OptimizingYourCleaner
Cleaning- checkthetankforcontaminationwheneveryouchange
solution. Ifnecessary,removecontaminantswitha nonabrasivecloth
andwater.
Emptying- alwaysunplugthecleanerbeforeemptyingthetank.Empty
thesolutionintoa wastedisposalunit.
Filling- alwaysunplugthelinecordbeforefillingthetank.Fillthe
cleanertotheoperatinglevel(oneinchfromthetopwithbeaker/trayin
place),usingwarmtapwater.
Lowsolutionlevel- willcausethecleanerto fail. Whenyouremove
heavyorbulkyloadsfromthecleaner,thesolutionlevelmaydropbelow

necessary,dependingontheamountused.

Instead, usea trayand/orbeakerpositioningcovertosupportallitems.
Allowatleastoneinchbetweenthetankbottomandthebeakeror

Covers- allowthecleanertoheatupfaster,toa highertemperature,
andlimitexcessiveliquidevaporation.However,leavingthecoveron
withheatandultrasonicsoperatingcancausethesolutiontobecome
veryhot,diminishingeffectivenessandcreatingthepotentialforburns.
Heater- theheatermaycausesomediscolorationofthetank wall. This
isnormalandwillnotaffecttheperformanceoftheunit.
Solutiontemperature-thefastestmethodtoheatyourcleaneristofill
withwarmsolution,useheat,ultrasonics(whichalsoaddsheat),anda
