6

Warning and Safety instructions

 Danger of suffocation! Whilst playing, children could become en-

tangled in packaging (such as plastic wrapping) or pull it over their
head and suffocate. Keep packaging material away from children.

Technical safety

 The coolant system is tested for leaks. The wine conditioning unit

complies with statutory safety requirements and the appropriate EU
guidelines.

 This wine conditioning unit 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, and does not have any adverse effect
on the performance of the appliance.
Care must be taken during the transportation and setting up of the
wine conditioning unit that no parts of the cooling system are dam­aged. Leaking coolant can damage the eyes.
In the event of any damage:

– avoid naked flames or anything which creates a spark,
– disconnect the appliance from the mains electricity supply,
– ventilate the room where the wine conditioning unit is located for

several minutes, and

– contact the Miele Service Department.

7

Warning and Safety instructions

 The more coolant there is in a wine conditioning unit, 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 11 g of coolant at least 1m3 of room space is
required. The amount of coolant in the appliance is stated on the
data plate inside the wine conditioning unit.

 To avoid the risk of damage to the wine conditioning unit, 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 wine conditioning
unit. Consult a qualified electrician if in any doubt.

 The electrical safety of the wine conditioning unit 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.

 Reliable and safe operation of the wine conditioning unit can only

be assured if it has been connected to the mains electricity supply.

 If the electrical connection cable is faulty it must only be replaced

by a Miele authorised service technician to protect the user from
danger.

 Do not connect the wine conditioning unit 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, it could cause a short

circuit. Therefore, do not operate this wine conditioning unit in areas
which are exposed to moisture (e.g in a garage or utility room).

8

Warning and Safety instructions

 This wine conditioning unit must not be used in a non-stationary

location (e.g. on a ship).

 Do not use a damaged wine conditioning unit. It could be danger-

ous. Check the wine conditioning unit for visible signs of damage.

 For safety reasons, this wine conditioning unit may only be used

after it has been built in.

 The wine conditioning unit must be isolated from the electricity

supply during installation, maintenance and repair work.

 Unauthorised installation, maintenance and repairs can cause

considerable danger for the user.
Installation, maintenance and repairs must only be carried out by a
Miele authorised technician.

 While the wine conditioning unit is under warranty, repairs should

only be undertaken by a Miele authorised service technician. Other­wise the warranty is invalidated.

 Miele can only guarantee the safety of the appliance when genu-

ine original Miele replacement parts are used. Faulty components
must only be replaced by Miele spare parts.

Correct use

 The wine conditioning unit is designed for use within a certain cli-

mate range (ambient temperatures), and should not be used outside
this range. The climate range for your wine conditioning unit 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 wine con­ditioning unit switching off for longer periods so that it cannot main­tain the required temperature.

 Do not cover or block the air vents as this could impair the effi-

ciency of the appliance, increase the electricity consumption and
could cause damage to the components.

9

Warning and Safety instructions

 If the wine conditioning unit is used for storing food which con-

tains fat or oil, make sure that it does not come into contact with
plastic components as any spillages of oil or fat could cause stress
cracks to the plastic and cause it to break or split.

 Do not store explosive materials in the wine conditioning unit or

any products containing propellants (e.g. spray cans). Electrical
components could cause flammable vapours to ignite. Danger of fire
and explosion.

 Do not operate any electrical equipment inside the wine condition-

ing unit. Danger of sparking and explosion.

 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.

10

Warning and Safety instructions

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.

 Do not use a steam cleaning appliance to clean this wine condi-

tioning unit.
The steam could reach electrical components and cause a short cir­cuit.

 Sharp edged or pointed objects will damage the evaporator, caus-

ing irreversible damage to the wine conditioning unit. Do not use
sharp edged or pointed objects to

– remove frost and ice,
– remove labels, stickers etc.

11

Warning and Safety instructions

Transporting the appliance

 Always transport the wine conditioning unit in an upright position

and in its original transport packaging to avoid damage in transit.

 Danger of injury and damage. The wine conditioning unit is very

heavy and must be transported by two people.

Disposing 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.

 Splashes of coolant can damage the eyes. Be careful not to dam-

age 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. In normal operation there is no risk.

 The oil in the compressor can be fatal if swallowed or if it penet-

rates the airways.

12

Caring for the environment

Disposal of the packing mater­ial

The packaging is designed to protect
the wine conditioning unit 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.

Disposal 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.

Take care not to damage the pipework
at the back of your wine conditioning
unit before or during transportation to
an authorised collection depot.
In this way, coolant in the pipework and
oil in the compressor will be contained,
and will not leak into the environment.

Please ensure that your old appliance
presents no danger to children while
being stored awaiting disposal. See
"Warning and Safety instructions" for
more information.

The optimum temperature and air quality

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 on
the air quality.

The wine conditioning unit with its con­stant ideal temperature, increased air
humidity and odour free atmosphere of­fers the perfect conditions for storing
your wine.

It also guarantees a vibration-free envir­onment (in contrast to a refrigerator) so
that the maturing process is not dis­turbed.

The optimum temperature

Wine can be stored at a temperature
between 6 and 18 °C. If you are storing
white and red wines together, select a
temperature between 12 and 14 °C.
This is suitable for both white and red
wines. Red wine should be taken out of
the wine conditioning unit and opened
at least two hours before drinking to al­low it to breathe and develop its aroma.

At too high a temperature (over 22°C)
wine matures too quickly, which pre­vents the aromas from developing fur­ther. Wine cannot mature fully at too
low a temperature (below 5°C).

Fluctuations in temperature put wine
under stress and interrupt the maturing
process. It is therefore very important to
maintain a constant temperature.

Type of wine Recommended
