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 an d
cleaning. It is strongly recommended that personnel
responsible for the equipment’s daily operations, disassembly,
cleaning, sanitizing and assembly, go through thes e
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.

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.

2 - Inspect the uncrated unit for any possible damage. If

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

routine maintenance unless the dispenser is disconnected

from its power source.

5 OPERATING PROCEDURES

ATTENTION

In case of damages, the power cord must be replaced
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

5

MT UL BL

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.
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 5.3 - 7 oz of sugar

per 0.25 gallons.

IMPORTANT

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

IMPORTANT

Operate the dispenser with food products only.

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

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.

Light switch (E)

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.

Mixer/refrigeration switch (B)

I position : mixer and refrigeration ON.

SOFT DRINK mode.
0 position : OFF.
II position : mixer and refrigeration ON.

GRANITA mode.

The dispenser is equipped with a p ower 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 viscos ity is co ntrolle 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 1).

figure 1

With reference to figure 3 dispenser controls functions are as

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.

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

MT UL BL

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 4).

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 - 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” abl e
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.

inner part of the dispensing side panel.

7 DEFROST TIMER (OPTIONAL)

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.

MT UL BL

figure 18

To operate the defrost timer proceed as follows (see figure 18).

1 - Set 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.

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).
