2 - Inspect the uncrated unit for any possible damage. If damage
is found, call the delivering carrier immediately 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
MT 3
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 Volts 50-60 Hz
areas) and 20Amp 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).
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
1 - Remove the corrugate container and packing materials and
keep them for possible future use.
8- 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 SANITIZING
PROCEDURES).
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.
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

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 and 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 Baume 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.
in switch panels protected by switch covers (see 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 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:
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 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
