 REDlighton(orashing)andpumpwillnotstart:
 1. Startpressuresettohigh.Removeroundcoveroncontrolandadjuststartpressuredial10–15
  psilessthanmaximumboostedpressureasshownonpressuregauge,andpushRESET.This
  unitisfactorysetat50psi.
 2. Watercannotowthroughpumptobuildpressure.Makesureallvalvesareopenandthecheck
  valveisinthecorrectorientation.
 3. Ifinstalledinasuctionliftapplication,primecouldbelost.Re-primeandcheckforleaksonsuction
  side.PushtheRESETbutton,thepumpwillrunfor5seconds,watchpressuregaugetomakesure
  thatthepressureisincreasing.
 4. Makesureallltersareinstalledafterthepump,Changetheltercartridgesregularly.
 5. Thiscanoccurifthewatersupplyhasbeeninterrupted.Thepumpwillautomaticallytryarestart
  15minutesafterafailure.Thiswilloccurautomatically4times,ashingonetimeforeveryfailed
  restart,andthenasolidREDlightwillbeon.
 BLUElightonandpumpwillnotstop:
 1. Pumpstopsonaowratelessthan½GPM.Thisisnormalifowishigher.
 2. Possibleleaksinsystemssuchas;runningtoilets,humidiers,watersofteners,icemakers…
 3. Plasticmagneticpiston(insidebrasscontrol)couldbejammedbyexcessivethreadsealantor
  debris.Loosenunionnutandinspectpiston.Itshouldmovefreelyandspringoutwards(see
  diagrampage4ofinstructionmanual).
 4. Tocheckforwaterleakageinthehouse,closethevalveafterpump.Ifpumpstops,thenwateris
  leakingsomewhereafterthisvalve.Fixleaksandopenvalvesagain.
 5. Ifthepumphasabypassvalveinstalled,makesureitisclosedfornormaloperation(see

 Pumpstartsandstopswithoutobvioususe:
 1. Smallleaksinthesystemcancausethis.ReduceStartPressurebyturningdialtoalower
  pressure.Thenadjustairpressureintank(see#6onpage7ofinstructionmanual).
2. TryalternateFlowModepage8ofinstructionmanual.
 GREENlightonandpumpwillnotstart:
 1. Startpressuredialsetlowerthanincomingpressure.Adjuststartpressuredial10–15psiless
  thanmaximumboostedpressureasshownonpressuregauge,andpushreset.Thenadjustair
  pressureintanksee#6onpage7ofinstructionmanual.
 Pumpstopsatapressurehigherthan80psi.
 1. Thiscanhappenifyourincomingpressureishigherthanthevalueinthetableonpage3of 
  instructionmanual.
  APressurereducingvalveshouldbeinstalledbeforethepump.
 Pumpwillnotstartandnolightsareon.
 1. Makesurepumpispluggedintocontrol,andcontrolispluggedintoaGFCIcircuit.Testwall
  powerreceptaclewithalightormulti-meter.
 2. Testpump.Unplugpowercordfromcontroltopump.Temporallyplugpumpinto  
  extensioncord.Ifpumpruns,unplugandgotostep3.
 3.Unplugpowercordfromcontroltopump.Unpluggraytransducercord.
  TurnStartPressuredialto“0”.Pluginpowercordtocontrol.IftheGreenlight
  comeson,thenreplacethetransducer.Ifnolightscomeon,replacethe
  controlbox.
 IfPumpIsNoisy:
 1.Besurethepumpismountedonasubstantialfoundation.
  Pipeshouldberigidandallconnectionstight.
 2.Totalsuctionliftorowisbeyondthepumpcapabilityandthepumpis
  starvedforwater.
 Pumpwillnotstayprimed(Suctionlift).
 1.Checkfootvalve.Makesureitiscleanandsufcientlysubmerged;
  butisnotinsandormud.
 2.Besurepumpissufcientlyprimed.
 3.Checkforpossibleleaksinsuctionpiping.
 4.Totalsuctionliftmaybebeyondthepumpcapabilityof20feet.
