• Ice level check with probe
• Condensing temperature check with probe (machine stop
with temperature > 70°C water version; > of 80°C air).
• maintenance check. the maintenance alert can be pro-
grammed after a certain number of hours of functioning.

• Condenser probe: with condenser temperature < 24°C, the
board makes the fan turn guaranteeing optimal condition of
condensation and machine yield.

• on the starting the machine goes into defrosting and dis-
charge the water pan.
• the production cycle start with two minutes of delay that
allow a correct balancing of the refrigeration system and
therefore a good output and a best production.
• During the machine operation, at the end of every defrost-
ing, the water load happens with 80 seconds of delay, this to
allow the evaporator subcooling.
• when the bin is full of ice, the probe comes in contact with
the ice and the electronic card stop the machine only on the
end of defrosting time. this to always have the cubes com-
pletely formed and at the same dimensions.
• Signalling of alarms for the models air and water version:
- condenser overheating : the machine goes to alarm and it
restart again automatically once that the cause has been re-
moved and / or the temperature has re-entered in the range
of established operation;
- error of not water feeding: in case of lack of water the ma-
chine automatically start again after 60 minutes from the
alarm reset.
