For soft drinks the bases are to be diluted with more water,
on a 1 plus 5/5.5 basis.
In any case follow the syrup manufacturer’s instructions for
both Granita and soft drink recipes.
If natural juices (e.g. lemon, orange) as well as sugarless
products (e.g. coffee) are used, dissolve 150 - 200 grams
of sugar per liter.
5 - Install the covers and check that they are correctly placed
over the bowls. There must be a correct electrical connec-
tion between the bowl and the cover.

- Set the control switches as shown in chapter
5.1 DESCRIPTION OF CONTROLS.
7 - Always leave the dispenser on, as the refrigeration stops
automatically when Granita reaches the proper thickness.
The mixers will continue to turn.
5. 1 DESCRIPTION OF CONTROLS
The dispenser is equipped with a power switch and a light
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 1).
figure 1
In addition the dispenser is equipped with automatic safety
pressure switches to prevent damages to the compressors.
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 3 dispenser controls functions are as
follows:

Power switch (A)
Light switch (E)
Mixer/refrigeration switch (B)
Thermostat (D)
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 3):
- toward right (clockwise) to obtain a thicker product (the
indicator F will go down in opening G).
- toward left (counterclockwise) to obtain a thinner product
IMPORTANT
However Granita mix may be done, its Brix (sugar
percent content) must be at least 13.
