Installing the Pump Tubing

DischargeSide(tubingthatfeedsfromtopofpumpintopipewherethewateristobechlorinated)
1. Shutoffwellpumporwatersupplyandde‐pressurizepipe.
2. Installinjectioncheckvalvebyinstallingapipeteeinyourpipethathasa½”NPTfitting,whereyoucanscrewin
theinjectioncheckvalve(includedwithyourPrecision‐24pump).WraptwowrapsofTeflontapeonthe½”pipe
threadsoftheinjectioncheckvalveandapplyalightcoatingofTeflonwhitepipepasteandinstallintopipes.
3. Installtubingthatcamewithyourpumpandconnectpumptoinjectioncheckvalve.
4. Cutleadtubetodesiredlengthwithenoughslacktoavoidkinks.Handtightenonly.DonotuseTeflontapeon
thetubingfittingconnections.
DegassingPrimeValve(tubingthatallowsthesolutiontobepumpedbackintothetankforfastpriming)
1. Connectthe3/4"tubingsuppliedtothedegassingprimevalvetothesolutiontankbydrillingaholeasshownon
Page6.
2. Insertandtrimthetubingsoitinsertsintothesolutiontankafewinches,butdoesnottouchthesolution.


Whenattachingthetubing,makesuretopushthe
tubingallthewaytotheend,sothatitisupagainst
thebarbedcompressionfitting.Tryheatingtheend
ofthetubingbydippingitinacupofhotwateror
pressingitupagainstahardsurfaceifyouare
havingtroublegettingittotheend.

Page9Precision‐24PumpChlorinationSystemInstallationGuideRev62416CleanWaterSystems2016
SuctionSide(tubinginsidesolutiontank)
1. Measuretheleadtubeonoutsideofsolutiontanktoensureitwillbe2‐3”fromthebottomofthetank.Donot
allowweighttositatthebottomofthetank.
2. Runtheleadtubetothesolutiontank.Allowforsomeslackinthetubetoavoidkinks.
3. Addtheweight,andconnectthenutferruletothesuctionsideofthepumpinghead(labeled‘in’oncoverof
head).Handtightenonly.DonotuseTeflontape.
4. MakesurethatthetubingisFULLYinsertedovertheconicalshapedfitting,sothatittotallybottomsoutandis
pressedupagainstthefitting.Ifitisdifficulttopushtheendofthetubingtothebottomofthefitting,try
heatingthetubingwithwaterorhotair(suchasahairdryer).Thetubingcanthenbeworkedalittlebackand
forthandworkeddownuntilitisseated.Thenproceedbyputtingthefittingonandtighten.
Prime&StartThePump:
1. Fillsolutiontankwith7gallonsofcleanwater(don’taddchlorinebleachyet),thiswillmakeiteasiertoprime
thefillthesuctiontubingwithwater.
2. Fillsuctiontubingwithwater,bysubmersingthesuctionendinthewaterandrapidlyjerkingthesuctiontubing
upanddown.Withinafewmoments,thesuctiontubingwillbefullofwater.Keepingtheopenendatalower
elevationwillprimeitfaster.Thesuctiontubingcan
alsobesubmergedorfilledwithwatermanually.This
makesitfastertoprime.(Pictureonright)
3. Connectthesuctiontubinganddischargetubingto
yourinjectioncheckvalve.
4. Connectthedegassingprimevalvetubingandrouteto
thesolutiontank,abovethewaterline.
5. Openupthedegassingprimevalvethreeturns
counter‐clock‐wisetoopenitupbeforepriming.There
maybebackpressureonthepump,soitwillbeeasier
toprimeifthedegassingvalveisopenatfirst
6. TurnonthepumpandadjusttheStrokeKnobto100%
andSpeedcontrolto100%.
7. Youwillquicklyseewaterbeingpumpedoutthedischargetube.
8. Afterthepumpisprimedandispumping,closethedegassingvalve2‐1/2turns.Thelittlevalveshouldbejust
slightlyopen,soasmallamountofchlorinesolutioncanbepumpedbackintothetank,whenthepumpis
running.
9. Yourpumpisnowreadyforuse!
10. Afterthepumphasbeeninoperationforanhourorso,youshouldre‐torquetheliquidendofthepump(back
end)andre‐tightenthescrewsontheheadinacriss‐crossfashion.
11. Add1gallonofchlorineto7gallonsofwater,orfollowyourownsolutionstrengthandspeedsettingsby
consultingtheformulabelow.

AdjustingtheMeteringPumpSettings:
HowToSelecttheChlorineSolutionStrengthandPumpSetting
Thegoalofaproperlyfunctioningchlorineinjectionsystemistohaveafree‐chlorineresidualof0.2to1.0ppmafter
sufficientcontacttime,beforeanycarbonfiltersystem.Orifnocarbonfilterorotherde‐chlorinationisused,tohave
afree‐chlorineresidualof0.2to1.0ppmattheendofthedistributionsystemorfurthestpointintheplumbing.
ThiscanbeaccomplishedbyadjustingthechlorinebleachsolutionstrengthandsettingthePrecision‐24StrokeKnob
and/oradjustingthespeedsettinguntilyouachievethedesiredresidual.

Indeterminingyourmeteringpump’ssettingsandsolutionstrength,keepinmindthatit’sbesttomakeupfresh
solutiononceevery1to3months.Thechlorinesolutionlosesstrengthasitages,andissensitivetoheatandlight.
Generally,keepsolutiontankoutofthesunandusefreshsolutionregularlyforbestresults.

StepOne:Determineflowrateofthewaterstreamyouareinjectinginto,inGallonsPerMinute(GPM)
1.Openanyhosebiborfaucetuntilpumpturnson.
2.Closehosebiborfaucetandletpumpfilluppressuretankuntilitturnsoff.
3.Usinga1or5gal.bucket,openfaucet,collectandmeasureallwaterdischargeduntilpumpturnson.
4.Whenpumpturnson,immediatelyclosefaucetandstarttimingpumpcycle.
5.Whenpumpturnsoff,recordpumpcycletimetorefillpressuretankinseconds.
6.DividethenumberofgallonscollectedinStep3bythenumberofsecondsinStep5.
7.MultiplytheanswerfromStep6by60.
8.TheanswerinStep7istheaveragepumpingcapacityofthepumpingallonsperminute(GPM).

StepTwo:HowMuchChlorineShouldBeInjected?Determinethepartspermillionofchlorineyouaretryingto
achieveinpartspermillion(PPM).

Chlorineisinjectedinpartspermillion('ppm')whichisthesameassayingmilligramsperliter('mg/L').Theamountof
chlorinetoadddependsonthe“chlorinedemand”ofthewater.Chlorinedemandistheamountofvarious
contaminantsinthewaterthatcombinewiththechlorineafterthechlorinehasbeeninjectedandsufficientcontact
