Note
Allplumbingworkmustbeperformedbyaqualiedtechnician.Alwaysfollowalllocal,stateand
provincialcodes.
Aproperinstallationrequiresapressurereliefvalve,a¼"femaleN.P.T.threadedttingforthepressuresensor,
andproperlysizedpipe.Pipingshouldbenosmallerthanthepumpdischargeand/orsuctionconnections.
Pipingshouldbekeptasshortaspossible.Avoidtheuseofunnecessaryttingstominimizefrictionlosses.
Somepumpandmotorcombinationssuppliedwiththissystemcancreatedangerouspressure.
Selectpipeandttingsaccordinglyperyourpipesuppliers’recommendation.Consultlocalcodes
forpipingrequirementsinyourarea.
Alljointsmustbeairtight.UseTeontapeoranothertypeofpipesealanttosealthreadedconnections.Please
becarefulwhenusingthreadsealantasanyexcessthatgetsinsidethepipemayplugthepressuresensor.
Galvanizedttingsorpipeshouldneverbeconnecteddirectlytothestainlesssteeldischargeheadorcasingas
galvaniccorrosionmayoccur.Barbtypeconnectorsshouldalwaysbedoubleclamped.
Pressure Tank, Pressure Relief Valve and Discharge Piping
Useonly“pre-charged”tanksonthissystem.Donotusegalvanizedtanks.Selectanareathatisalwaysabove
34ºF(1.1ºC)inwhichtoinstallthetank,pressuresensorandpressurereliefvalve.Ifthisisanareawherea
waterleakorpressurereliefvalveblow-offmaydamageproperty,connectadrainlinetothepressurerelief
valve.Run the drain line from the pressure relief valve to a suitable drain or to an area where water
will not damage property.
Pressure Tank, System Pressure
Sizing–Abladdertank(notincluded)isusedtocushionthepressuresystemduringstart-upandshut-down.It
shouldbesizedtoatleast20%ofthetotalcapacityofyourpump.Example:Ifyourpumpissizedfor100GPM
thensizeyourtankforatleast20gal.totalvolume,notdrawdown.Pre-chargeyourbladdertankto10-15PSI
belowyoursystempressure.Thecontrollerispre-setfor50PSIatthefactory.Thereforea35-40PSIpre-charge
inyourtankwouldberequired.Usethehighertankpre-chargesettingifthesystemdriftsover5PSIata
constantowrate.NOTE:Pre-chargeyourtankbeforellingwithwater!
Caution
MaximumworkingpressureofHydroProbladdertankis125psi.
Installing the Pressure Sensor
Thepressuresensorrequiresa¼"FNPTttingforinstallation.Installthepressuresensorwiththeelectrical
connectorpointinguptoavoidcloggingthepressureportwithdebris.Installthepressuresensorinastraight
runofpipeawayfromelbowsorturbulence.Foroptimumpressurecontrolinstallthepressuresensorinthe
samestraightrunofpipeasthepressuretank.Ensurethepressuresensoriswithin10ftofthepressuretank.
Installingthepressuresensorfarawayfromthepressuretankmayresultinpressureoscillations.Do not
install the pressure sensor in a location where freezing can occur.Afrozenpipecancausedamagetothe
pressuresensor.
