WL500WaterTreatment
Systemtooperateproperly.
Thecorrectinputwaterpressureiscriticaltotheperformanceof
theunittoallowsolenoidstoopen.

Checkwaterpressureattheinletbulkheadwithawaterpressure
gauge.

Additionalmethodofverificationistoturnoffwatertounitand
pressthedispensebutton.Doesthesolenoidopenwithoutwater
pressuretotheunit?Listenforsolenoidtoactivate(notjustthe
dispensebutton“click”)


2. RunOn

“RunOn”or“CarryOn”ispresentinallWaterlogicpressurefedunitswithoutoutletsolenoids.

“RunOn”isdefinedastheamountofwaterthatcontinuestodispenseoutofthefaucetafter
releasingthedispensebutton.RunOnexistsbecausethetankspressurizeaswaterisbeing
dispensed.EveryWaterlogictankhasanoutletrestrictortoensurethetanksremainfullofwater
andwateriscontrolledasitisreleasedtothefaucet.Theinletsolenoidcontrolsflowintothetanks.
Thetankswill“depressurize”oncethedispensebuttonisreleasedtheinletsolenoidcloses.Asmall
amountofwaterwill“RunOn”throughthefaucetasthetankdepressurizestoatmospheric
conditions.Typical“RunOn”is2‐3seconds.“RunOn”canbereducedbyinstallingapressure
limitingdevice.

Theamountofinletorsupplypressuredirectlyimpactstheamountof“RunOn”asquantified

3. LowFlowofWater–RatedServiceFlowis1.89Liters(0.5gallons)perMinute

PossibleReason Solution
DetermineFlowof
Water
RatedFlowRateis1.89Liters(0.5gallons)perminute.Checkflow
ratebydispensingintoacontainertomeasureforoneminuteand
measuretheamountofwaterthatwasdispensed.
FeedLinestoosmall
Feedlinescanrestrictflowifrunlongdistancesfromthesupply.It
maybenecessarytoincreasethesupplyline(e.g.,use3/8”feedline
vs.¼”.
Elbowsandturnsin
thefeedline Minimizeelbowsandturnsinthefeedline.
Filters
Filterswithhighpressuredropduetofoulingorjustbydesign.
Changefiltersmorefrequentlyorgotohighermicronsizefilterfor
localwaterconditions.
Restrictions
Followflowpathtoensuretherearenoundiscoveredrestrictionsdue
todebrisormalfunctioningvalves,includingthesupplyvalveatthe
source.
BoosterPump Addaboosterpumptothesupplylineifthefeedisslowerthan
needed.
