THEORY OF OPERATION

(see applicable Figure 2 or 3)

WARNING: CO₂dis places oxygen. Strict attention mus t be obs erved in the prevention of

CO₂(carbon dioxide) gas leaks in the entire CO₂and s oft drink s ys tem. If a CO₂gas leak is

s us pected, particularly in a s mall area, immediately ventilate the contaminated area before

attempting to repair the leak. Pers onnel expos ed to high concentration of CO₂gas will experience

tremors which are followed rapidly by los s of cons cious nes s and s uffocation.

NOTE: The s ix-flavor (s ee Figure 3) Unit was s et up at the factory to dis pens e a s till (noncarbonated)

drink from No. 3 dis pens ing valve and carbonated drinks from the remaining dis pens ing valves .

A CO₂cylinder delivers carbon dioxide (CO₂) gas through adjustable CO₂regulators to applicable syrup tanks

or bag-in-box syrup system syrup pumps and to a built-in carbonator located inside the Unit. Plain water is

pumped into the carbonator carbonated water tank by a water pump and is carbonated by regulated CO₂gas

pressure also entering the tank. When a dispensing valve is opened, CO₂gas pressure exerted upon the syrup

tank or on the bag-in-box system syrup pump, pushes syrup through the Unit syrup cooling coils, and on to the

dispensing valve. Carbonated water is pushed by CO₂gas pressure from the carbonated water tank and

passes through the Unit carbonated water cooling coils, and on to the dispensing valve.

Syrup and carbonated water meet simultaneously at the dispensing valve resulting in a carbonated drink being

dispensed. On the six-flavor Unit, a still (noncarbonated) drink is dispensed from the No. 3 dispensing valve in

the same manner as the carbonated drink except plain water is substituted for carbonated water.

The carbonated water tank is replenished when the carbonated water level inside the tank drops, which in turn

automatically starts the carbonator water pump. When the carbonated water level inside the tank has been re-

plenished, the carbonated water pump will stop.

IMPORTANT: TO THE INSTALLER. It is the res pons ibility of the Ins taller to ens ure that the water s upply

to the dis pens ing equipment is provided with protection agains t backflow by an air gap as defined in

ANSI/ASME A112. 1.2-1979; or an approved vacuum breaker or other s uch method as proved effective

by tes t.

Water pipe connections and fixtures directly connected to a potable water s upply s hall be s ized,

ins talled, and maintained according to Federal, State, and Local laws .

CAUTION: Check the minimum flow rate and maximum pres s ure of plain water inlet s upply

line. MINIMUM FLOW RATE MUST BE AT LEAST 100-GALLONS PER HOUR. If flow rate is

les s than 100-gallons per hour, s tarving of carbonator water pump will occur. Starving will

allow water pump to overheat and will damage the pump. Overheating could occur if plain water

inlet s upply line flow rate drops below 100-gallons per hour. CARBONATOR CO₂OPERATING

PRESSURE MUST EXCEED WATER PRESSURE BY 10 PSI. (Example: CO₂operating pres s ure is 80

ps i, maximum water pres s ure can be no more than 70 ps i, etc.) Water over pres s ure (higher than

CO₂operating pres s ure) can caus e carbonator flooding, malfunction, and leakage through

carbonator relief valve. If water is exceeding maximum pres s ure s pecifications , a Water Pres s ure

Regulator Kit (P/N 317589000) or equivalent mus t be ins talled in plain water inlet s upply line.
