Caring for the environment
Disposal of the packing
material
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.
The transport and protective packing
has been selected from materials which
are environmentally friendly for
disposal, and should 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!
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.
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.

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 m3 of
room space is required. The amount of
coolant in the appliance is stated on the

The correct temperature
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 first time you press the button the
indicator light for the last temperature
you set will flash in the display.
– the warmer the food is which is being
put into it,
– the higher the ambient temperature
surrounding the appliance.
The temperature value will change up
until the setting for 9 °C is reached. It
will then drop back to the 1 °C setting.
The appliance is designed for use in
specific ambient temperatures
(climate ranges). Do not use in
ambient temperatures for which it is
not designed.
The newly selected temperature will be
adopted automatically after a short
while.
The indicator for the temperature which

Using the refrigerator efficiently
Different storage zones
should be kept at a temperature of
approx. 4 °C.
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.
Do not store explosive materials in
the appliance or any products
containing propellants (e.g. spray
cans). Danger of explosion.
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 less pronounced.
If storing alcohol with a high
percentage proof, make sure it is
tightly closed, and store upright.
Please be aware if storing cooking
oil in the appliance that traces of oil
can cause stress cracks to occur in
plastic components.
Warmest area
The warmest area is in the top section
of the door. Use this for storing butter
and cheese.
Food must not touch the back wall of
the appliance, as it may freeze to
the back wall.
Coldest area
The coldest area in a refrigerator is
directly above the vegetable containers
and at 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.
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

Using the refrigerator efficiently
Food which is not suitable for
storing in the refrigerator
Storing food correctly
Store food covered or packaged. This
will prevent food smells from affecting
other food, 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.
Not all food is suitable for storing in a
refrigerator at temperatures below 5 °C,
as some food does not tolerate cold
temperatures. Cucumbers, for example,
become glassy, aubergines bitter and
potatoes sweet. Tomatoes and oranges
loose their aroma, and the peel on
citrus fruits hardens.
Fruit and vegetables
Food which does not tolerate cold
temperatures includes:
Fruit and vegetables may be stored
loose in the vegetable containers.
However, please bear in mind that not
all types of fruit and vegetables are
suitable for storing in the same
– Pineapple, avocado, bananas,
pomegranate, mango, melon,
papaya, passion fruit,
citrus fruit (such as lemons, oranges,
mandarins, grapefruit),
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. Some fruit
and vegetables react strongly to this
gas and should not be stored together.
– Fruit which is not yet ripe,
– Aubergines/egg plant, cucumber,
potatoes, peppers/capiscum,
tomatoes, courgettes/zucchini,
– Some hard cheeses, e.g. Parmesan.
When shopping for food
Examples of fruit and vegetables
which produce a large amount of this
natural gas are:
The freshness of food when first placed
in the appliance is an important factor in
determining how long it stays fresh.
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.
Apples, apricots, pears, nectarines,
peaches, plums, avocados, figs,
blueberries, melons and beans.

Using the refrigerator efficiently
Examples of fruit and vegetables
which react strongly to the natural
gases given off by other types of fruit
and vegetables are:
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.
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.

Automatic defrost
The refrigerator defrosts automatically.
Condensate and frost can build up on
the back wall of the refrigerator whilst it
is in use. You do not need to remove
this, as it will defrost and evaporate
automatically with the warmth
generated by the appliance.
The condensate is drained away via a
channel and drain hole into an
evaporation system at the back of the
appliance.

and drain hole are kept clean and
are never blocked so that
condensate can flow away without
hindrance.

depth 580 mm) the appliance can be
installed directly next to a kitchen
furniture housing unit. The appliance
door will protrude in front of furniture
fronts at the sides by 34 mm and by
55 mm in the middle of the door. This
enables the doors to be opened and
shut without being obstructed.
When installed next to a wall d a
distance of approx. 55 mm must be
maintained on the hinge side between
the wall d and the appliance b, so
that the doors and the handles have
sufficient space for opening.
