Electrical connection
Switching the appliance on and off
Only operate the appliance with alternating current (AC).
Connect the appliance to the mains - the display reads OFF.
The permissible voltage and frequency are indicated on the type
plate. The position of the type plate is shown in the section entitled
Description of the appliance.
The socket must be properly earthed and protected by a fuse.
The tripping current of the fuse must be between 10 A and 16 A.
Switching the appliance on: Keep the ON/OFF button
pressed for approx. 5 seconds - the display reads ON.
No alarm is displayed or sounded when the appliance is switched
on for the first time.
Iftheapplianceisdisconnectedfromthemainsforalongtimeafter
it has been switched on for the first time and if the temperature
inside the appliance rises above the upper alarm limit, this will
be detected as a fault by the electronic control system (HACCP
appears in the display).
The socket must not be situated behind the appli-
ance and must be easily accessible.
Do not connect the appliance using an exten-
sion cable or extension socket.
When the appliance is switched on again, this display must be
reset as shown below.
Do not use stand-alone inverters (conversion
ofdirectcurrenttoalternating/three-phasecur-
rent) or energy-saving plugs. Risk of damage
to the electronic control system!

Defrosting
The grid shelves can be moved
to accommodate different height
bottles or packages.
The appliance defrosts automatically. The water that forms on the
rear wall drains into a reservoir at the back of the appliance and

The ventilation slots of the
recirculating fan on the inside

• Ensure that no cleaning water penetrates into the electrical com-
ponents or ventilation grille.
• The dust should be removed from the refrigeration unit and heat
exchanger - metal grid at the back of the appliance - once a year.
• Do not damage or remove the type plate on the inside of the ap-
pliance. It is very important for servicing purposes.
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?
2. Pull out strain relief device (bot-
tom left of interior container).
• Loud running noise:
– Is the appliance set up firmly on the floor?
– Does the appliance cause nearby items of furniture or objects to
vibrate? Please note that noises caused by the refrigerant circuit
cannot be avoided.
• The temperature is not low enough:
