An overall schematic of the three delivery systems contained in the unit are shown
in Figure 9, Figure 10 and Figure 11. The CO
is in the middle and the syrup system is at the bottom of the diagram. The CO
system interacts with both the water and syrup systems. It provides pressure and
carbonation for the syrup/water product mix.
A CO tank or bulk CO supply delivers carbon dioxide gas (CO
2 2
secondary CO regulator assembly that is attached to the tank as shown in Figure

7 and Figure 8. The CO system also supplies CO
2
expansion tank regulator and the secondary CO
CO enters the expansion tank regulator and is reduced to approximately 30 psig
2
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 also enters the secondary regulators. These regulators are used to adjust
2
barrel overrun/expansion for various products. The pressure settings for various
types of syrup are shown in Table 1. Overrun CO
control solenoids through preset orifices and on to the in-line check valves.
From the in-line check valve, the CO
