
Pre‐Installation
1. Reviewyourpackinglistandmakesureyouhavereceivedallthepartsbeforebeginning
installation.
2. Ifyouaregoingtobeturningoffthewatertothehouseandyouhaveanelectricwaterheater,
shutoffthepowertothewaterheaterbeforebeginninginstallationincasewaterheateris
accidentallydrained.
3. Pickasuitablelocationforyourfiltersystemonadrylevelspotwhereitwon’tbeexposedto
freezingtemperatures.Aminimumof20PSIisrequired.Maximumpressureis90PSI.
4. Getallofyourplumbingpartstogetherbeforebeginninginstallation,andmakesureyouhave
receivedallofyourpackagesbeforebeginningorschedulinganinstallation.Installationtypically
takes3to5hours.However,afterinstallationtheGreensandFiltermustbeallowedtorun
throughacompletebackwashandrinsecycle.
5. Afterthesystemisinstalledandrunning,yourwatermaybediscolored,orfullofsedimentor
rust,particularlyifthisisolderorcorrodedpiping.Thistypicallyclearsupoveradayortwo.
BestPracticesforPiping&DrainInstallation
1. Seetypicalinstallationonpage7(Fig2).TheGreensandfilterisinstalledafterthepressure
tank.
2. MakesuretoconnecttheInletfromyourwatersource.MakesuretoconnecttheOutletto
wherethewaterisbeingusedandbesureandinstalltheExternalFlowControlfittingontothe

7500Pro‐OxFilterInstallation&StartupGuide
Page5www.cleanwaterstore.comRev060116
DrainPort.FromthemalepipethreadontheExternalFlowfitting,youcantransitiontoabarb
fittingandruntubingtowhereyouneedto.
3. Makesurethereisaworkinggateorballvalvebeforethe7500GreensandFilterandalsoone
afterasshowninFig2.Thepressuregaugesareoptional,buttheyareagreatwaytotellata
glanceifyourfilterneedstobebackwashed.Ahosebib(whichisafaucettowhichyoucan
attachagardenhose)isstronglyrecommendedaftertheGreensandFilterandbeforethe
secondballvalve.ThismakesiteasytorinseyournewGreensandFilteronstart‐upandgives
youaplacetotestthewaterbeforeitentersyourhouseholdplumbing.
4. Ifyouwillbeusingcopperpiping,donotsweatthecopperpipedirectlyontothe7500control
valve.Avoidheatingupthe7500controlvalveplasticwiththetorch.
5. Youshouldinstallunionsandabypassaroundthevalve,sothatyoucanremoveitandstillhave
water.
6. Thedrainlinetubing(notsupplied)isconnectedtoadrainfromtheExternalFlowControlfitting
usingaFemaleXBarbedfittingandflexibletubing.Notethatthedraincanrunupabovethe
7500controlheadandintoadrain,itdoesnothavetodraindown,asthefilterbackwashes
underlinepressurefromyourwellpump.Mostplumbingcodesrequireanair‐gapconnection,
sothatifyoursewerorseptictankbacksup,itcannotcrossconnectwiththedraintubing.



HowYourGreensandFilterWorksSeeFig1ontheright.
InyourGreensandFilterthewaterentersthetopofthetank(red
arrows)andflowsdownthroughthemediaandupthedistributor
tube(bluearrows).ThedownflowtypeGreensandFilterremoves
ironandcanbebackwashed,whichcleansandre‐classifiesthe
media,preventingchanneling.Duringbackwashtheflowofwateris
reversedandwaterflowsdownthedistributortubeandupthrough
themedia,liftingandexpandingtheGreensandmedia.Duringthe
backwashthemediaiscleanedbytheactionofthewaterflowing

AssemblyandInstallationInstructions
1. Wrapthetopofdistributortubewithblackelectricaltapeorbluepainter’smaskingtapesothat
nogravelorGreensandmediawillgodownthedistributortubewhenaddingthemedia.Also,
leavingafoldedtaboftapethatyouwillbeabletograbontotogentlypulloffthetapeafter
fillingthetank.Whenyouarereadytoscrewthevalveheadon,applysiliconelubricanttothe
outsideofthedistributiontube,andtheo‐ringonthecontrolvalvewherethetubegoesin.






2. Addthefiltergravelthatcamewithyourorder.Youwantthegraveltocoverthebottom
distributorscreenbeforeaddingtheGreensandmedia.
3. NextaddGreensandmedia.Thetankshouldbeabout2/3rdsfullofmedia,donotfillmorethan
2/3rds,evenifthereissomemedialeftover.
4. Removetapefromtopofdistributortube.Becarefulnottopullupdistributortubewhen
removingtape.
5. Add1cuphouseholdbleachtoinsidedistributortubeandfillGreensandFilterwithwater.This
willallowtheGreensandFiltermediatosettleandeliminatetheneedof“purging”theairoutof
thetanklater.Letchlorinewatersolutionsoakfor1–2hoursbeforebackwashingandrinsing.
6. Attachplastictopscreentotheunder‐sideofthe7500controlvalve.Itisafunnel‐shaped
plasticscreenthatsnapsontothecontrolvalveandpreventsresinfrombeingbackwashedout
todrainduringtheregenerationcycles.Itmaytwistonclockwiseorcounter‐clockwise.




7. Screwon7500controlvalvecarefully.Donotusepipe‐jointcompound,vegetableoil,Teflon
tape,orVaselineorotherpetroleumgreasestolubricatetankthreads.

InitialBackwash:
Beforetheunitcanbeputintoservice,acoupleofbackwashcyclesmustbedone.Thisisfor:
Rinsingthedustoffthemedia
Removemedia“fines”(bitsofbrokenmediasosmalltheypassthroughthescreen)
Testsystemforplumbingleaks/failures.
YouwillstartthefirstbackwashwiththeInletandOutletvalvesclosed.
1) FromtheServiceMode(DynamicDisplayStripeisshowing),presstheManual/Returnbutton.
Thiswilladvancethevalvetothebackwashposition(redicon,threearrowspointingdown).
2) OpentheInletvalvejustenoughsothatyoucanhearwatergoingthrough.Afterafewseconds,
asmallamountofwaterwillstartcomingoutofthedrainline.Thevalveiscountingdown,
fromtenminutes.
3) Openthevalvealittlemore;youwillseeanincreaseintheflowcomingoutofthedrainline.
Eachtimeyouopenthevalve,youarelookingforbubblesandforthewatertoturnblackfora

HowToRemoveMediaFromControlHead
Sometimes,whendoingtheInitialBackwash,themediagetsliftedupintothecontrolhead.Youcantell
thishappenedbecauseyouwillhavelittleornoflow,eithergoingouttodrainwhileinthebackwash
positon,orwhenintheservicepositon.
Toremovemediafromacontrolhead,dothefollowing:
1)PuttheInletBypassintheClosedposition.
2)FromtheServiceMode,initiateamanualregeneration,bypressingandholdingtheregenbutton
(buttononfarleft).
3)ThevalvewilladvancetotheBW(backwash)position,andstartcountingdown.PresstheRegen
buttonagain,andwaitforthevalvetoadvanceandstopattheRapidRinse(RR)position.
4)WiththevalveintheRRposition,openandclosetheInletBypassvalveseveraltimes.Afterthethird
orfourthtime,leaveitintheopenpositionandcheckthedrainline‐doyouhaveagoodsolidflow?
90%ofthetime,theanswerisyes,butsometimes,evenafteropeningandclosingthevalvemanytimes,
youstilldon’thavegoodflow…But,ineithercase(goodornoflow),continue…
5)WiththeInletValveOFF,AdvancethevalvebacktoServicepositionagain,andagainpressandhold
theRegenbutton,weareputtingthevalvebacktotheBackwashposition.

6)OpentheInletvalvejustenoughsoyoucanhearthewaterpassingthruthevalve‐youshouldnotice
acorrespondingslowflowoutofthedrainline.Afteraminute,iftherearenoairbubblespresent,open
thevalveaboutanotherquarterinch‐again,youshouldseeacorrespondingincreaseintheflow…And
youwillcontinueuntilthevalveisfullopen.
IMPORTANT:
AnytimethatyouareintheBackwashorRapidRinseposition,youmayneedtounplugthepower‐this
willholdthevalveinitscurrentposition,soitdoesn’t‘timeout’andgotothenextposition.Whenyou
plugthevalvebackin,afteraminuteitwillreturntowhereitwaswhenyouunpluggedit(i.e.2:32
remaininginBW).Understand,itisnotpossibletojammediaintotheheadwhileinRapidRinse,or
Service,justintheBackwash,whentheflowdirectionisreversed.
Whatyouaretryingtoaccomplish,afteryouhavepushedthemediabackintothetankintheRapid
Rinseposition,istogettheInletvalveallthewayopenintheBackwashposition,withoutitjamming
mediabackinthehead,andthisisthepartwhereyouhavetogoslow,openuptheInletvalvealittle
bitatatimeandletitrunforafewminutes‐thisiswhyyoumayhavetounplugit‐andthen,onceyou
havedonethat,finally,doonemorebackwash,startingwiththeInletvalveopen,justasitwillbewhen
itdoesitautomaticallyatnight.Onceitdoesthatsuccessfully,youaredone.
