1Clean and sanitize the unit according to the
instructions in this manual. See chapter 7.3
CLEANING AND SANITIZING PROCEDURES.
2Fill the bowls with product to the maximum
level mark. Do not overfill.
The exact quantity of product (expressed as
liters and gallons) is shown by marks on the
bowl.
3In case of products to be diluted with water,
potable water, pour water into bowl first, then add
correct quantity of product. In case of natural
squashes, it is advisable to strain them, in order
to prevent pulps from obstructing the faucet
outlet.
4To obtain the best performance and result,
use bases designed to be run in Granita
IMPORTANT
When handling the machine never grasp it
by the bowls or by the evaporator
cylinders. The manufacturer refuses all
responsibilities for possible damages
which may occur through incorrect
handling.
ATTENTION
Failure to provide proper electrical ground

freezers. Such bases have a sugar content of 34
degrees Baumé corresponding to 64 degrees
Brix.
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.
5Set the control switches as shown in chapter
7.1 DESCRIPTION OF CONTROLS.
6Always leave the dispenser on, as the
refrigeration stops automatically when Granita
reaches the proper thickness. The mixers will
continue to turn.
7. 1 DESCRIPTION OF CONTROLS
The dispenser is equipped with a power 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 7.2 OPERATION HELPFUL
HINTS).
ETC VERSION
All the switches are located on the faucet side of
the dispenser.
Dispenser controls functions are as follows (see
figure 1).

function is useful during machine rinsing, washing
and sanitising to prevent the contents of the unit
from being cooled. It is nonetheless always
possible to quit cleaning mode simply by pressing
any key.
Temperature adjustment in DRINK mode: the
optimal temperature of drinks (when the
dispenser works as a drinks cooler rather than as
an ice crusher) is factory set to 4°C. If you want to
adjust the temperature, hold down keys (C) and
(D) simultaneously for two seconds. The indicator
light (E) and the temperature set will flash and you
can adjust it using keys (C) and (D). The display
will go blank for a few seconds and then the
current temperature will be displayed.
Minimum temperature adjustment in
GRANITA mode: you can also adjust the
minimum temperature of the product when the
dispenser is operating in granita mode. This
minimum temperature is factory set to -10°C. If
you want to adjust it, hold down keys (C) and (D)
simultaneously for two seconds to go into drink
temperature adjustment mode and the indicator
light (E) will flash. Press keys (C) and (D) for two
seconds to go into granita minimum temperature

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).
figure 4
2The 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.
3To shorten Granita recovery time and
increase productivity, it is advisable to pre-chill
the product to be used in the dispenser.
4To 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.
5For 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.
6Mixers 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.
7The dispenser is equipped with a magnetic
coupling by which the gear motor (located
outside the bowl) drives the mixers (inside the
bowl).
The magnetic drive operates as an “intelligent
clutch” able to automatically disconnect the
mixers in case they are seized by ice or other
causes.
This inconvenience can be soon noticed since an
intermittent dull noise warns that mixers are still.
In this case it is necessary to unplug immediately
the dispenser, empty the bowl and eliminate the
cause of seizing.
8The dispenser must be able to emit heat.
In case it seems excessive, check that no
heating source is close to the unit and air flow
through the slotted panels is not obstructed by
wall or boxes. Allow at least 15 cm (6”) of free
clearance all around the dispenser.
In any case if the product in the bowls is frozen
and the pressure switch warning light is OFF the
unit is running properly.
9The product is for use with confectionery
only.
7. 3 CLEANING AND SANITIZING
PROCEDURES
1Cleaning and sanitizing of the dispenser are
recommended to guarantee the conservation of
the best product taste and the highest unit
efficiency. This section is a procedural guideline
