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 volta ge 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 grou nded
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 H z areas)
applications. Should you prefer to connect th e 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.

IMPORTANT

Read electrical ratings written on the data plate of the
individual units; the data plate is adhered on the dispen ­sing side panel of the unit, just behind the drip tray (the
right side drip tray in multiple bowl models). The serial
number of the unit (preceded by the symbol #) is adhered
inside the left switch box. Data plate specifications will
always supersede the information in this manual.

The electric diagram of the dispenser is located in the inner
part of the dispensing side panel.

Specifications are subject to change without notice.

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

ATTENTION

Failure to provide proper electrical ground according to
applicable electrical codes could result in serious shock
hazard.

7 The 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).

IMPORTANT

Install the dispenser so that the plug is easily a ccessi­ble.

4 TO OPERATE SAFELY

1 Do not operate the dispenser without reading this

operator’s manual.
2 Do not operate the dispenser unless it is properly

grounded.

3 Do not use extension cords to connect the dispenser.

1 Remove the corrugate container and packing materials and

keep them for possible future use.

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.

4 Do not operate the dispenser unless all panels are
restrained with screws.

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

ATTENTION

In case of damages, the power cord must be repla ced by
qualified personnel only in order to prevent any shock
hazard.

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 and gallons)
is shown by marks on the bowl.

3 In case of products to be dilute d 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.

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.
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.

IMPORTANT

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)

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.

Operate the dispenser with food products only.

IMPORTANT

However Granita mix may be done, its Brix (sugar
percent content) must be at least 13.

5 Set the control switches as shown in chapter

5.1 DESCRIPTION OF CONTROLS.
6 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. 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 contro lled
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

Mixer/refrigeration switch (B)

I position : mixer and refrigeration ON.

SOFT DRINK mode.
0 position : OFF.

GRANITA mode.

Thermostat (D)

Turn clockwise : to decrease temperature
Turn counterclockwise : to increase temperature

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.

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):

- 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

MT MINI UL

(the indicator F will go up in opening G).

figure 3

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 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, wh ich could resu lt
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 accumulati on 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.

8 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.

9 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
pressure switch warning light is OFF the unit is running
properly.

10 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 4).

5. 3 CLEANING AND SANITIZING
PROCEDURES

1 Cleaning 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.

2 Prior 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
