switch. In addition each bowl is individually operated by a mixer/
refrigeration switch. In fact it is possible to dispense both soft
drinks and Granita.
When a bowl is in Soft Drink mode the beverage temperature is
controlled by the corresponding thermostat.
When a bowl is in Granita mode the mix viscosity is controlled
by the corresponding adjustment screw located in the rear wall
of each container (for temperature and viscosity setting make
reference to chapter 5.2 OPERATION HELPFUL HINTS).
All the switches are located on the faucet side of the dispenser
in switch panels protected by switch covers (see figure 4).

In addition all the models are equipped with an automatic safety
pressure switch to prevent damages to the compressor. The
lighting of the warning light at the left of the switch covers means
insufficient ventilation of the unit. In this case check that all
around the dispenser there is sufficient space for ventilation, at
least 15 cm (6") on each side and that condenser filter is free
from dust or other obstructions.
In case the warning light is still ON even after these operations
have been carried out, Service call is required.
With reference to figure 5 dispenser controls functions are as
follows:
figure 5
Power switch (A)
0 position : power is turned OFF to all functions.
I position : power is turned ON to all functions and the
other switches are enabled. The fan motor
runs.
Light switch (E)
0 position : all top cover lights are OFF.
I position : all top cover lights are ON, provided that
power switch (A) is set to I.
Mixer/refrigeration switch (B)
I position : mixer and refrigeration ON.
SOFT DRINK mode.
0 position : OFF.
II position : mixer and refrigeration ON.
GRANITA mode.
Thermostat (D)
Turn clockwise
Turn counterclockwise
To operate the unit:
1 Set the power switch to I position.
2 Set the mixer/refrigeration switches as follows:
- to the I position to get soft drink.
- to the II position to get Granita.
3 Set the light switch to I position.
5. 2 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 6):
- 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
removed before the unit is switched on. Overnight operation in
drink mode also eliminates possible ice accumulation from
condensation all around the bowls.
7 Mixers must not be turned off when frozen product is in the
bowl: if not agitated, the product may freeze to a solid block of
ice. If the mixers are turned back on in this situation, damage to
the mixers and their motor may result. Therefore, mixers may
be restarted only after product is melted.
