An overall schematic of the three delivery systems contained in the unit are 
shown in Figure 5. The CO
2
 system is on top, the water system is in the middle 
and the syrup system is at the bottom of the diagram. The CO
2
 system interacts 
with both the water and syrup systems. It provides pressure and carbonation for 
the syrup/water product mix.
CO
2
 System
A CO
2
 tank or bulk CO
2
 supply delivers carbon dioxide gas (CO
2
) to an adjust-
able secondary CO
2
 regulator assembly that is attached to the tank as shown in 
2
 system also supplies CO
2
 to the water boost 
pump, the expansion tank regulator and the secondary CO
2
 tank regulators.
CO
2
 enters the expansion tank regulator and is reduced to approximately 30 
psig to feed holding pressure on the expansion tank. This provides a force to 
work against the barrel pressure when the product freezes and expands.
CO
2
 also enters the secondary regulators. These regulators are used to adjust 
barrel overrun/expansion for various products. The pressure settings for various 
types of syrup are shown in Table 1. Overrun CO
2
 pressure is applied to the CO
2
 
control solenoids through preset orifices and on to the in-line check valves.
From the in-line check valve, the CO
2
 flows into the product line.
