DESCRIPTION
IMPORTANT:To theuserof thismanual-Thismanual isaguideforinstalling,operating,and
maintaining this equipment.RefertotheTableofContentsforpagelocation fordetailedinformation
pertaining to questionsthatarise during installation,operation,service,ormaintenance of this
equipment.
CAUTION:Before shipping,storing,or relocating thisUnit,the syrup systemsmustbe
sanitizedand all sanitizing solution mustbepurgedfromthe syrup systems.All watermust
also bepurgedfromtheplainand carbonatedwatersystems.Afreezing ambient
environmentwill cause residualwaterintheUnit tofreezeresulting in damagetointernal
components.
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

The SentryIII-A Post--MixCooling UnitwithR-134ARefrigerant(see Figure 1)isdesigned to provide cooled
syrup,carbonated water,and plainwatertothe dispensing station(s)connected tothe cooling unit through an
insulated python (length asordered).
The lowercabinetof the Cooling Unitconsistofcarbonated water,plainwater,and syrup coilslocated inthe
watertank,acarbonator,and a carbonated watercirculating pump.The Cooling Unitutilizesa drop--inrefrigera-
tion assemblywhichcontainsthe refrigeration compressorand a condensercoil and fan assemblyas shownin
Figure 3
An optionalCooling UnitStand (P/N309802069)isavailableto elevatethe Cooling Unitup off the floor.

THEORYOFOPERATION
(see Figure 2)
ACO2cylinderdelivers carbon dioxide gas(CO2)through adjustableCO2regulatorstothe soft drinktanks and
alsotothe built--incarbonatorlocated inside the Cooling Unit. Plainwaterispumped intothe carbonated water
tankbythe waterpump and is carbonated byregulated CO2pressure also entering the tank.When dispensing
valveisopened,CO2pressure exerted upon the syrup inthe soft drinktankpushes syrup fromthe tank,
through the Cooling Unitcooling coils, through the python and on tothe dispensing valve.Carbonated wateris
pushed byCO2pressurefromthe carbonated watertank, through the Cooling Unitcooling coils, through the
python and on tothe dispensing valve.Syrup and carbonated watermeetat the dispensing valveresulting in a
carbonated drinkbeing dispensed.Plainwaterisalso available at the dispensing station bypassing through the
Cooling Unitcooling coils, through the python,and on tothe dispensing station.Carbonated waterisreplen-
ished when carbonated waterlevel inside the carbonatortankdropstoaspecified levelwhichinturn automati-
cally startsthe carbonatorwaterpumpmotor.When carbonated waterlevel inside the carbonated watertank
hasbeen replenished,carbonatorwaterpumpmotorwill stop.Carbonated wateris continuouslybeing circu-
lated fromthe Cooling Unit, out through the insulated python tothe dispensing station(s),and back tothe cool-
ing unitwhichmaintainsliquidsinthe python atacoldtemperature.
