INTRODUCTION

It is necessary to 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 in charge to 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.

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 damage is found, call the delivering carrier immediately to file a claim.

3. Install the unit on a counter top that will support the combined weight of dispenser and product bearing in 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.
   ATTENTION
   Failure to provide proper electrical ground according to applicable electrical codes could result in serious shock hazard.

6. 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).

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 7.3 CLEANING AND SANITAZING PROCEDURES).

IMPORTANT
Install the dispenser so that the plug is easily accessible.

TO OPERATE PROPERLY AND 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 operate the dispenser unless all panels are restrained with screws.
4. Do not put objects or fingers in panels louvers and faucet outlet.
5. Do not remove bowls, augers and panels for cleaning or routine maintenance unless the dispenser is disconnected from its power source.
6. The cover must be always closed.
7. Do not pour food product inside the dispenser at a temperature higher than 40°C.

OPERATING PROCEDURES

1. Clean and sanitize the unit according to the instructions in this manual. See chapter 7.3 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.
   IMPORTANT
   Operate the dispenser with food products only.
   IMPORTANT
   However Granita mix may be done, its Brix (sugar per-cent content) must be at least 13.

5. Set the control switches as shown in chapter 7.1 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.

7. If you use the dispenser with milk-based products, never switch it off. When not in use activate the storage function.

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

OPERATION HELPFUL HINTS).
All the switches are located on the faucet side of the dispenser in switch panels protected by switch covers (see figure 2).

With reference to figure 3 dispenser controls functions are as follows:

Power switch (A)

• position: power is turned OFF to all functions.
• position: power is turned ON to all functions and the other switches are enabled. The fan motor runs.

Mixer/refrigeration switch (B)

• position: mixer and refrigeration ON. SOFT DRINK mode.
• position: OFF.
• position: mixer and refrigeration ON. GRANITA mode

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:
3. to the I position to get soft drink.
4. to the II position to get Granita.

ETC VERSION
Dispenser controls functions are as follows (see figure 2).

Power switch (A)

0 position: power is turned OFF to all functions.
I position: power is turned ON to all functions . The fan motor runs. On single bowl machines mixers run too.

Mixer/Refrigeration switches ( C) and (D)

Switch C : if pressed it activates the function ‘DRINK’. In this case the (E) led lights up.

Switch D : if pressed it activates the function ‘SLUSH’. In this case the (F) led lights up.

In machines with several tanks, pressing the key relating to the activated operating mode will then make it possible to switch off both mixing and freezing of the corresponding tank. As a result, the mixer will stop and the two indicator lights (E) and (F) will switch off. Pressing one of the two keys (C) or (D) makes it possible to reactivate the corresponding function.

Thermostat (B)
It displays the temperature of product inside the bowl.
Temperature alarm : if the temperature on display flashes, it means that product remained for a certain period at a temperature higher than the max. admitted conservation temperature , and therefore it is necessary to check the product conditions.
Press for three seconds the button (D) to reset the display .

IMPORTANT
If the dispenser is switched on when bowls contain pro-ducts at a temperature higher than conservation tempe-rature, 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) simultaneously for two seconds. The indicator light (E) and the temperature set will flash and you can adjust it using keys (C) and (D). The display will go blank for a few seconds and then the current temperature will be displayed.
• Minimum temperature adjustment in GRANITA mode: you can also adjust the minimum temperature of the product when the dispenser is operating in granita mode. This minimum temperature is factory set to -10°C. If you want to adjust it, hold down keys (C) and (D) simultaneously for two seconds to go into drink temperature adjustment mode and the indicator light (E) will flash. Press keys (C) and (D) for two seconds to go into granita minimum temperature adjustment mode and the indicator light (F) and temperature set will flash. You can adjust the temperature using keys (C) and (D). The display will go blank for a few seconds and then the current temperature will be displayed.

To operate the unit :

Set the power switch to I position
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.

OPERATION HELPFUL HINTS

1. Granita viscosity adjustment: proper Granita viscosity isfactory 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 5):

2. towards right (clockwise) to obtain a thicker product (the indicator F will go down in opening G).

3. towards left (counterclockwise) to obtain a thinner product (the indicator F will go up in opening G).

4. Temperature adjustment: the optimal temperature of drinks (when the dispenser works as a drinks cooler rather than as an ice crusher) is factory set. If you want to adjust this temperature, turn the knob in each switch box:
   – to the right (clockwise) for a cooler drink.
   – to the right (anticlockwise) for a less cool drink.
   Note: beverage temperature is controlled by the thermostat only when the mixer/refrigeration switch(es) are in I position, Soft Drink mode.

5. 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.

6. To shorten Granita recovery time and increase productivity, it is advisable to pre-chill the product to be used in the dispenser.

7. 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.

8. 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.

9. 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.

10. 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.

11. The dispenser must be able to emit heat.
    In case it seems excessive, check that no heating source is close to the unit and airflow 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 the unit is running properly.

12. The product is for use with confectionery only.

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
