Drink/Night mode and the opposite. This means that during
defrost periods frozen Granita will melt to thermostat setting
temperature and once defrost period has expired, the product
automatically freezes down again to Granita setting viscosity.
The Defrost Timer is equipped with a four digit display, some si-
gnal dots and three keys whose functions are the following:
A Confirmation key
B Increase key
C Decrease key
D Seconds dots
E Granita/Day Mode dot
F PM dot
G Drink/Night Mode dot
H Defrost Timer ON/OFF dot
To operate the Defrost Timer proceed as follows:
1 SET THE TIME OF THE DAY
Press keys A and B simultaneously to enter the Current
Time Setting Mode. Press keys B and C to set the
individual values and press key A to confirm and move on
to the next selection. The following values must be set:
a.European or American Time Mode: the value "24" or
"12" will flash on the display.
b.Setting of current hour: the first two digits will flash on
the display.
c.Setting of current minutes: the second two digits will
flash on the display.
Once finished the current time will be shown on the
display and the two dots (D) will flash.
If American Time Mode is selected dot F will be on during
post meridiem hours.
2 PROGRAM THE DEFROST TIMER
Press keys A and C simultaneously to enter the Defrost
Intervals Setting Mode. The setting will always start from
time 00:00 and Granita/Day Mode indicated by dot E.
Press keys B and C to increase or decrease the time by
intervals of 15 minutes and press key A to modify the
operating mode from Granita/Day, indicated by dot E, to
Soft Drink/Night, indicated by dot G, and vice versa.
To adjust the intervals, you must select whether the ma-
chine should be in Granita/Day or Drink/Night mode at
time 00:00 by pressing key A and then press key B until
you reach the time you want to change the operating mo-
de. Now press key A again to switch the mode and the
dots E or G will come on to indicate the selected mode. It
is possible to scroll backwards and forwards using keys
B and C to check the defrost time intervals. It is possible
to commute the operating mode every 15 minutes. In or-
der to exit the Defrost Intervals Setting Mode it is neces-
sary to set time 23:45 (11:45 PM), press key B and
message "end" will be shown on the display and then
press key A to confirm the exit.
3 TIMER ON/OFF
Once finished the programming, the Defrost Timer is still
deactivated and "----" is shown on the display. Press key
A for 3 seconds to activate the Defrost Timer and vice
versa. Dot H will indicate the state of the timer.
Note: when the Defrost Timer is deactivated the defrost
function is OFF (the machine operates as if it were not
equipped with Defrost Timer).
8 OPERATION HELPFUL HINTS
1 Granita viscosity adjustment: proper Granita viscosity is
factory preset. To change the viscosity, if needed, use a
standard screwdriver to turn the adjustment screw located in
the rear wall of each container as follows (see figure 4):
- towards right (clockwise) to obtain a thicker product (the
indicator F will go down in opening G).
- towards left (counterclockwise) to obtain a thinner product
(the indicator F will go up in opening G).
2 Beverage temperature adjustment: proper beverage
temperature is factory preset. To reset, turn the knob located in
each switch box as follows:
- towards right (clockwise) to decrease temperature.
- towards left (counterclockwise) to increase temperature.

thermostat only when the mixer/refrigeration switch(es)
are in I position, Soft Drink mode.
3 The length of time for freeze down of Granita is governed by
many variables, such as ambient temperature, mix initial
temperature, sugar content (Brix level) and viscosity setting.
4 To shorten Granita recovery time and increase productivity,
it is advisable to pre-chill the product to be used in the
dispenser.
5 To shorten Granita recovery time and increase productivity,
the bowl should be refilled after the product level drops lower
than half of the evaporator cylinder and at the start of each day.
6 For good product conservation the dispenser must run
overnight, at least in Soft Drink mode.
If this is not possible and product is left in the bowls overnight,
the mixer/refrigeration switches must be set to the I position at
least one hour before the unit is switched off. This eliminates
any block of iced product forming overnight, which could result
in damage to mixers or to their motor when the unit is switched
back on. In any case, before the unit is restarted, make sure
that no blocks of ice have been formed; if so, they are to be
