Blown protective fuse
First find the cause of the trip
of the switch, and then replace the new fuse.
The master switch is open
Close the master switch.
The plug is not inserted
Insert the plug.
Electrical black-out
If the black-out should be prolonged, transfer the product into
an appropriate cold storage container.
THE TEMPERATURE
IS NOT SUFFICIENTLY
LOW
Evaporator(s) completely blocked
with ice
Carry out an additional defrosting cycle.
Wrong temperature setting
Set the appropriate temperature.
Equipment being struck by
currents of air or exposed to
direct or reflected sunlight
Remove any draughts and prevent any direct or reflected
sunlight.
Insufficient air flow for
cooling to the condenser
Remove anything which could obstruct
the circulation of air through the condenser (sheets of paper,
cardboard, insufficient slots in grille, etc.).
THE COMPRESSOR
DOES NOT START
WORKING OR WORKS FOR
VERY SHORT PERIODS
No electric power supply
to the appliance
Check if there is a power cut.
Close the various switches on the power supply line.
Excessively low power voltage
Check that the mains voltage of the power
supply cable corresponds to the nominal value 220V +/- 10%.
Temperature set too high
If the temperature is higher than the air temperature
in the display chamber, the compressor will not start.
Set the suited temperature if the current temperature
is not low enough.
If the appliance is not working properly or stops working, before contacting the

SOLUTION
THE TEMPERATURE
IS NOT SUFFICIENTLY
LOW
Internal ventilators
not working
or damaged fans
Replace the ventilators/fans.
Thermostat /
Electronic control board
not efficient
Replace the thermostat/electronic control board.
If the electronic control board is used on appliances with R290
coolant, it must only be replaced with an original spare part
supplied by the manufacturer. Replace the temperature probes
only after having ascertained which of them
is inefficient.
Condensing unit blocked
with dust or dirt
in general
Clean the condensing unit thoroughly.
The condensing unit in particular operating environments
(e.g. presence of dust, presence of excessive humidity, etc.)
when the performance of the appliance deteriorates requires
careful cleaning.
Insufficient refrigerant
load in the
cooling system
Find the cause of the refrigerant loss and remove it;
top up the refrigerant load if necessary having emptied
the system.
THE COMPRESSOR
DOES NOT START WORK-
ING OR WORKS FOR
VERY SHORT PERIODS
Maximum pressure
switch triggered
(if present)
Check the reasons why the pressure switch is operating at
maximum pressure levels, such as: air condenser obstructed,
condenser fan with air stopped, ambient
temperature too high, pressure switch defective.
