the same
excellent conditions.
Switching on
If you would like to use the wine cooler
to store wine long term, the constant
humidity setting should be activated.
This will create a continuous climate in
the cabinet which imitates that of a wine
cellar.
^Press the constant humidity button
m. The indicator light will come on.
Even if this setting has not been
activated, the fan in the appliance
will come on automatically when the
cooling system switches on to
ensure your wine is kept in the
optimum climate.
The fan automatically switches off
when the door is open.
The correct temperature and humidity
14

Switching off
Because the appliance uses more
energy when this setting is switched on,
it should not be left switched on all the
time.
^To switch it off, press the constant
humidity button m. The indicator
light will go out.
Air filtering with the active charcoal
filter
The active charcoal filters maintain the
air quality in the wine cooler by filtering
the incoming air to ensure that all air
entering the appliance is fresh and free
from dust and smells.
Replace the active charcoal filters
with new ones once a year (see
"Cleaning and care"). These are
available from your dealer or the
Miele Spare Parts Department.
The correct temperature and humidity
15

There is lighting in both the upper and
lower zones of the wine cooler so that
both zones can be lit up.
Do not remove the lamp covers.
Should the covers be damaged or
need to be removed due to damage,
exercise caution. There are lasers
in the lighting (laser beam class 1M)
which you should avoid looking at
directly.
Switching on the interior lighting
Wine should generally be stored in the
dark. However, the interior lighting can
be switched on to enable you to see the
wine stored in the wine cooler.
^Press the interior lighting button.
Both lights are switched on or off
simultaneously.
Adjusting the brightness
The brightness of the interior lighting
can be adjusted.
^Press and hold the interior lighting
button.
^At the same time, press the right
hand temperature selector buttons
for the lower zone.
Press the
left hand button: to dim the lighting
right hand button: to make the lighting
brighter

Any vibration or movement of the bottle
can affect the wine by interrupting the
natural respiration process and so
impair the taste.
As far as possible store bottles of the
same type of wine beside each other
on the same shelf. Removing a bottle of
one type will then leave the other types
undisturbed and will avoid the need to
move different bottles around.
Capacity
Approx. 40 Bordeaux bottles (0.75 l)
17 in the upper zone
23 in the lower zone
Wooden shelves
The wooden shelves are on runners
and can be pulled out to make it easier
to store and remove bottles.
Descriptive labels
Use the labels supplied to identify your
wine quickly and easily. Insert the
labels into the metal holders at the front
of the shelves from above.
Additional labels can be purchased
from your Miele dealer or from the
Spare Parts Department.

Your appliance is fitted with a warning
system which ensures that the
temperature cannot rise or fall
unnoticed and impair the wine.
Temperature alarm
An alarm will sound if the temperature
in one of the zones rises or falls outside
the temperature range. The relevant
temperature display will flash at the
same time.
The temperature the appliance is set at
determines the temperature the
appliance recognises as being too
warm or too cool.
The alarm will sound and the
temperature display will flash:
– when you switch the appliance on, if
the temperature inside the appliance
is very different from the temperature
set.
– when there has been a lengthy
interruption to the power supply.
Door alarm
If the door has been left open for more
than approx. 60 seconds the alarm will
sound.
Activating the alarm system
The alarm system is always active. It
does not have to be switched on
manually.
Switching the alarm off early
Once the set temperature has been
reached in the appliance, the alarm
stops and the relevant temperature
display lights up constantly. However, if
the noise disturbs you, you can switch
the alarm off before this if you wish.
^Press the alarm "off" button.
The alarm will stop. The relevant
temperature display continues to
flash until the set temperature has
been reached. The display then
lights up constantly, and the alarm
system is fully active again.

Condensate and frost can build up on
the back wall of the appliance whilst it
is in use. These are automatically
removed and defrosted by the
appliance.
The condensate is drained away via a
channel and drain hole into an
evaporation system at the back of the
appliance.
Ensure that the condensate channel
and drain hole are never blocked so
that condensate can flow away
without hindrance.
Defrosting
19

Never use cleaning agents
containing abrasive substances
such as sand, soda, acids or
chemical solvents.
"Non-abrasive" cleaning agents are
also unsuitable as they can cause
matt areas to appear.
Make sure that water cannot get into
the electronic unit or into the lighting.
Do not let water get into the
drainage channel and drain hole
when cleaning.
Do not use steam cleaning
apparatus to clean the appliance.
Steam could reach the electrical
components and cause a short
circuit.
The data plate located inside the
appliance must not be removed. It
contains information which is
required in the event of a Service
call.
Before cleaning
^Switch the appliance off at the wall
socket and remove the plug.
^Take out any removable parts, e.g.
shelves, for cleaning.
Cleaning the interior, the door
and accessories
Use warm water with a little washing up
liquid. Accessories and shelves should
all be hand-washed only.
^Clean the condensate channel and
drain hole frequently, so that
condensate can drain away
unhindered. Use a straw or similar to
clear the drain if necessary.
^After cleaning, wipe the interior and
accessories with a damp cloth and
dry with a soft cloth. Leave the door
open to air the appliance for a short
while.
^Clean the appliance door with a
proprietary glass cleaner.
E-Cloth
A microfibre "E-Cloth" is available from
the Miele UK Spare Parts Department,
which is suitable for cleaning surfaces
such as stainless steel, glass, plastic
and chrome without the use of
chemicals.
Ventilation gaps
^The ventilation gaps should be
cleaned regularly with a brush or
vacuum cleaner. A build-up of dust
will increase the energy consumption
of the appliance.
