chemicalproducts.Alwaysusechemicalresistantsafetyglovesandsafetygoggles(indirect‐ventedornon‐

AnymodificationstothechemicaldeliverysystemforsmallercontainersmustincludeClosedLoopChemical

CHEMICALADJUSTMENT—Chemicaldispensingiscontrolledbyamechanicalcamtimer.Allchemicalproducts
mustbeadjustedfortheproduct’sconcentrationandlocalwaterconditions.Itwillbenecessarytoadjust
initialfactorysettings(SeebelowforCamTimerAdjustmentSection).Watersoftenersshouldbeaddedto
correcthardwaterconditions.Hardwaterisoftentreatedwithmoreexpensiveware‐washingchemicals,but
itismoreeffectiveandlessdestructivetothemetaltosoftenthewaterbeforeitcomestothedishmachine.

AUDIBLECHEMICALALARMOPTION—Theoptionalchemicalalarm(P/N031‐0326)usesapressureswitchwith
abarbfittingthatextendsfromthecontrolboxandconnectstothechemicallinebymeansofa“t”fitting.
Theswitchsendsvoltagetoabuzzerlocatedinthecontrolbox.SensitivityisadjustedbyanAllenwrench
(5/64”or2mm)toturnascrewlocatedinthecenterofthebarb(seephotoabove*).Removethetubefromthe
barb;turnthescrewtotherightforlesssensitivity.Chemicalbucketsmustbeplacedonthefloorforthe
