PERATION
NOTE: THE UNIT IS FACTORY SET TO DISPENSE NON-CARBONATED
WATER AND CARBONATED WATER AS PER CUSTOMER'S REQUIRE-
MENT. IT IS AVAILABLE TO DISPENSE AT MOST 3 NON-CARBONATED
WATERS WITH CARBONATED WATER DISPENSING FROM THE REMAIN-
ING VALVE(S). NON-CARBONATED WATER DISPENSING VALVE(S) MAY
BE CONVERTED TO ALSO DISPENSE CARBONATED DRINK(S).
A CO
cylinder delivers carbon dioxide (CO
) gas through adjustable CO
2
2
2
regulators to the applicable syrup tanks or bag-in-box syrup pumps and also
the integral (built-in) carbonator. Plain water enters the integral carbonator
carbonated water tank and is carbonated by CO
gas pressure also entering
2
the water tank. When dispensing valve is opened, CO
gas pressure exerted
2
upon the applicable syrup tank contents or bag-in-box syrup pump pushes
syrup from the syrup supply, through the Unit syrup cooling coil, and on to the
dispensing valve.
Carbonated water is pushed from the integral carbonator carbonated water
tank by CO
gas head pressure and is pushed through the carbonated water
2
manifold to the dispensing valve. Syrup and carbonated water meet simultane-
ously at the dispensing valve resulting in a carbonated drink being dispensed.
A still (non-carbonated) drink is dispensed in the same manner as the carbon-
ated drink except plain water is substituted for carbonated water.
