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, pour water into

bowl first, then add correct quantity of product. In case of natural

particulates, 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 us ed, dissolve 5.3 - 7 oz. of

sugar per 0.25 gallons.

in switch panels protected by switch covers (see figure 1).

figure 1

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

ENGLISH

IMPORTANT

However Granita mix may be done, its Brix (sugar percent content) must be at least 13.

IMPORTANT

Operate the dispenser with food products only.

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 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

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.

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).

4 - The le ngth 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

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 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.
