• there is no power cut, and the switch (6 in Fig. 3) is in the "ON" position, and the luminous switch (21 in Fig. 2) is lit (250 kg/24h
output model only)
• none of the safety devices described in chapter 8 has operated
Furthermore:
• if there is excessive noise, make sure that the appliance is not touching furniture or sheet metal which can give rise to noise or
vibrations
• should any trace of water appear, check the drain hole of the bin to ensure that it is not clogged, that the water fill and drain
pipes are correctly connected and are not throttled or damaged
• make sure that the temperature of the air or water does not exceed the installation limit values (see paragraph 5.2)
• make sure that the water inlet filter is not clogged (see paragraph 9.1)
• check that the holes in the spray ring are not obstructed by limescale
If the fault still persists after the above checks have been made, switch off the appliance with the switch fitted during the
installation stage, turn off the water supply tap(s), and contact the nearest Authorized Service Centre.
To obtain a faster and more efficient reply when you call the Centre, state the model of the appliance precisely, together with its
serial number or manufacturing number. This information is given on the serial N° plate (Fig. 1) affixed to the rear of the appliance
and on the cover of this instruction manual.

8 OPERATION

The appliance is fitted with the following safety devices:
• all models are fitted with a safety microswitch which shuts down the appliance if ice enters the evaporator chamber. The
appliance automatically restarts when the evaporator chamber is clear of excess ice
• models with a daily output of 250 kg, 400 kg, 620 kg, 900 kg and 1500 kg are fitted with a safety thermostat which shuts down
the appliance when the ice which has accumulated in the bin reaches the probe connected to the thermostat. When ice is
removed from the bin, the appliance is automatically reactivated
• all models are fitted with a safety maximum pressure switch which shuts down production in the event of a malfunction of the
cooling circuit such as start-up in an excessively warm environment, fan malfunction or dirty finned condenser (air-cooled
models), lack of water to condenser or water-operated condenser obstructed (water-cooled models), etc. If the appliance shuts
down when the bin is not full of ice, to check the operation of the protective devices wait for 3 minutes and firmly press the reset
button (if any) located on the left wall of the appliance. If the fault persists, the appliance will shut down again; in this case,
disconnect the appliance from the mains power supply, close the water supply tap(s), and contact the nearest Authorized
Service Centre
• all models are fitted with a safety minimum pressure switch which operates in the event of a malfunction such as shutdown of
scraper, lack of ice-making water, etc. If the appliance shuts down when the bin is not full of ice, to check the operation of the
protective devices wait for 3 minutes and firmly press the reset button (if any) located on the left wall of the appliance. If the fault
persists, the appliance will shut down again; in this case, disconnect the appliance from the mains power supply, close the water
supply tap(s), and contact the nearest Authorized Service Centre
IMPORTANT: DO NOT USE the safety microswitch to control the level of ice accumulated in the bin; install a
dedicated device for that purpose.
The device can be one of two types:
• a level control installed in the bin (photocell, etc.) which shuts down the appliance when the established level is
reached and reactivates the ice-cube maker when ice is removed from the bin
• a timer that switches the appliance on and off according to ice consumption and the capacity of the bin

NOTE FOR INSTALLER:
This operation must only be performed by qualified, authorized personnel.
The model with daily output of 2200 kg is fitted with a device which controls the sequence of the electrical power phases; if the
appliance fails to operate once connected to the mains power supply, and none of the protective devices described so far has
operated, disconnect the appliance from the mains power supply and invert two of the three phases.
If the appliance does not resume normal service after this operation, disconnect the appliance from the mains power supply, turn
off the water supply tap(s) and contact the nearest Authorized Service Centre.
