CO2 PULSE VALVE REPLACEMENT
The CO2 valves, shown in Figure 46, are located near the center of the unit and
are mounted on a bracket to the bottom of the chassis. They control the injection
of CO
2 with the syrup/water combination to provide the final mixture for the prod-
uct. There are one of these solenoids for each barrel in the system. When working
in this area, care should be taken not to damage or misalign the CO
2 metering
orfice. To replace one of these valves, perform the procedure in Table 48.
