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 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.
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
in switch panels protected by switch covers (see figure 1).
figure 1
With reference to figure 3 dispenser controls functions are as
follows:

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.
ATTENTION
In case of damages, the power cord must be replaced
by qualified personnel only in order to prevent any
shock hazard.
IMPORTANT
However Granita mix may be done, its Brix (sugar
percent content) must be at least 13.

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).
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 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.
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).

1 INTRODUCTION
This operator’s manual is a complement to the standard
Granita machine operator’s manual available in the unit
package.
Carefully read first the standard unit Operator’s Manual and
then all the following sections of this one thoroughly to
familiarize yourself with all aspects of the system.
The purpose of the Autofill Device is to increase the
productivity of a Granita Machine far beyond the containers
capacity, allowing the automatic refill as soon as the product in
the containers drops lower a preset level.
In order to operate a Granita Machine equipped with Autofill
Devices a remote fill system is required.
The remote fill system is composed of all those parts that are
installed outside the dispenser and is intended to supply the
dispenser with the adequate and correct beverage to be
frozen.
It is not the aim of this manual to instruct about how to set up
and operate a remote fill system. To get more information
about that please make reference to our “Autofill System for
Granita Machines - General description and typical installation
flow charts”.
2 INSTALLATION
1 - Loosen the fitting locker located on the rear cover of each
bowl equipped with Autofill Device and connect the remote
fill system using a 1/4” fitting suitable to the purpose.
Tighten the fitting locker.
2 - On the lower rear panel of the machine a 6-pole terminal
block is located. It is designed for connecting some
accessories such as a Safety Water Line Solenoid Valve
and one Sold-out Switch each bowl (see figure 1).
figure 1
3 - The Safety Water Line Solenoid Valve is intended to cut off
the main water line (if present in the remote fill system)
whenever the Autofill Device is not refilling.
The Sold-out Switch (one for each bowl) disables the
Autofill Device and activates acoustic and visual alarms
whenever the incoming beverage is sold out.
The Safety Water Line Solenoid Valve, if present, must be
connected to the unit using #1 and #2 poles of the
terminal block (see figure 1).
If a Safety Water Line Solenoid Valve is not used do not
use #1 and #2 poles.
If the remote fill system is equipped with Sold-out switches
connect their wires to #3 and #4 poles (for one bowl unit),
to #3, #4 and #5 poles (for two bowls unit) and to #3, #4,
#5 and #6 poles (for three bowls unit) as per figure 1
diagram.
4 - The Autofill Device doesn’t come presanitized from the
factory. Prior to starting operation an In-Place Sanitization
is to be performed according with this handbook
instructions (paragraph 3.3 IN-PLACE SANITIZATION).
3 OPERATING PROCEDURES
Once the remote fill system is set up, follow the procedures
described in chapter 3.1 DESCRIPTION OF CONTROLS to
activate the Autofill system.
If the clip probe is properly installed and the bowl properly fitted
in their position, the remote fill system starts to operate and
feed the bowl through the hole in the rear wall. As soon as the
product level reaches the lowest tip of the probe, the priming
automatically stops.
As soon as the probe tip immersed in the product gets
uncovered (because of dispensed product), the solenoid valve
inside the rear wall automatically opens and fresh beverage
flows into the bowl until the probe tip gets covered again.
The solenoid valve opening occurs with about 10 seconds
delay to avoid that the irregular waving of product surface,
occasionally discovering probe tip, may be understood as level
dropping “cause of dispensing”.
A sold-out warning light along with a buzzer (visual and
acoustic sold-out alarms) are located respectively on and
inside the rear cover. They can run only if an applicable Sold-
out switch is connected to the terminal block (see figure 1).
3. 1 DESCRIPTION OF CONTROLS
Each Autofill Device is equipped with a three position switch
IMPORTANT
Whatever the remote fill system may be make sure that
the inlet product pressure into the Autofill Device is not
exceeding 2.5 bar (36 psi).
IMPORTANT
Safety Water Line Solenoid Valve must be 24V DC 12W
maximum.
IMPORTANT
If no Sold-out switch is used make sure that #3, #4, #5
and #6 poles on the terminal block are connected
together.
IMPORTANT
The device is designed so as no refilling occurs in case
either the clip probe is not properly installed or the bowl
not properly fitted.

located on the rear wall.
Its functions are as follows:
To operate the Autofill Device:
1 - Set the power switch of the unit to I position.
2 - If it is first time operation: manually energize the Autofill
Device, by keeping pushed the Autofill Switch in position II,
until the priming is completed. Set the Autofill switch to I
position.
If this is not first time operation: set Autofill switch to I
position.
3 - Set the unit mixer/refrigeration switch of the bowl to
II position.
Note: when Autofill switch is set to position 0, the unit performs
as a standard unit not equipped with Autofill Device.
3. 2 OPERATIONAL HELPFUL HINTS
1 - When the remote fill system is equipped with Sold-out
switches if a product sold-out occurs the Autofill Device
automatically stops and acoustic and visual alarms are
activated. Once product is restored, by keeping manually
pushed the Autofill switch (located in the rear wall) in II
position, it is possible to manually reactivate the remote fill
system as already told in 3.1.
2 - The 1.25 Amps Fuse located near the terminal block has
the purpose to protect the Autofill Devices from short
circuits or overloads on #1 and #2 poles.
3 - After cleaning and sanitizing procedures carefully dry the
bowl and the clip probe to avoid that the water present on
the bowl may be understood as level reaching the probe
and “causing of stopping of the refill”.
3. 3 IN-PLACE SANITIZATION
The In-Place Sanitization of the Autofill system is
recommended to guarantee 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.
Prior to perform the In-Place Sanitization the machine must be
emptied of product. To do this proceed as follows:
1 - Use a clean tank for each of the following:
a -Cleaning Tank - fill with warm (45-60 °C / 120 - 140 °F)
potable water.
b -Sanitizing Tank - fill with sanitizing solution (100 PPM
available chlorine concentration or 1 spoon of sodium
hypoclorite diluted with half a gallon of water) according
to your local Health Codes and manufacturer’s
specifications.
2 - Repeat the following procedure on each of the unit bowls:
a -Disconnect the beverage source and in place of it
connect the Cleaning Tank to the remote fill system line.
b -Set the unit Power Switch to position I. Manually
energize the Autofill Device, by keeping pushed the
Autofill Switch (located on the rear cover of each bowl)
in position II, until the cleaning water flows free from any
beverage residue.
Set the unit Power Switch to position 0 and drain all the
liquid from the bowl.

5 INSTRUCCIONES DE EMPLEO
1 - Lavar e higienizar el distribuidor antes de utilizarlo
siguiendo cuanto se ha dicho en las presentes
instrucciones en el capítulo 5.3 LIMPIEZA.
2 - Llenar los contenedores con el producto deseado hasta
que alcance el nivel máximo indicado (no superar dicho
nivel).
La cantidad de producto presente en el contenedor (en
litros o en galones) está indicada con señales específicas
situadas en el contenedor mismo.
3 - Si se quiere distribuir productos concentrados a diluirse
con agua, verter en los contenedores el agua agregando a
continuación la cantidad necesaria de producto
concentrado, según las instrucciones del fabricante. Si se
quieren emplear zumos naturales se recomienda filtrarlos
para evitar que las partes sólidas puedan obstruir el
pasaje del grifo.
4 - Para obtener los mejores resultados emplear como
productos base, jarabes expresamente preparados para
Granizado.
Si se desea obtener una bebida en vez de un granizado,
cada litro de jarabe debe ser diluido con 5-5,5 litros de
agua (1 litro más respecto del necesario para el
granizado).
Es una buena regla seguir las instrucciones dictadas por
el fabricante de jarabes.
Si se usan productos naturales (por ejemplo zumo de
limón o naranja) o bien bebidas no azucaradas (por
ejemplo café), disolver 150-200 gramos de azúcar por
cada litro de producto.
5 - Montar las tapas sobre los contenedores cerciorándose
que queden bien colocadas y que se establezca una
correcta conexión eléctrica entre el contenedor y la tapa.
6 - Accionar los interruptores (ver capítulo 5.1 DESCRIPCIÓN
DE LOS MANDOS).
7 - El distribuidor debe funcionar siempre con las tapas
montadas para prevenir una posible contaminación del
producto.
8 - El distribuidor debe funcionar ininterrumpidamente: el
grupo frigorífico se parará automáticamente cuando el
producto esté listo para ser distribuido. Los dispositivos
mezcladores seguirán funcionando.
5. 1 DESCRIPCION DE LOS MANDOS
El distribuidor está provisto de un interruptor general y de un
interruptor para la luz. Cada uno de los contenedores está
provisto de un interruptor para arrancar la mezcla y para
seleccionar el tipo de refrigeración del producto. En efecto, es
posible obtener tanto bebidas frías como productos helados
como granizados o sorbetes.
Cuando se selecciona la función bebida, la temperatura de
dicha bebida está regulada por el correspondiente termostato.
Cuando se selecciona la función granizado la densidad del
producto se regula con el correspondiente tornillo de ajuste
que se encuentra en cada una de las paredes posteriores del
distribuidor (para regular la temperatura y la densidad ver el
capítulo 5.2 SUGERENCIAS).
Todos los interruptores están colocados en la parte frontal del
distribuidor (lado grifos) y están protegidos con una ventanilla
apropiada (ver figura 1).
figura 1
Las funciones de los mandos del distribuidor se ilustran a
continuación:
figura 2
Interruptor general (A)
Interruptor luces (E)
Interruptor mezcladores y refrigeración (B)
Termostato (D)
Para el funcionamiento del distribuidor:
1 - Colocar el interruptor general en la posición I.
ATENCION
Si el cable de alimentación está dañado, debe ser
substituito por el fabricante o desde su servicio de
asistencia técnica o, en cualquier caso, por una
persona cualificada con el fin de evitar cualquier tipo de
riesgo.
IMPORTANTE
En todo caso, una vez obtenida la mezcla, su grado de
Brix (porcentaje de azúcar) debe ser superior a 13.
IMPORTANTE
Utilizar el distribuidor solamente con productos
alimenticios.

2 - Ajustar los interruptores mezcladores y refrigeración:
- en la posición I si se quiere refrigerar el producto sin
helarlo
- en la posición II si se quiere obtener el granizado.
3 - Poner el interruptor luces en la posición I para encender
las luces.
5. 2 SUGERENCIAS
1 - Regulación de la densidad: la densidad óptima del
granizado ha sido ya ajustada en fábrica. Si se quiere
variar dicha densidad girar con un destornillador el
correspondiente tornillo de ajuste situado en cada una de
las paredes posteriores del distribuidor (ver figura 3):
- hacia derecha (sentido horario) para obtener un
granizado más denso (el índice F en la ventanilla G se
desplazará hacia abajo).
- hacia izquierda (sentido antihorario) para obtener un
granizado menos denso (el índice F en la ventanilla G se
desplazará hacia arriba).
figura 3
2 - Regulación de la temperatura: la temperatura óptima de
las bebidas (para el funcionamiento del distribuidor como
refrigerador de bebidas y no como granizador) ha sido
regulada en la fábrica. Si se quiere variar su valor, girar el
pomo colocado en cada una de los paneles
portainterruptores:
- hacia derecha (sentido horario) para obtener una bebida
más fría.
- hacia izquierda (sentido antihorario) para obtener una
bebida menos fría.
NOTA : la regulación de la temperatura de la bebida se
hace efectiva solamente cuando el interruptor
mezcladores y refrigeración correspondiente se
encuentra en la posición Bebida.
3 - El tiempo necesario para obtener la refrigeración del
producto varía en función de distintos factores como por
ejemplo la temperatura ambiente, la temperatura inicial del
producto, su contenido de azúcar (grado Brix) y la
regulación de la densidad.
4 - Llenando los contenedores con producto ya enfriado
previamente se aumenta ulteriormente la eficiencia del
distribuidor.
5 - Para disminuir los tiempos de restablecimiento y, por lo
tanto, aumentar la autonomía del distribuidor, volver a
llenar cuando el nivel del producto desciende a mitad
evaporador.
6 - Para conseguir una buena conservación del producto, el
distribuidor debe funcionar también durante la noche, por
lo menos en la posición Bebida. Si esto no fuera posible y
los productos permanecieran en los contenedores con el
distribuidor parado es conveniente, una hora antes de
apagar el aparato, llevar los interruptores mezcladores y
refrigeración en la posición I; ésto evita la formación de
bloques o crostas de hielo que podrían dañar los
dispositivos mezcladores. En el caso en que se formasen
dichos bloques de hielo, estos deberían ser quitados antes
de volver a poner en función el distribuidor. El
funcionamiento nocturno en la posición Bebida elimina
además la posible formación de hielo (debido a la
condensación de la humedad atmosférica) en el exterior
de los contenedores.
7 - No parar jamás los mezcladores cuando hay granizado en
los contenedores; si no se mezcla, dicho granizado puede
agregarse y formar un único bloque de hielo. Volviendo a
arrancar los mezcladores en estas condiciones (sin
esperar que el hielo se derrita) pueden dañarse.
8 - El distribuidor está provisto de una junta magnética para la
transmisión del movimiento a los mezcladores.Para
prevenir daños al aparato, en caso de bloqueo de los
mezcladores debido a bloques de hielo u otro dentro de
los contenedores, la junta magnética se encarga de
desconectar automáticamente la transmisión del
movimiento.
Dicha situación puede ser identificada tanto por el bloqueo
de los mezcladores como por un ruído intermitente que
proviene del aparato. En este caso es necesario parar
inmediatamente el distribuidor, vaciar el contenedor
interesado y eliminar la causa del bloqueo.
9 - Reductor del flujo: cuando el distribuidor se utiliza para la
refrigeración de bebidas se aconseja instalar, sobre el
grifo, el reductor de flujo provisto (ver figura 4).

5. 3 LIMPIEZA
1 - La limpieza y el lavado son fundamentales para garantizar
la perfecta conservación del gusto de la bebida y la
máxima eficiencia de vuestro distribuidor. Los
procedimientos descritos a continuación deben ser
considerados de carácter general y pueden variar por
efecto de la reglamentación de higiene vigente.
2 - Antes del desarmado para el lavado del distribuidor debe
quitarse todo el producto. Proceder como sigue:
-poner el interruptor general en la posición I;
-poner los interruptores mezcladores/refrigeración en la
