number of the unit (preceded by the symbol #) is adhered
inside the left switch box. In the ETC model the serial
numbers are located underneath the machine or on the
evaporator holder level when the side panels are removed. 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 accessible.
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

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 gallons)
is shown by marks on the bowl.
3 In case of products to be diluted 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.
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
IMPORTANT
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 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

3 Set the power switch to I position
4 For each container select :
-Button (C) to get cold drink ( without freezing it)
-Button (D) to get slush
Cleaning function: during sanitizing operations, it may be useful
to have the mixers turning , without cooling. To get this, press for
three seconds the button (C ) : the display of thermostat will
show "--.-- "
By pressing any button, the dispenser will get out from cleaning
function and will operate normally.
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).
IMPORTANT
If the dispenser is switched on when bowls contain products at a temperature higher than conservation temperature, the display will flash. To have a fixed display , it
is necessary to press for three seconds the button (D).
IMPORTANT
Conservation temperature is set at the factory at 4°C.
Cleaning mode: hold down key (C) for three seconds to enable
CLEANING mode, during which the display shows " --.-- ". In
this mode, the mixer turns but the cooling is not enabled. This
function is useful during machine rinsing, washing and sanitising
to prevent the contents of the unit from being cooled. It is
nonetheless always possible to quit cleaning mode simply by
pressing any key.
Temperature adjustment in DRINK mode: the optimal
temperature of drinks (when the dispenser works as a drinks
cooler rather than as an ice crusher) is factory set to 4°C. If you
want to adjust the temperature, hold down keys (C) and (D)
figure 4
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
6
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.
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.
