THE FOLLOWING OPERATIONS SHOULD BE PERFORMED EXCLUSIVELY BY QUALIFIED AND AU-
THORISED PERSONNEL.

IN CASE OF INCORRECT OPERATION, IT IS RECOMMENDED TO DISCONNECT THE MACHINE FROM
THE ELECTRICAL AND HYDRAULIC SUPPLY NETWORK.
Alarm
(AL01) Alarm: cold cycle
too long
(AL02) Alarm: cold cy-
cles duration difference
(AL03) Alarm: no water
(if sensor present)
(AL04) Alarm: ice bin
probe faulty
(AL05) Routine mainte-
nance request
(AL06) High temperature
at condenser outlet
(AL07) Condenser probe
alarm
(AL08) Evaporator probe
(if present)
(AL09) Blackout - No
power supply
Machine status
Machine stops in standby; a simple
press of the button restarts the machine.
Machine continues to work; reset alarm
by pressing button
Machine stopped or waiting for an auto-
matic start-up attempt
Machine stopped
Machine continues to work
Machine stops, condenser fan remains
on to lower the condenser temperature,
or water valve remains open in case of
water condensation. (once it has cooled
down, the machine restarts making a
few attempts to see if the alarm is no
longer present, then it stops permanent-
ly)
Condenser probe faulty or outside
allowed value range, the machine works
with continuous ventilation or water inlet
always activated.
Evaporator probe faulty or outside
allowed value range, the machine works
with historical data if necessary
The machine will resume operation in
the state before the power failure.

Decrease cube size, check cleanliness and
ventilation of condenser, check for gas leaks,
check position of evaporator probe.
If the machine started hot, or the size of
the cubes was changed, check for alarms
after 3 continuous cycles, check cleanliness
and ventilation of condenser, check water
temperature if stable, check for gas leaks,
check position and insulation of evaporator
Check water supply, check for water leaks in
the circuit, check operation of water inlet valve
Check probe-board connection, check
probe integrity, check that the ohm value
read is correct, replace probe - By checking
beforehand that there is space in the bin, two
ice production cycles can be started by pressing
Call technical assistance for periodic
maintenance (reset the message by pressing
the button for 10 seconds)
Check cleanliness and ventilation of condenser,
check that the condenser fan is turning, check
position of condenser probe; in water-cooled
versions, check the water supply and operation
Check condenser probe-board connection,
check that the ohm value read is correct,
Check evaporator probe-board connection,
check for ice cube accumulation in the
evaporator area, check that the ohm value read
Check the electrical connections and power
source. (To remove the alarm message, press
once to silence the buzzer, press again to
remove the message if within the first minute,
second press only if the minute has already
