combined weight of dispenser and product bearing in mind
what is stated in the preceding point 1 IMPORTANT
warning.
4A minimum of 15 cm (6”) of free air space all around the unit
should be allowed to guarantee adequate ventilation.
5Ensure 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.
6Before 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 Volts 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.
7The unit doesn’t come presanitized from the factory. Before
serving products, the dispenser must be disassembled,
cleaned and sanitized according to this handbook instructions
(chapter 5.3 CLEANING AND SANITAZING PROCEDURES).

this manual. See chapter 5.3 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 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
5.1 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.
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
With reference to figure 3 dispenser controls functions are as
follows:
figure 2
Power switch (A)
Light switch (E)
Mixer/refrigeration switch (B)
Thermostat (D)
To operate the unit:
1Set the power switch to I position.
2Set the mixer/refrigeration switches as follows:
- to the I position to get soft drink.
- to the II position to get Granita.
3Set the light switch to I position.
5. 2 OPERATION HELPFUL HINTS
1Granita 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):
- 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
IMPORTANT
Operate the dispenser with food products only.
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. The fan motor runs.
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.
I position :mixer and refrigeration ON.
SOFT DRINK mode.
0 position :OFF.
II position :mixer and refrigeration ON.

(the indicator F will go up in opening G).
figure 3
2Beverage 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.
3The 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.
4To shorten Granita recovery time and increase productivity,
it is advisable to pre-chill the product to be used in the
dispenser.
5To 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.
6For 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.
7Mixers 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.
8The 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.
9The 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.
5. 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
only and is subject to the requirements of the local Health
Authorities.
2Prior to the disassembly and cleaning, the machine must be
emptied of product. To do this proceed as follows:
- set the power switch to I position
- set mixer/refrigeration switch(es) to I position (Soft Drink
mode)
- place a pail under each faucet and drain all product from
bowls
- set all control switches to the 0 position

snugly around the gasket and its front fastening hooks are
properly engaged (see figure 14).
figure 14
8Use fresh product to chase any remaining sanitizer from the
bottom of the bowl(s). Drain this solution. Do not rinse out the
machine.
5. 4 IN-PLACE SANITIZATION
The In-Place Sanitization prior to starting the machine may
be performed, if needed, only as further precaution, in
addition to the Disassembled Parts Sanitization described
before, but never in lieu of it.
1Prepare two gallons of a warm (45-60°C, 120-140 °F)
sanitizing solution (100 PPM available chlorine concentration or
1 spoon of sodium hypoclorite diluted with 2 liters of water)
according to your local Health Codes and manufacturer’s
specifications.
2Pour the solution into the bowl(s).
3Using a brush suitable for the purpose, wipe the solution on
all surfaces protruding above the solution-level and on the
underside of the top cover(s).
4Install the top cover(s) and operate the unit. Allow the
solution to agitate for about two minutes. Drain the solution out
of the bowl(s).
5Use fresh product to chase any remaining sanitizer from the
bottom of the bowl(s). Drain this solution. Do not rinse out the
machine.
6 ROUTINE MAINTENANCE
1Daily: inspect the machine for signs of product leaks past
seals and gaskets. If proper assembly does not stop leaks
around seals or gaskets, check for improper lubrication, worn
or damaged parts. Replace parts as needed.
2Monthly on MT 1P, MT 2 and MT 3 models: remove the
dust from the condenser filter. A blocked filter will reduce
performance and could cause compressor failure.
Remove the only left panel (from faucet side) unscrewing the

3Replacement of lighted top cover bulb: remove the fixing
screw placed in the upper part of the top cover, remove the
lower part and replace the bulb (using a 24-28V 21W max
bulb). Reassemble the top cover and replace the fixing
screw.(see figure 16)
figure 16
6. 1 MAINTENANCE (TO BE CARRIED OUT BY
QUALIFIED SERVICE PERSONNEL ONLY)
1Monthly on MT 1 model: remove the dust from the
condenser. To do this unplug the unit or switch off the 2-pole
wall breaker and then remove the panels.
2Annually: remove the panels and clean the inside of the
machine including the base, side panels, condenser, etc.
3Annually: Check if the auger bushings are worn out or
ovalized. If they are, replace them with new ones.
4Never remove the insulating jacket from around the suction
tubing of the evaporator (the copper tubing located on the right
side of gear motor). In case the insulating jacket is missing
replace the entire parts with original spare parts from the
supplier.
5In order to prevent any damages to the dispenser, all
plastics parts must be lubricated only with grease supplied by
the manufacturer or with another lubricating product suitable for
polycarbonate.
7 DEFROST TIMER
The Defrost Timer, located on the right side of the unit,
automatically switches the dispenser from Granita mode to Soft
Drink 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.
figure 17
To operate the defrost timer proceed as follows (see figure 17).
1Set the time of the day by rotating the dial clockwise (arrow
A). Never rotate the timer counterclockwise as this would
damage the internal mechanism. Align the current time of day
with the arrow B on the timer face. This is a 24 hour timer
showing both A.M. and P.M.
2Program the defrost timer by pushing out on the tabs C that
correspond to the hours desired to defrost. Each tab represents
15 minutes. A minimum of four to eight hours are required to
defrost frozen beverage (depending on ambient conditions).
Note: when all the tabs are pushed in the defrost function is OFF
(the machine operates as if it were not equipped with Defrost
Timer).
ATTENTION
Condenser fins are very sharp. Use extreme caution
when cleaning.
