PREPARING FOR OPERATION
1. Fill the bin with 32° F (0.0° C) ice. DO NOT use ice taken directly from a freezer.
2. Make sure that the cold plate has been chilled for at least 1/2 hour prior to setting the ratio (BRIX), per
Pepsi specifications.
3. Start the water booster system according to the suppliers instructions.
4. Turn on the water supply to the unit and pull the relief valve on the carbonator tank, located in bottom of the
unit, to assure that the system is flooded with water and all air is removed.
5. Turn off the water supply.
6. Turn on the CO
2 supply. Supply pressure of 110 PSIG from the bulk or high pressure tank to the secondary
CO
2 guage.
7. Plug the transformer into the electrical outlet. The 24V supply must be connected in the dispensing tower.
The ice-bin lid must be closed to allow the valve to operate.
8. Depress and hold any of the brand buttons that dispense carbonated water until CO
2 only dispenses to
purge the system. Now all air is evacuated and the tank is charged with CO
2.
9. Turn on the water supply to the unit.
10. Plug in the pump deck and the motor will run to fill the carb tank with carbonated water.
11. Start up the BIB pumps according to supplier’s instructions.
12. Press each brand button individually and hold them open to prime the water and syrup lines. It may take
several dispenses until spitting stops and all air has been removed from the water and syrup lines.
13. Set the flow rate for the valve [2-3.75 oz/sec. (59.1-111 cc/sec.)].
DISPENSER VALVE OPERATING PRESSURE
Maximum operating pressure for the valve is 120 PSI (8.27 bar).
CONNECTING PRODUCT TO THE DISPENSER
NOTE: All inlet connections are clearly marked with a label adjacent to the inlet connections. Always leak
check all connections.
Valve must have a supply connected to each inlet. Refer to the plumbing diagram for details of the hook-up.
NOTE: A plumbing diagram, when supplied with the unit, can be found in the dispensing tower.
PROGRAMMING THE VALVES
The valves in the Alta 1522 drop-in dispenser may be programmed for dispensing either carbonated water or plain
water. Before operating the unit, the installer must enter programming mode to select any plain water valve settings
required.
Placing the Valve in Programming Mode
To place the valve in programming mode, press and hold both water buttons and hold them for 5 seconds. This
placed the valve in programming mode and allows the setting of the water type for each brand. When the valve
enters programming mode, the programming LED illuminates. All valves default to carbonated water on entering
programming mode.
To select plain water for a praticular product, the user must press and release the product button. The program LED
flashes twice to indicate acceptance.
After 5 seconds without a button press, the valve exits programming mode and saves the water types in memory.
