Periodical cleaning of the condenser
In order to optimize the operation of the
appliance and save energy, it is
recommended to periodically clean the dust
from the condenser unit at the back of the
appliance.
Disconnect the appliance from the power mains
before you start cleaning it!
x Empty the contents of the appliance.
x Remove the support panel from the bottom of
the kitchen cabinet.
x Remove the screws fixing the appliance to the
kitchen worktop.
x Pull out the appliance to expose the condenser
at the back of the appliance.
x Unscrew the screws from the condenser bonnet
and remove the bonnet.
x Clean the dust and dirt from the condenser.
After cleaning return the appliance to its place,
plug in the power cord and fill with food.

longer period of time, disconnect the power supply,

Troubleshooting guide
During service, you may come across some
problems that result in most cases from improper
handling of the appliance and which can easy be
eliminated.
The appliance fails to operate after connecting
to the power mains
x Check the voltage in the socket and see if the
appliance is switched on (green signal lamp is
on).
Sound alarm, red signal lamp is on
If the temperature in the freezer is too high, this is
signalled by the red signal lamp and the acoustic
alarm which may be switched off by pressing the
alarm off button (3). When the lamp goes off the
interior of the freezer has again reached the
appropriate temperature.
Another increase of temperature within the freezer
is again signalled both by the red lamp and the
sound alarm.
The reasons for this may be the following:
x The door was frequently opened or it was left
opened for too long.
x The door is not properly closed (the door may
sag; the gasket may be polluted or damaged).
x Power supply has been interrupted for a longer
period of time.
x Perhaps you have overloaded the appliance with
fresh food.
Acoustic alarm activated, red lamp is off
Excessive layer of dust on the condenser unit or
around the air circulation openings in the bottom
rail may activate the sound alarm. It may be
switched off by pressing the alarm off button (3).
Clean the condenser unit and the air circulation
openings in the bottom rail (consult the section
Cleaning of the appliance).
Cooling system is operating continuously
x Continuous operation mode is on (yellow lamp is
on).
x Press the button (2) and switch off the
continuous operation mode (yellow lamp goes
off).
x Insufficient cooling of compressor and
condenser. This is signalled by the sound alarm.
Check the air circulation through the bottom rail
openings and clean or vacuum the dust from the
condenser unit if necessary. See section
Cleaning and maintenance.
