THEORYOFOPERATION
(see Figure 2)
ACO2cylinderdelivers carbon dioxide (CO2)gasthrough adjustableCO2regulatorstothe product tanks.When
dispensing valveisopened,CO2pressure exerted upon product tank contentspushesproduct fromthe product
tank, through the Unitcooling coil,and on tothe dispensing valveresulting inadispensed drink.
When Unitpowercordisplugged into an electricaloutlet, the compressor,condenserfan motor,and agitator
motorwill startand beginforming an ice bankinthe watertank.When full ice bankhasbeen formed,
compressorand condenserfan motorwill stop butagitatormotorwill continue to operatecirculating icewaterin
watertank.The watertankice bank controlwill cyclecompressorand condenserfan motoron and off as
required tomaintainafull ice bank.
WARNING:CO2displaces oxygen.Strictattention mustbeobservedintheprevention of
CO2(carbon dioxide)gas leaks inthe entireCO2and soft drink system. IfaCO2gas leak is
suspected,particularlyina small area,immediatelyventilatethe contaminatedarea before
attempting torepairtheleak.Personnelexposedto high concentration ofCO2gas will experience
