TYPEOFCHEMICALS—Useonlycommercialgradelow‐energychemicals.Forproperoperation,usenon‐
foamingdetergentsandbufferedsanitizer.Donotwashgold,pewter,silver,orsilver‐platewithchlorine
basedsanitizers.Highconcentrationsofchlorinesanitizersandcausticdetergentswillcausedamagetometals
andwelds.Donotexceed50
parts‐per‐million(PPM)“free”oravailablechlorine.Anysettinghigherthan50
ppmwillbedependentonlocalhealthrequirements,however,theincreasedchlorinewillresultinhigher
corrosionofmetalparts.Purpose‐builtware‐washingdispensersareneededtoproperlymeterchemicalsfor
washandrinse.Thesedispensersareincludedwiththismodel.Manuallyaddingindustrialchemicalstothe
dishmachineisunsafeandnotapproved.

CHEMICALLINES—Placecolorcodedtubesintoproperchemicalcontainers.Thecontainersneedtobeas
closetothemachineaspossibleandatfloorlevel.Thismayrequireshorteningoftheflexiblechemical
transfertubes.Onthesideofthecontrolboxdoor,therearechemicalprimeswitches.Thereisadecal
identifyingeachswitch.Toprimechemicals,usethesemomentaryprimeswitches,verifyingthatallthree
pumpsrotate.Ifachemicalpumpsqueezetubehastakenaset(notallowingthepumptoturn),manuallyfree
