take appropriate action.
Setting up
• Avoid positioning the appliance in direct sunlight or near cookers,
radiators and similar sources of heat.
• The floor on which the appliance stands should be horizontal
and level.
• Standard EN 378 specifies that the room in which you install
your appliance must have a volume of 1 m3 per 8 g of R 290a
refrigerant used in the appliance, so as to avoid the formation of
inflammable gas/air mixtures in the room where the appliance is
located in the event of a leak in the refrigerant circuit.The quantity
of refrigerant used in your appliance is indicated on the type plate
on the inside of the appliance.
• There must be a gap of at least 30 cm
between the upper edge of the appliance
and the ceiling.

• a long power failure;
• a fault in the appliance.
If a large quantity of warm items is placed in the appliance at once,
this alarm may occur. This does not mean that there is an error.
Call up the length of the temperature rise and the maximum temperature reached inside the appliance. See chapter "Calling up

Cleaning
Clean the appliance at least twice per year.
Before cleaning always switch off the appliance. Pull out
the mains plug or switch off or unscrew the fuse.
• Empty the appliance and store the food in a cool place.
• Clean the inside and equipment with lukewarm water and a little detergent. Do not use abrasive or acid cleaners or chemical
solvents.
Do not use steam cleaners because of the
risk of injury and damage.
• Ensure that no cleaning water penetrates into the electrical
components or ventilation grille.
• Dry all parts well with a cloth.
• Use a commercially available stainless-steel cleaning agent for
stainless-steel appliances.
Do not use abrasive sponges or scourers, do not use concentrated cleaning agents and never use cleaning agents
containing sand, chloride or acid or chemical solvents, as
these would damage the surfaces and could cause corrosion.
Cleaning the dust filter
Clean the dust filter at least twice
per year!
EN
Malfunctions
You may be able to rectify the following faults by checking
the possible causes yourself:
• Appliance does not function:
–Is the appliance switched on?
–Is the plug correctly fitted in the mains socket?
–Is the fuse intact?
• The temperature is not low enough:
–Is the temperature setting correct (see "Setting the temperature")?
– Does the separately installed thermometer show the correct
reading?
– Is the ventilation system working properly?
– Is the appliance set up too close to a heat source?
If none of the above causes
apply and you cannot rectify
the fault yourself, contact the
nearest customer service department stating the type designation  , service number 
and appliance number 
as
indicated on the type plate.

1.Open door by about 90°.
Important note
The door must be opened 90°
before the lower hinge bracket
is removed.
This will hold the self-closing
mechanism that is integrated into
the door in the required position for
installation.
Plastic washer
Note on point 4
The hinge bushing with brass washer and bearing ring may stick in the door mounting when
you pull out the hinge bracket and, in this case,
must be removed from it.
WARNING!
If the door is removed and reinstalled in the
closed position, this will lead to destruction of
the self-closing mechanism on the first opening of the door.
Important
As a result of its heavy weight, the door
must be held secure by one person.
2.Remove hinge bracket.
Pull the door out at the
bottom and lift off.
5.Transfer the upper hinge bracket and covers to the
opposite side.
6.Turn the door by 180°.
