).
).
a
Note: Install the machine in a position that the ventilation of the
ooling unit is not obstructed in any way (only for air-cooled ma-
c
chines) (fig.
• Do not install the machine in a dusty room as the condenser of
the cooling unit can be easily clogged (only for air-cooled machines) (fig. 2)).
If the machine is installed in an area where the drinking water
•
has a high content of salt solutions, follow the manufacturer's
instructions in order to minimise the problem.
• To prevent the ice from absorbing bad smells and tastes, never
store food, bottles, etc. in the container.
• Do not leave the ice container door open during normal operation.
There must be a differential switch (cut-out) in the electrical system.
1.1. CONNECTING THE APPLIANCE TO THE MAINS
• If the power supply cable is damaged, it must be replaced
by qualified personnel to prevent any hazards to persons
s
).
Connect only to the drinking water mains
5. Use the new set of mobile junctions (water pipe) supplied
with the appliance. The old set of junctions must not be
reused.
6. Install the water connections before the electrical connections.
7. Connect the 3/4’’ supply pipe (supplied) to the machine and
to the cold drinking water supply line.
For practical and safety purposes, it is advisable to install a
shut-off valve (not supplied by us) (fig. h: 1. switch; 2. socket;
3. electrical plug; 4. water supply; 5. valve; 6. water drain from
the condenser: water-cooled version; 7. water drain from the

71503928/0 - REV.00 01/2013
2. ACTIVATING THE MACHINE 3. OPERATION
iii
Implement the following operations before activating the
ice maker.
. look at the pictures:
1
• remove the cover by loosening the relative fastening screws.
• release the gear motor, the blades and the float (where applicable) by removing the factory-set stops 1, 2 and 3, which
have been fixed to prevent damage during transport (fig.
. For the water-cooled models connect also the second
)
j
fitting to the water outlet, which conveys the water coming
from the condenser.
Note: Implement a minimum inclination of 3% to the pipes for
perfect water flow from the appliance, ensuring that these have
no narrowing sections and are not siphoned. It is advisable that
the pipes drain into an open siphon (fig.
2. Connect the machine to the power supply after having verified that the mains voltage corresponds to that on the serial
number plate on the rear panel of the appliance.
The maximum voltage variation tolerance allowed is ±
10% of the rated value.
• Provide a power supply circuit to the machine, with its own
bipolar main switch and a minimum of 3 mm contact opening. The machine should also have its own fuse or automatic
protection and an earthed plug.
• All must be sized according to the amperage indicated on
the serial number plate (fig. ;). The socket must be easily
accessible.
h
).
Simply press the ON/OFF button to start and stop the
machine.
• The ice cube makers can be easily adapted to the furnishing
of every room.
• The ice cubes are formed around the fingers of the evaporator, inside a tray filled with water and continuously moved
y revolving blades.
b
• The level of the water in the tray is kept constant by a float
connected to a microswitch that controls the opening and
closing of a water inlet electrovalve of the water supply.
• When the ice cubes reach the required dimensions, they
come in contact with the revolving blades that cause the relative gear motor to swing, which stresses a micro switch and
simultaneously causes the following through a relay:
- the delivery of hot gas to the evaporator by an electrovalve
opening, which leads to the cubes gradually dropping off
the fingers of the evaporator.
- the tilting of the water tray connected by means of a lever
to a gear motor.
• The cubes drop and slide on a slanting grid inside the tray
and are conveyed into the container beneath.
• The remaining water in the tray is collected into the relative
pan on one side of the container and conveyed towards the
drain. The tray automatically returns to its horizontal position
after about a minute and fills with water till the pre-set level.
In the meantime, the hot gas valve closes and the ice forming cycle proceeds smoothly; a complete cycle can vary from
about 15’ to about 25’ depending on the water and room
temperatures.
• The quantity of ice inside the container is controlled by the
electronic sensor fixed on one side of the container itself;
when the ice cubes reach the level of the bulb, the machine
stops completely. After removing enough ice from the container for no cubes to be in contact with the bulb, the appliance will resume its normal production.
English
Note: After removing the ice cubes, remove any remaining ice
on the control bulb for production to resume quicker.
3.1 ALARM SIGNALS FOR AIR / WATER MODELS
• Overheating condenser: the machine restarts automatically
once the alarm has been resolved. The cause may be due to:
clogged air filter, faulty fan, room temperature too high, no
water (only in the water version).
• Water error: if there is no water, the machine restarts automatically 60 minutes after the alarm is triggered.
Note: You can exit from the alarm status after having disconnected / connected the power supply (ON/OFF button).
• The machine stops when the container is full: the sensor
of the container is controlled by the control board and stops
the machine when the ice comes in contact with it. The machine stops at the end of the defrosting cycle.

OPERATING PROBLEMS
• If the condenser overheats
The machine stops and only the air/water condensation remains in operation. The machine automatically restarts when the temperature returns to below the limits set. Only after three consecutive alarms within a period of 5 hours, the machine turns off and
stays off.
• Freezing cycle too long
In the case of three consecutive alarms within 5 hours, the machine stops.
Calculation of the maximum time of the freezing cycle:
1stcycle = 50'
2ndcycle = duration of 1 cycle x 1.5.
If the 1st cycle lasted less than 7' the maximum time of the next cycle will be 50'.
• Defrosting too long
If the defrosting time is greater than 2 minutes and there are 2 consecutive failures within 5 hours, the machine stops.
• Freezing cycle less than 7 minutes
The electronics calculate the cycle time as too long at 50 minutes.
• Water loading too long
If the load time for the water is greater than 5' the machine stops in alarm. After a break of 120' the machine restarts automatically.
If water shortage is ongoing, the machine will attempt to restart every 120'.

8.3 OPERATION CHARACTERISTICS
• On the starting the machine goes into defrosting and disharge the water pan.
c
• 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-
ng, the water load happens with 80 seconds of delay, this to
i
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 completely 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 removed 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 machine automatically start again after 60 minutes from the
alarm reset.
• Condenser probe: with condenser temperature < 24°C, the
board makes the fan turn guaranteeing optimal condition of
condensation and machine yield.
