2 INTRODUCTION
Please read all sections of this manual thoroughly to familiarize
yourself with all aspects of the unit.
Like all mechanical products, this machine will require cleaning
and maintenance. Besides, dispenser working can be
compromised by operator’s mistakes during disassembly and
cleaning. It is strongly recommended that personnel
responsible for the equipment’s daily operations, disassembly,
cleaning, sanitizing and assembly, go through these
procedures in order to be properly trained and to make sure
that no misunderstandings exist.
3 INSTALLATION

and keep them for possible future use.
2 - Inspect the uncrated unit for any possible damage. If
damage is found, call the delivering carrier immed iately to
file a claim.
3 - Install the unit on a counter top that will support the
combined weight of dispenser and product bearing in
mind what is stated in the preceding point 1
IMPORTANT warning.
4 - A minimum of 15 cm (6”) of free air space all around the
unit should be allowed to guarantee adequate ventilation.
5 - Ensure that the legs are screwed tightly into the base of
the machine.
Replace the standard legs originally installed with the 100
mm (4”) legs whenever they are provided with the unit.
6 - Before plugging the unit in, check if the voltage is the same
as that indicated on the data plate. Plug the unit into a
grounded, protected single phase electrical supply
according to the applicable electrical codes and the
specifications of your machine. When the unit has no plug,
install a proper grounded plug, in compliance with
electrical codes in force in your area, suitable to at least
10 Amp 250 Volt (220-230 Vo lts 50-60 Hz areas) and
20 Amp 250 Volt (100-115 Volts 50-60 Hz areas)
applications. Should you prefer to connect the unit directly
to the mains, connect the supply cord to a 2-pole wall
breaker, whose contact opening is at least 3 mm. Do not
use extension cords.
7 - Each drip tray has two diaphragm plugs: if a continuous
drain is needed, perforate one of the drain plugs and
connect it to a flexible drain line (see figure 1).

5 - Do not obstruct air intake and discharge openings: 15 cm
(6”) minimum air space all around the dispenser.
6 - Do not put objects or fingers in panels louvers and faucet
outlet.
7 - Do not remove bowls, augers and panels for cleaning or
routine maintenance unless the dispenser is disconnected
from its power source.
5 OPERATING PROCEDURES
1 - Clean and sanitize the unit according to the instructions in
this manual. See chapter 5.3 CLEANING AND
SANITIZING PROCEDURES.
2 - Fill the bowls with product to the maximum level mark. Do
not overfill.
The exact quantity of product (expressed as liters an d
gallons) is shown by marks on the bowl.
3 - In case of products to be diluted with 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.
4 - To obtain the best performance and result, use bases
designed to be run in Granita freezers. Such bases have a
sugar content of 34 degrees Baumé corresponding to 64
degrees Brix (equivalent to a specific gravity of about 1.3
kg/liter).
For Granita the bases are to be diluted with water on a 1
plus 4/4.5 basis.
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. The dispenser must always run with the
covers installed to prevent a possible contamination of the
product.
6 - 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 powe r 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 i s contro lle d
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 2).
figure 2
In addition all the models except MT 1 are equipped with an
automatic safety pressure switch to prevent damages to the
compressor. The lighting of the warning ligh t 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)
IMPORTANT
However Granita mix may be done, its Brix (sugar
percent content) must be at least 13.
0 position : power is turned OFF to all functions.
I position : power is turned ON to all functions
and the other switches are enabled.

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 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
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.
Note: beverage temperature is controlled by the
thermostat only when the mixer/refrigeration
switch(es) are in I position, Soft Drink mode.
3 - When the mixer / refrigeration switch(es) are set in I
position, Soft Drink mode, it is possible to manually switch
off the refrigeration by turning completely towards left
(counterclockwise) the thermostat knob until it clicks.
4 - 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.
5 - To shorten Granita recovery time and increase
productivity, it is advisable to pre-chill the product to be
used in the dispenser.
6 - 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.
7 - 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.
8 - 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.
9 - The 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.
10 -The 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
safety pressure switch warning light is OFF the unit is
running properly.
11 -Restrictor cap: when the unit is used in Soft Drink mode it
is advisable to install the restrictor cap on the faucet outlet
in order to reduce the drink outflow (see figure 5).
