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

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

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).

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).

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

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.

To operate the defrost timer proceed as follows (see figure 19).
1 - Set the time of the day by rotating the dial clockwise (arrow A).

6.1 MAINTENANCE (TO BE CARRIED OUT BY
QUALIFIED SERVICE PERSONNEL ONLY)

1 - Monthly 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.

2 - Annually: remove the panels and clean the inside of the

machine including the base, side panels, condenser, etc.

3 - Never 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.

4 - In 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.

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.

2 - Program 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).

7 DEFROST TIMER (OPTIONAL)

The Defrost Timer, located on the right side of the unit,
automatically switches the dispenser from Granita mode to Soft
