PERIODICAL MAINTENANCE
We suggest to carry out a thorough cleaning of the counter once a month for the
good working, the good preservation of the food and the aesthetics preservation
of the equipment. The periodical cleaning can be made by qualified people, who
should know the procedure described in this paragraph. ATTENTION! Before
starting any cleaning operation it is necessary to turn off the equipment by the
on / off red switch (see picture I) and to unplug or disconnect the equipment by
the general power security switch of your shop. Important - DURING THE WOLE
CLEANING OPERATION USE WORKING GLOVES OF CLASS II TO PROTECT
YOUR HANDALL THE TIME.
To carry out the cleaning it is necessary :
1 - to remove all goods from the refrigerated unit and to keep them in a freedge or
in a refrigerated ambient suitable for their preservation;
2 - to unplug or disconnect the main on / off switch, disconnect the plug from the
power socket and wait until the equipment temperature reaches the room tem-
perature;
3 - carefully and thoroughly clean the display surface, the refrigerated storage, the
glasses, the aluminium profile, the door gasket with specific cleaners for any sur-
face. Never use abrasive substances, metal pads or other stuff which can damage
the unit.
4 - After every cleaning operation it is necessary to rinse with warm water and dry
the unit with a soft cloth;
5 - to clean the condenser too, use a dry paint brush and /or a vacuum cleaner,
removing all dust. Pay attention not to bend or damage the fins, the tubes or the
blades of the fans. When the cleaning operation is over, make sure that everything
is clean and dry before connecting the equipment to the power supply again.When
the unit reaches the correct working temperature, it is possible to reload it. In case
of long absences (i.e. holidays etc.) the unit has to be unplugged, emptied completely,
cleaned and dried. Make sure to leave
the doors open to prevent bad smells.
DEFROSTING
The defrosting takes place automatical-
ly during the running of the unit. The
defrosting cycles are 4 a day, last for
about 40' each and are controlled by
a timer in the electrical control panel.
During the defrosting phase the tempe-
rature of the unit could be altered, but
when this cycle is over, in a short time
the working temperature will return to
normal. The water from defrost is col-
lected in a remouvable drip tray which
should be emptied when necessary.

ELECTRONIC THERMOSTAT
TEMPERATURE MODIFICATION
• Press for 5 seconds to display the selected parameter value;
press or to reach the required temperature;
• Press to confirm.
INDICATION ON THE DISPLAY
There are three LEDs of button back-lightening which display the operating status
of the instrument, available only for TOP versions. For cheap versions, only one seg-
ment of the display signals compressor ON.
• Button Led indicates compressor ON
• Button Led indicates defrosting ON
• Button Led indicates presence of alarms.
The blinking status means that the corresponding function is delayed by a timed
routine.A particular blinking of the
Continuous Cycle is delayed by the compressor timed routines.
ALARMS AND SIGNALS
BLINKED functioning LED
• If a LED blinks it means that the corresponding function is delayed by a timed
routine, by another procedure or inhibited by the digital input.
E0 BLINKS faulty regulation probe:
• Used probe is not compatible with the control;
• The probe cable is interrupted or short circuited;
• Faulty sensor: take out the probe from the control and verify the resistance (NTC:
25°C=10KΩ).
E1 BLINKS faulty evaporator probe or food probe:
• Used probe is not compatible with the control;
• The probe cable is interrupted or short circuited;

• Faulty sensor: take out the probe from the control and verify the resistance (NTC:
25°C=10KΩ).
IA BLINKS immediate external alarm:
• Check the "Mutifunction" input and the A4 and A7 parameters.
LO BLINKS low temperature alarm (temperature less than SET -AL):
• Verify the AL,Ad and A0 parameters;
• The alarm disappears as soon as the temperature rises and ranges within the
selected limits.
HI BLINKS high temperature alarm (temperature higher than SET+AH):
• Verify the AH,AD and A0 parameters;
• The alarm disappears as soon as the temperature decreases and ranges within the
selected limits.
EE data acquisition failure, controller RESET:
Set again the default parameters value, to restore correct operation. Re-setting
the default values causes the loss of the modifications relative to the working
c
parameters.
• switch-OFF the control;
• Press the and buttons while switching on the control; "-CF" is displayed;
• After a few seconds the instrument enters the RESET phase and starts to work.
Ed BLINKS timeout defrost:
• Verify the dt, dP and d4 parameters;
• Verify defrost efficient.
dF BLINKS defrost currently ON:
• It is not an alarm signal. It simply indicates a defrost cycle in progress. It appears
only if the parameter d6=0.
TEMPERATURE
The thermostat, which is situated on the electrical control panel, regulates the
temperature into the equipment and is usually preset to +0 / + 6 C° at the factory
during the testing phase.
A lower performance must be expected from the refrigerated unit when:
- the equipment is set on the lowest temperature
- the equipment is positioned in an ambient with higher temperature or relative
humidity than above indicated
- the amount of displayed goods exceeds the maximum recommended and the
proper air circulation is prevented.
In those cases the goods are kept at higher temperatures, the refrigerating unit has
to run non - stop and ice may form on the evaporator. It is necessary therefore to
turn the equipment off (approx. 24 hours) to allow the melting of the ice.
TECHNICAL ASSISTENCE (servicing)
If the equipment does not run properly or does not work at all, in your own inte-
rest before calling for servicing, we suggest to check the following points:
- if the plug is well inserted in the socket;
- if the power reachs the socket to which the equipment is connected;
- if the thermostat is set as recommended;
- if the doors are perfectly closed;
- if the network voltage is the same as requested for the unit (+/- 6%).
DISMANTELLING OF EQUIPMENT
The demolition of the unit and the recovery of the component materials must be
carried out according to the regulation in force in this matter. Considering that the
equipment is formed by many different materials (i.e ABS with polyurethane foam
for isolation, glass, stainless steel , aluminium, copper etc.) and some of them are like
normal urban waste materials while other components, as refrigeration gas and oil,
MUST be given to a special recycling center.
REPLACEMENT OF LAMPS
The replacement and the substitution of lamps must be made by qualified technician
and when the unit is disconnected from the power net. Disconnect the main power
supply before fitting or replacing the lamp. Slip the ring nuts onto the fluorescent
lamp. Fit the lamp in the lampholder and turn it 90°. Slide the ring nuts along the lamp
until they rest on the lampholder and turn them clockwise (NPP and NPQ); screw
down tightly (NPW).
