THEORY OF OPERATION
WARNING: CO
2
displaces oxygen. Strict attention must be observed in the prevention of
CO
2
(carbon dioxide) gas leaks in the entire CO
2
and soft drink system. If a CO
2
gas leak is
suspected, particularly in a small area, immediately ventilate the contaminated area before
attempting to repair the leak. Personnel exposed to high concentration of CO
2
gas will experience
tremors which are followed rapidly by loss of consciousness and suffocation.
CARBONATED UNITS
Standard Units (Requires Connection To a Remote Carbonator).
(see Figure 2)
The Unit was set up at the factory to dispense a still (non-carbonated) drink from No. 3 dispensing valve and
carbonated drinks from the remaining dispensing valves. No. 3 dispensing valve may be converted to also dis-
pense a carbonated drink. Refer to TABLE OF CONTENTS for conversion instructions.
A CO
2
cylinder delivers carbon dioxide (CO
2
) gas through adjustable CO
2
regulators to the applicable syrup
tanks or bag-in-box syrup pumps and also to a remote carbonator. Plain water enters the remote carbonator
carbonated water tank and is carbonated by regulated CO
2
gas pressure also entering the tank.When dispens-
ing valve is opened, CO
2
gas pressure exerted upon the syrup tank or on the bag-in-box system syrup pump,
pushes syrup through the Unit syrup cooling coil, and on to the dispensing valve.
Carbonated water is propelled by CO
2
gas pressure which pushes carbonated water from the carbonated water
tank, through the Unit cooling coils, and on to the dispensing valve. Syrup and carbonated water meet simulta-
neously at the dispensing valve resulting in a carbonated drink being dispensed. A still (non-carbonated) drink is
dispensed from No. 3 dispensing valve in the same manner as the carbonated drink except plain water is substi-
tuted for carbonated water.
