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.

INSTALLATION

• 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.

• Inspect the uncrated unit for any possible damage. If damage is found, call the delivering carrier immediately to file a claim.

• 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.

• A minimum of 15 cm (6”) of free air space all around the unit should be allowed to guarantee adequate ventilation.

• 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.

• 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 Volts 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 according to applicable electrical codes could result in serious shock hazard.

• 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 accessi-ble.

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.
8. Do not pour food product inside the dispenser at a temperature higher than 40°C.

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.
   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.

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 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).

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

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.

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.

OPERATION HELPFUL HINTS

• 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).

• 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.

• 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.

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

• 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.

• 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.

• 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.

• 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.

CLEANING AND SANITIZING PROCEDURES

• 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.
• 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

5. Use fresh product to chase any remaining sanitizer from the bottom of the bowl(s). Drain this solution. Do not rinse out the machine.

ROUTINE MAINTENANCE

1. Daily: inspect the machine for signs of product leaks past seals and gaskets. If proper assembly does not stop leaks around seals or gaskets, check for improper lubrication, worn or damaged parts. Replace parts as needed.
2. Monthly on MT 1P, MT 2 and MT 3 models: remove the dust from the condenser filter. A blocked filter will reduce

ATTENTION
Before any disassembly and/or cleaning procedure make sure that the dispenser is disconnected from its power source by unplugging it or switching off the 2-pole wall breaker. performance and could cause compressor failure.
Remove the only left panel (from faucet side) unscrewing the two plastic coated screws (see figure 15).

ATTENTION
Condenser fins are very sharp. Use extreme caution when cleaning.

• Replacement of lighted top cover bulb: remove the fixing screw placed in the upper part of the top cover, remove the lower part and replace the bulb (using a 24-28V 21W max bulb). Reassemble the top cover and replace the fixing screw.(see figure 16)

MAINTENANCE (TO BE CARRIED OUT BY QUALIFIED SERVICE PERSONNEL ONLY)

• Monthly on MT 1 model: remove the dust from the condenser. To do this unplug the unit or switch off the 2-pole wall breaker and then remove the panels.
• Annually: remove the panels and clean the inside of the machine including the base, side panels, condenser, etc.
• Annually: Check if the auger bushings are worn out or ovalized. If they are, replace them with new ones.
• Never remove the insulating jacket from around the suction tubing of the evaporator (the copper tubing located on the right side of gear motor). In case the insulating jacket is missing replace the entire parts with original spare parts from the supplier.
• In order to prevent any damages to the dispenser, all plastics parts must be lubricated only with grease supplied by the manufacturer or with another lubricating product suitable for polycarbonate.

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.

To operate the defrost timer proceed as follows (see figure 17).

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). Note: when all the tabs are pushed in the defrost function is OFF (the machine operates as if it were not equipped with Defrost Timer).
