FIGURE 1. SENTRY III-A COOLING UNIT THEORY OF OPERATION (see Figure 2) A CO cylinder delivers carbon dioxide gas (CO ) through adjustable CO regulators to the soft drink tanks and 2 2 2 also to the built--in carbonator located inside the Cooling Unit. Plain water is pumped into the carbonated water tank by the water pump and is carbonated by regulated CO pressure also entering the tank. When dispensing 2 valve is opened, CO pressure exerted upon the syrup in the soft drink tank pushes syrup from
