OPERATION
1. CO
2
cylinder - Holds highly pressurized carbon
dioxide (CO
2
). The CO
2
cylinder is a steel or alu-
minum cylinder tank. CO
2
gas flows to the primary
pressure regulator.
2. Primary pressure regulator - Lowers the CO
2
gas
pressure, usually to 100 psi.
3. Lowered outgoing pressure gauge - Gauge indi-
cates lowered outgoing pressure from the CO
2
cyl-
inder after being routed through the primary pres-
sure regulator.
At a T-fitting, this line then forms two branches: One
branch feeds CO
2
gas to the carbonator tank and the
other branch feeds CO
2
gas to the Figal tanks.
Pumping Syrup to the Dispenser:
4. Secondary pressure regulator - Lowers the CO
2
gas pressure, usually at 45-60 psi, before the CO
2
gas flows to the Figal syrup tank. Diet syrup is usu-
ally 10-15 psi.
5. Syrup pump - Syrup flows through the syrup lines
to the dispenser for chilling, then dispensing.
6. Figal tanks - Steel tank which usually holds five
gallons of syrup. Several Figal tanks supply the
dispenser.
