ICE RECOMMENDED FOR DISPENSING

Dispensers are designed to dispense hard, cube ice up to one-inch square. The ice shapes and sizes listed above are recommended for dispensing. W arm “Sup er Cooled” Ice Before Dispensing: “Super Cooled” ice is not recommended for dispensing. “Super cooled” ice is ice th at has been stored in freezers below 32°F. must it be necessary to temporarily use “super cooled” ice, allow the ice to warm at room temperature for 25 to 30 minutes before placing the ice in the dispenser.

NOTE: Manitowoc Half Dice Ice has been shown to give the best performance in the IcePic dispenser . Hoshizaki America, Inc., ice machines with cresent-style shape cubes are compatible with this dispenser but not recommended.

Part Number 5010330 10/09 3-3

NON-ADJUSTABLE AGITATION TIMER

The timer is non-adjustable and is set to agitate the ice for 3 seconds every 3.5 hours. Activating the dispenser will reset the timer. After 3.5hours of non-use, the timer will energize the dispenser motor .

The LED tells the technician in which mode the timer is operating. Rather than a jumper pin, this timer has a female spade connector that must be connected to terminal number 6.

When this jumper is in place, the LED will blink at one second intervals, this is the run mode.

When the jumper is open, the LED will flash every

0.4 second. This is the test mode and the timer will cycle every 55 seconds in test mode. If the timer is left in test mode, it will automatically reset to run mode.

Operation Section 3

ICE STORAGE AND DISPENSING

As the customer presses the rocking chute, the arm at the top left rear of the chute pushes upward on the door lock. The door opens until it contacts the sto ps in the mounting brackets. The plastic arm on the ice chute also activates the lever of the ice dispensin g switch. When activated, the micro switch starts the gear motor. The gear motor turns the paddle wheel and agitator arm.

The paddlewheel carries ice. Periodic agitation is standard on the 30" and larger dispensers. During periodic agitation, the paddle wheel and agitator turn for approximate ly three seconds every three and one half-hours. The door lock prevents ice from being dispensed during the ag itation cycle.

Rocking Chute Ice Dispensing

As the customer presses the rocking chute, the arm at the top left rear of the chute pushes upward on the door lock. The door opens until it contacts the stops in the mounting brackets. The plastic arm on the ice ch ute also activates the lever of the ice dispensing switch. When activated, the micro switch starts the gear motor. The gear motor turns the paddle wheel and agitator bar.

Crushed Ice Dispensing

As a customer presses the ice chute the rocking chute door lifts and actuates micro switch which initiates the crushed ice dispensing process. When activated, the micro switch starts the gear motor and ice crusher motor . The gear motor turns the paddle wheel and U-bar agitator. The paddle wheel carries ice to the crusher assembly. Once the ice reaches the crusher housing, four stationary blades and three rotating blades crush the ice and push it through the opening in the ice crusher housing. The crushed ice then falls through the opening into the ice chute, and into the customer’s cup.

Operation

Carbon Dioxide (CO

) leaves the storage tank and

arrives at the carbonator tank through the gas inlet. Water supply enters the carbonator pump inlet at regular street water line pressure (minimum 20 PSI, maximum 80 PSI, dynamic or flowing pressure). The water pump increases the pressure of the water, which allows the water to flow into the carbonator tank. The CO

and the

water mix together in the carbonator to produce the carbonated water that is then sent to the soda dispenser.

The agitation of the water and CO

together in the tank

under high pressure creates the soda water. The quality of carbonation (percent of CO

mixed in the water)

increases as the water temperature decreases and exposure time increases.

The water level in the carbonator tank is controlled by a water level control in the tank. This control turns the pump motor off and on to maintain a preset level of liqu id in the tank. The water level control may be electronic probes or a mechanical float.

SYRUP DELIVERY SYSTEM

Your syrup location can vary depending on the volume of beverages served and ease of accessibility. Your beverage system may set in a back storage room or under the counter of the dispenser. Configurations are almost limitless. Check the temperatures expected for the storage location. Adverse temperatures can affect the storage and quality of beverage products. It is recommended the temperature of storage location should not fall below 40°F (4°C) or rise above 90°F (32°C).

CARBONATION

The purpose of the carbonator is to take regular tap water at street water pressure (minimum 20 PSI, maximum 80 PSI, dynamic or flowing pressure) 1/2" water line and increase the water to beverage system pressure (usually 100 PSI). This water is then combined with the CO same pressure, the CO

gas. Because the water and gas are at the

will dissolve into the water.

Chilling the mixture before dispensing will assist in locking the carbon dioxide into the water. After dispensing, the CO The CO

will gradually leave the liquid due to pressure

and temperature changes.

Components

The components of the carbonator are: water pump, an electric motor to operate the pump, carbonator tank where the water and CO

mix, and a water level control.

Racking

Regardless if you are working on a B-I-B or Figal system, a place will be designated for placement of the product. A rack (or shelf) system affords systematic placement and complete usage of the beverage paid for. The B-I-B rack allows the boxes to lay properly for syrup dispersal. Please check with your B-I-B syrup supplier. Some boxes must be

slightly tilted down, while others may be in virtually any position. The Figal tank rack keeps the newer an d full tanks organized at one end of the beverage line with the partial tanks at the other .

B-I-B

The Bag-In-Box system refers to a plastic disposable bag. The B-I-B normally contains 5 gallons of syrup, however some locations offer 2-1/2 gallon B-I-B unit s. This plastic bag is then held inside a cardboard or other container. B-I-B systems are for post-mix applications only .

Pumps

The syrup in a B-I-B system is delivered to the beverage system through gas operated pumps. These pumps extract the syrup out of the bags, forcing the syrup throughout the system.

Auto Bag Selectors

These are used on higher volume B-I-B systems where two or more bags of the same product are connected to one pump and one system. An auto bag selector is essentially a valve that automatically changes from one bag (or series of bags) to another bag (or series of bags) of syru p as the bags empty, allowing a constant flow of product.

FIGAL SYSTEM

Figal refers to the stainless steel tanks of pre-mix bevera ge or post-mix syrup. A small CO

tank pushes the beverage

out of the figal tank.

Most Figal tanks have a self-closing valve on the tank as well as the gas and syrup connectors. This allows the operator of the system to change tanks without having to shut down the entire system. With this type of connector, push dow n on the connector while pulling up on the snap ring around the opening of the connector. Then simply pull the connector off the tank.

Operation Checks and Adjustments

ICE DELIVERY SWITCH ADJUSTMENT

To properly adjust the switch, first unplug the power cord to the unit then remove the merchandiser. This will give you access to the ice delivery switch located on the left side of the rocking chute.

Tanks

The stainless steel Figal beverage tanks are easy to store and connect. When using the Figal tanks:

• Use a gas connector for the inlet fitting of the tank.

• Use a syrup connector for the outlet fitting of the tank.

• If more than one Figal tank is connected in series, when changing tanks, remove the tank closest to the original gas inlet while adding the new tank to the connector closest to the syrup outlet.

3-6

Begin by observing the chute by slowly pushing against the rocking chute. When the ice delivery switch clicks, measure the distance from the door stop s on the rocking chute bracket to the door. The distance between the two must be no more than 1/4" (0.64 cm), but no less than 1/16" (0.16 cm).

The left side of the rocking chute has a tab that pu shes up on the ice delivery switch. T o adjust it, use needle nose pliers and bend the arm of the switch up or down in order to change the point where the tab makes contact with the switch arm.
