8. TECHNICAL SERVICE DATA

THE FOLLOWING OPERATIONS MUST BE
IMPLEMENTED SOLELY BY OUR
QUALIFIED PERSONNEL

8.1 ELECTRONIC BOARD FUNCTIONS

• 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.
• wash/cleaning cycle check to be carried out periodically with
manual control.

• Condenser probe: with condenser temperature < 24°C, the
board makes the fan turn guaranteeing optimal condition of
condensation and machine yield.
• resistance values of the temperature probes (deposit probe
and condenser probe) with reference to the room tempera-
ture:

8.3 OPERATION CHARACTERISTICS

• 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.

8.4 WASHING CYCLE

i
Note:
• time of complete washing cycle: 3 hours
• the washing / cleaning cycle is formed of: 90 minutes of
washing plus 5 rinsing of 15 minutes each.
• at the end of the washing cycle the machine automatically
start again in cold cycle.
• the water level sensor inside the basin works with waters
with conductivity between 20 and 1000 micro-siemens per
centimetre.
• the water level sensor can be replaced by a micro oat. Con-
nection is the same for both.
• If the machine is supplied with softened water (deminer-
alised), oat kit installation is recommended ( g.
In case of incorrect startup cycle (by the user) to exit the
cycle you must press the reset button for more than 10 se-
conds during the wash. (Not active during rinse cycle).
