11 - OZONATOR

This function is only available when the machine is
stopped and is activated by pressing the ozonation
button (12) (the LED of the button comes on) . The ozone
is released for 120 minutes after which the release ends
(the LED goes off ). At the same time as the Ozonator the
fan is also activated to facilitate movement.
During the sterilisation cycle the word "Ozone" will
flash on the display (18) and the display (19) will show
the countdown of the cycle time. If the door is opened
during the 120 minutes, the sterilisation cycle will stop
IMMEDIATELY; it will not even start upon closing of the
door, and the scrolling text "STOP Ozone Cycle" will appear
for 5 seconds. If the ozonator is not installed the scrolling
text "Ozone Not Present - Ozone non presente" will appear
on the display for 10 seconds.

12 - ICE-CREAM CYCLE

This cycle enables the user to use the chiller in negative
chiller mode with a Timer that schedules the introduction
and extraction of ice-cream containers, allowing the
surfaces to harden, after leaving the ice-cream making
machine.
With the machine in stop mode, press the "ice-cream"
button (10); the beeper will emit a beep and the LED of
the button will start to flash. The negative chilling cycle
will start immediately (to cool the machine), the display
(19) of the time will show the flashing cycle time while
the display (18) will indecate the tempetature of the cell
probe.
The user has the option,n at this point, to modify the time
of the hardening cycle by pressing the "+" and "-", and to
confirm the time by pressing the "ice-cream" button (10).
After this setting when the user opens the door (to
introduce the ice-cream) and then reclose it, a beep is
emitted as comfirmation and the countdown will start.
When the time reaches zero, the beeper will sound for
60 seconds, and the sliding text "carica gelato - charge
ice cream" will appear. Then whenever the door is closed,
any countdown in progress is interrupted and a new one
starts.
During the cycle the user may at any time change the time
and the temperature set as default as follows:
1) by pressing the "ice-cream" button (10), with the first
time press the time on the display (19) will flash and it can
be changed with the +/- buttons.
2) the next press of the button (10) will acquire the new
value.
3) now using the buttons +/- it is possible to chance the
Part Number: 9294045 07/19
flashing set represented on the display (18) with a value
that can range from the minimum value to a maximum
one (this theoretically allows setting of the long softening
cycles for ice-cream which, extracted from the storage
machine, must be placed on display.)
4) pressing the button (10) allows saving of the new value
followed by the return to the cycle.
The user can stop this cycle at ay time by pressing the
START/STOP button (22).

13 - THAWING CYCLE

This function aims to safely thaw (below 50°F (10°C)
of temperature cell) previously frozen or deep-frozen
products. The process is based both on cell temperature
control, with a positive value between 38°F (3°C) and 50°F
(10°C) average, and on the action of forced ventilation.
When the machine is stopped, select the thawing cycle by
pressing the button (15); the cycle will start immediately
showing on the "display 19" the standard thawing time
and on "display 18" the measured cell temperature.
To change the values of time and temperature set, simply
press the button (15) until the display flashes which
will present the time value set. With the +/- buttons it is
possible to modify the thawing time. With the modification
completed with the +/- buttons it is possible to change
the SET which will be confirmed by pressing the button (5)
or by waiting 5 seconds.
The the temperature set value flashes on the display (8)
which can also be changed with the +/- buttons. With
the modification completed with the +/- buttons (6) it is
possible to change the SET by pressing the button (3) or
by waiting 5 seconds.
Then on the display, if VE2 is different from 100, the
wording "HARD FANS" will be represented (if fan
regulation is enabled). To confirm press the button (5),
while to change press the +/- buttons until appearance
of the second option "SOFT FANS" (reduced evaporator
fan speed); pressing the button (5) the value selected is
confirmed.
After this operation, the cycle in fuction is resumed which
when finished will activate the beeper and the scrolling
text "End Cycle - Fine Ciclo" will appear. At that time the
cycle will go into storage.
To see the value of the insert probe during thawing, simply
press the button (12) which will display the product probe
value for 5 seconds flashing on the display (18) and the
wording "SP1" and "SP2" is shown on the display (19) to
distinguish the probe reading.
