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 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 Vo lts 50-60 Hz areas) and 20 Amp 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.
ATTENTION
Failure to provide proper electrical ground accordi ng 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. a ccording to this handbook instructions (chapter
5.3 CLEANING AND SANITIZING PROCEDURES).
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 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 us e 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 fa ucet
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
1 - Clean and sani tize the unit accordi ng to the instruction s in
this manual. See chapter 5.3 CLEANING AND
SANITIZING PROCEDURES. 2 - Fill the bowls with product to th e 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 (equivalent to a specific grav ity of about 1.3
kg/liter).
4 Ugolini spa
MT UL
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.
IMPORTANT
However Granita mix may be done, its Brix (sugar percent content) must be at least 13.
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.
follows:

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.
5. 1 DESCRIPTION OF CONTROLS
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).

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 - Gra nita viscosity adjustment : proper Gran ita 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):
figure 1
With reference to figure 3 dispenser controls functions are as
- 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).

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 do wn 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” 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.
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).

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 mach ine 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.
