
Figure1
Toconnect:
1. SeeFigure1.Checkandcutthetubingendsquarelyandcleanlywithutilityknifeorscissors.
2. Makea½”markattheendofthetubesoyouwillbeabletoconfirmwhenthetubeisinserted
fullyintothefitting.
3. Removethebluelockclipfromthefittingwithyournail.Ifthelocksleevepopsoutofthe
fittingwhendoingthis,simplypopitbackin.
4. Insertthetubeintothefittinguntilyoureachthe½”markonthetube.Youwillfeelresistance
whenthetubereachesthesmallrubberOringinsidethefitting.Youwillneedtowigglethe
tubeandapplyadditionalpressuretogetitpastthisOringandcreatetheseal.Ifthetubeisnot
½”intothefittingandpasttheOring,nosealwillbecreatedandleakingwilloccur.
5. Oncethetubeisfullyinsertedintothefitting,popthebluelockclipbackonthefitting.This
willlockthetubeinplaceandpreventitfrommoving.


Todisconnect:
1. SeeFigures2and3.Removethebluelockclipfromthefitting.
2. Withthebluelockclipremoved,useyourthumbandindexfingertoholddownthelock
sleeve.Thiswillreleasethemetalteethholdingthetubeinplace.Whileholdingthelocksleeve
downwiththathand,useyourotherhandtoremovethetubefromthefitting.

Howtoconnectthecompressionfitting
AcompressionfittingisusedtoconnectthePVCtubingtothethreadedmetalinletwithataperedopen
end,suchastherefrigeratorwaterinlet,drinkingfaucetwaterinlet,etc.

Figure4

1. Slidethebrassnutandtubecollarontothetube.
2. Fullyinsertthetubeinsertintotheendofthetube.
3. Slidethetubecollartowardsthetubeinsertuntilitstops.
4. Insertthetubeintothetapered,openendofthethreadedmetalinletasshowninthepicture.
5. Screwonthebrassnutandtightenitup.Thebrassnutcompressestheplastictubecollaronto
thetaperedmetalsurfaceandcreatesawatersealbetweenthemwhilethetubeinsertstiffens
thetubing.
Howtodrilla½”holeinyoursinkorcountertop
1. It’shighlyrecommendedtowatchtheYouTubevideo“HowToDrillFaucetHoles”togeta
betterunderstandingoftheprocess.Dependingonwhatkindofcountertopyouhave,youmay
wanttohireanexperiencedprofessionaltoensuretheholeisdrilledcorrectly.
2. ChooseahalfinchDiamondCoreBitforgranite,andatitaniumdrillbitforsteel.DoNOTuse
ahammerdrillonnaturestone,glass,andceramic.
3. Anindentshouldbemadewithapunchonsteelbeforedrillingtohelpguidethebit.
4. UsecautionwhendrillingonaPorcelainsink,asitcouldbeeasilychipped.Setdrillspeedon
slow.Pressthebitdownwardfirmlyuntilbreakingthroughtheslipperysurface.
5. Usecoolanttodisperseheat.Choosewaterforgranite,andoilforsteel.UsetheWaterSuction
Cuptoholdcoolantinsideandpreventthedrillbitfromslipping.
6. Startingatslowestspeed,holdthedrillfirmlyandverticallyandpreventthedrillbitfrom
slippingonthecounter.
7. Oncebreakingthroughthesmoothsurface,swirlthedrillalittletoapplypressureinacircle
evenly.
8. Bepatientanddeliberate.Itcantake20–40minutestodrillthroughoneinch.

8.2 TopreventanyresidualcarbonfromthecarbonprefiltersfromgettingintotheROmembrane,
youpreviouslyleftthetubingtotheinletoftheROmembranehousingcapdisconnected.Open
theFeedWaterAdapterValve(AFW)andColdWaterSupplyValve(CWSV),andflushthe

8.3 Oncethewaterisclear,shutofftheAFWandreconnectthetubingtotheROmembrane

ISPRINGROSYSTEMMAINTENANCE
AlliSpringROsystemsaredesignedwitheaseofuseandlowmaintenanceinmind.Ifthefilter
cartridgesarechangedonscheduleassuggestedbelow,thesystemwillworkproperlyforyearsto
come.


Note:Stages6and/or7onlyexistoncertainmodels.Toorderreplacementfiltersforyoursystem,visit
123Filter.comandsearchyoursystem’smodelnumber.
Stage1–3PreFilters
Replaceevery6months,orsoonerifyounoticeadecreaseinwaterfloworquality.
Thereplacementfrequencydependsonyourwaterusageandsourcewaterquality.ToprotecttheRO
membranefromchlorineandotherdamagingcontaminants,itisimportanttochangetheprefilters
accordingtoschedule.
Howtochangethestage1–3prefilters:
1. Shutoffthecoldwatersupplyvalveandtankvalve,andopentheROfaucettodepressurizethe
system.Placeabucketortowelunderthesystemtocatchanywaterspills.
2. Ifthereisenoughroomunderthesinkandthefiltersystemishungonthewall,youcantwist
thefilterhousingoffwithoutremovingthesystemfromthewall.Otherwise,youwillneedto
pullthesystemout,layitdown,andremovethehousingsatthatpoint.Becarefulwiththe
tubingconnectionswhenremovingthesystem.
3. Twistoffthefilterhousingsinacounterclockwisedirectionusingthefilterhousingwrench.
4. RefertoInstallationStep1.1toinstallthenewverticalfiltercartridges,andtightenthefilter
housingsbackon.Remembernottoovertightenthemortheywillbehardtounscrewnext
time.


ChecktheTDSlevelatleastonceamonthtomonitorthesystem’sperformance.TheTDSrejection
rateshouldbe90%+.Tocalculatetherejectionrate,dividetheROwaterTDSintoyourtapwaterTDS
andsubtractfrom1.Forexample,20(ROTDS)/200(TapwaterTDS)=0.110.1=0.9sotheTDS
rejectionratewouldbe90%.(NSF/ASINSTANDARD58forROwaterfilter).


Figure12
1. TheROmembranetypicallylastsabout2–3years.Themembranelifespandependsonthe
sourcewaterquality,yourwaterusage,andhowoftenthethreeprefiltersarereplaced.To
ensurethesystem’sperformanceandwaterpurity,itisimportanttoreplacetheprefilter
cartridgesonschedule.UseaTDSmetertoperiodicallytochecktheROwaterpurity.
2. Shutoffthecoldwatersupplyvalveandtankvalve,andopentheROfaucettodepressurizethe
system.Placeabucketortowelunderthesystemtocatchanywaterspills.
3. Removethetubingfromthequickconnectfittingonthemembranehousingcap.Usethe
membranehousingwrenchtotwistoffthehousingcapinacounterclockwisedirection.
4. Pullouttheoldmembrane.Usescissorsorplierstoapplyleverageifnecessary.
5. Cleanthemembranehousingusinghotwaterandscentfreedishsoap(optional).Rinse
thoroughly.
6. CutopenthesmallendofthevacuumsealedpackagingcontainingthenewROmembrane.
Holdthenewmembranethroughthepackaging,andinsertitintothehousingwithouttouching
themembanewithyourbarehandstoavoidcontaminationofthemembrane.
7. MakesuretheOringisproperlyseatedontheendofthemembranehousingasshowninthe
previousimages.WerecommendreplacingtheOringevery3yearstopreventleakingdueto
anexpiredordriedoutOring.
8. Placethemembranehousingcapbackonandhandtightenit,thenusethehousingwrenchto
