ForADSfamilymodelsofET‐AFandthemodelASQ,thechemicalFlowIndicator(084‐6403)isthevisual
meanstoindicateliquidisflowinginthefeedersystemfordetergentandsanitizer.Ineachofthetubes
machinedthroughtheclearplastichousing,thereisablackcoloredmarble(099‐1008).Squeezetube
material(092‐2000)isinsertedinbothupperandlowertubeopenings.Thesetubesarepushedintotheholes
ofthehousingandheldinplacebytensionofthetubewallagainst
thehousing’sinnersurface.When
insertingthesqueezetubesintothehousing,lubricationusingdishsoapishelpful.

Whenthetoptubeoftheindicatorisconnectedtotheinletsideofthechemicalperistalticpump,liquidis
drawnupthroughthesupplytubeofthechemicalbucket.Theliquid
isdrawnintothebottomoftheFlow
Indicatorhousingandliftstheblackindicatormarbleupwardinthevisualchamber.Thismovementshows
flowoftheliquidinthetube.Thetubewithredcoloredliquidwillindicatedetergentflowing,thetubewith
clearliquidwillindicatesanitizer(chlorine)flowing.
Theoperatorshouldbeinformedthatthismovementofthemarblesinthehousingisthevisualindication
thatchemicalsarebeingdeliveredforthewashingandsanitizingoperationsofthedishmachine.
Managementshouldbenotifiedifthereisnomovementoftheindicators.
