Thecleaning/circulatingsystemis
notoperatingcorrectly.
Verifythatskimmerbaskets,pumpbasketandotherscreensareclean.Cleanas
necessary.
Checkfilterandcleanasnecessary.
Checkvalvepositions.Adjustasnecessary.
NOTEMultiplepiecesofequipmentoperatingatonetime(forexample,waterfalls,spa
jets,andsurfacereturns)willaffecttheproperoperationofthecleaningsystem.
Checkthecleaningsystemmanualtoensurethatthesystemisadjustedaccordingtothe
manufacturer'srecommendations.
Bubblesarepresentinthepump
basket.
Airisinthesystem.Checkthepoolorspawaterleveltoensurethatitisattheproperlevel
andairisnotbeingdrawnintothesuctionpiping.Ifthewaterisatthenormallevel,turnoff
thepump.Turnthelid'slockingringcounter-clockwiseuntil'START'alignswiththeports.
RemovethelidandcheckfordebrisaroundthelidsealseatORimproperinstallationof
thelidseal,aseitherconditionwillallowairtoleakintothesystem.Cleanthelidsealand
replaceitonthelid.Replacethelidonthepumphousing.Align'START'withtheportsand
turnthelockingringclockwiseuntil'LOCKED'alignswiththeports.Hand-tightenthelidto
makeanair-tightseal.Do not use any tools to tighten the lid. Turnthepumpbackon.
Airleaksarestillpresent. Checkthesuctionsidepipingunion.Whilethepumpisrunning,trytotightentheunion.If
thisdoesnotstoptheairleak,turnoffthepump.Loosenbothunionsandslidethepump
outoftheway.Remove,clean,andre-installbothuniono-rings.
Repositionthepumpnexttothepipingandsecuretheunionnutstothepump.Withclean
uniono-rings,hand-tighteningoftheunionsshouldcreateaseal.Iftheunionsstilldonot
seal,gentlytightenwithalargepairoftongue-and-groovepliers.
Do not over-tighten.
Thereisnoairinthesystem,but
thepressureisstilllow.
Itispossiblethatdebrisiscaughtinthepumpimpeller.Thepumpimpellermovesthe
water,andthevanesintheimpellercanbecomeblockedwithdebris.SeeSection
6.2, Service Technician Maintenance, 6.2.1, Blocked Impeller, inthismanualformore
information.
Thereisnodebrisblockingthe
impellerandthepressureisstill
low.
Thepumpimpelleranddiffuserareshowingsignsofnormalwear.Haveaqualifiedservice
technicianchecktheimpelleranddiffuserandreplaceasnecessary.
Ifthepumpispartofarelativelynewinstallation,itcouldbeanelectricalproblem.Contact
aqualifiedservicetechnician.Havethetechniciancheckforlooseelectricalconnections
andcheckthevoltageatthepumpmotorwhileitisinoperation.Thevoltagemustbewithin
10%ofthemotor'sdataplaterating.Ifthevoltageisnotwithin10%,contactaqualified
electricianand/orthelocalpowerserviceprovider.
Pumpsealisleakingair.Haveaqualifiedservicetechnicianreplacetheseal.
Thepumpisleakingwaterbetween
themotorandpumpbody.
Thisiscausedbyadamagedorfailedmechanicalseal.Replacetheseal.SeeSection 6.2,
Service Technician Maintenance, 6.2.3, Mechanical Seal Replacement,inthismanual.
Thepumpgetshotandshutsoff
periodically.
Makesurethatthereisadequateroomaroundthemotortocirculateairandkeepthe
motorcool.Haveaqualifiedelectriciancheckforlooseconnectionsandcheckthevoltage
atthepumpmotorwhileitisinoperation.Thevoltagemustbewithin10%ofthemotor's
dataplaterating.Ifthevoltageisnotwithin10%,contactaqualifiedelectricianand/orthe
localpowerserviceprovider.
