     thepump.
   •Primingthepumpiseasierifitisatequalorlowerheight

     oncethepumpbeginstoprime.Note: A hose can be
attached to the hose barb and run back to the water
supply if desired.

Priming Tips:
 A. Whenprimingthepumpfromanon-pressurizedsupply,
   itisrecommendedtolltheinputgardenhosebefore
   turningonthepump.
 B. Theinputttingforthepumpisastandardgardenhose
   connection.Whenthisattachmentismadeitisimportant
   tomakesurethegardenhoseistightenedsnugglysothat
   thepumpdoesnotsuckairthroughtheloseconnection.
   Alooseconnectionwillmakethepumphardtoprime.
 C. Theshorterthegardenhose,theeasieritistoprimethe
   pump.Longhosestendtocollapsefromthesuctionofthe
   pumpwhendrawingfromanon-pressurizedsystem,
   restrictingow.
 D. Useahosethatisrigidenoughsothatitdoesnotcollapse,
   especiallywhendrawingwaterfromanon-pressurized 
   system.
2. Connect the High Pressure Hose to the system being
checked.
 A. Ifthesupplywateriscomingfromapressurizedsystem,
   itisrecommendedtollthesystemtobetestedwithwater
   priortoturningonthepump.Thiscanbedonesimplyby
   openingtheOutletvalveonthepump,allowingwaterto
   owthroughthepumpandhigh-pressurehoseintothe
   systembeingtested.Oncethesystemllsandpressure
   beginstorise,proceedtothenextstep.
 B. Non-pressurizedsystemsshouldbelledwithwaterpriorto
   attachingthehigh-pressurehoseandturningonthepump,
   ifatallpossible.Thiscouldspeedupthetestingprocess.
 C. Theoutputttingattheendofthehigh-pressurehoseis
   3/8”NPT.Anadaptormaybeusedtoattachthishoseto
   thesystemthatisbeingpressuretested.
3. Plug in the cord and turn on the pump to pressurize the
system to the desired test pressure.
 A. Pressurecanbeadjustedbyturningthepressure
   adjustmentknobonthesideofthepump.Turning
   clockwisewillincreasethepressure.Turningcounter- 
   clockwisewilldecreasethepressure.
4. Once the system reaches the desired pressure, close the
outlet valve and turn off the pump.
 A. Oncethepumpreachesthesetpressureitwillcontinue
   torunbutthewaterwillowthroughtheAutomatic
   Bypassandrecirculatethroughthepump.Itisnot
   recommendedtorunthepumpinbypassmodeformore
   thanacoupleofminutes.Oncethedesiredpressureis 
   reached,itisunnecessarytocontinuerunningthepump.
   Closethevalve,turnoffthepumpandunplugthecord.
 B. Thepumpisequippedwithavalveandhosewhichhasa
   checkvalvetopreventbackow.Thecheckvalveonly 
   workswhenthethehoseisdetachedfromthepump.
   Itisrecommendedtollthesystembeingtestedthrougha
   valvewhichcanbeshutforbackowpreventionaswell.

WARNING: Protect the pump from freezing. Store and
transport in a warm place. Or use food grade propylene
glycol in the pump to guard against freezing.
Safety and Precautionary Instructions:
