StartUpProcedure

1. SettheredhandlesonthebypassvalvetotheServiceposition.
2. BeforeplugginginBubble‐Up®JrInteractive™,identifytheplug‐incords.Seefigure8.
3. Pluginthemetercontrolandwateralarmvalvecontrolpowercords.
4. Pushresetbuttononwateralarmvalvecontrolfor3secondstoopenthemotorizedballvalve.
5. Plugintheyellowcordfirst.Theblowershouldstart,andthesolenoidvalveshouldopentobeginfillingthe
tank.
6. Asthewaterlevelinthetankrises,thefillfloatswitchwilltiltup.Thiswillstoptheblowerandclosethe
solenoidvalve.
7. Oncethetankisfull,plugintheblackpumpcontrolcord.
8. Ifthepumpdoesnotstartdeliveringwatertothehouse,itmaybenecessarytoprimethepump.(Normallyyou
willonlyhavetodothisonce,whentheunitisfirstinstalled.)Thepumpissuspendedbyapipeunderneaththe
pumpcontrol.Unscrewtheunionandmovethepumpcontrolofftotheside.Youmayneedtosiphonor
vacuumthewaterupthispipetoremovetheairfromthepumpandprimeit.
9. Oncetheairhasbeenremovedfromthepump,replacethepumpcontrolandtightentheunion.Pluginthe
pump.Ifthepumpdoesnotstartdeliveringwatertothehouse,repeattheprimingsequence.
10. Aftertheunitisoperating,runaradontestoftherawwaterandthefilteredwatertoensurethattheunitis
reducingradonlevelsinthewater.

RadonTestingNote:Itisimportanttoinstallanewsamplevalveorboilerdraininnewpipingsothattheradontesting
isnotinfluencedbyoldpiping.

11. Performthesix‐monthmaintenanceprocedure,andfillouttheStart‐UpDatapageattheendofthismanual.



MainUnit
Theunitshouldnotneedanyoperatorattention.Whenwaterisusedinthehouse,the2.1gallonwaterexpansiontank
deliverswaterdemand.Whenthepressuredropstothesetpressure,themechanicalpumpcontrolstartstheBubble‐
Up®JrInteractive™pumptodeliverwatertothehomeandrefillthe2.1gallonwaterexpansiontank.Whenthe
mechanicalpumpcontrolsensesnormalhouseholdpressure,themechanicalpumpcontrolshutstheBubble‐Up®Jr
Interactive™pumpoff.AsthewaterlevelfallsintheBubble‐Up®JrInteractive™maintank,thefloatswitchpowersthe
blowerandsolenoidtofilltheBubble‐Up®JrInteractive™tankwithtreatedwater.

LowWaterCut‐OutFloatSwitch
ThepumpwillautomaticallystopwhenthereislowwaterintheBubble‐Uptank.Thepumpwillautomaticallyrestart
whenwaterisreplenished.

WaterAlarmValve
Thewateralarmvalveisinplaceforprotectionagainstleakingoroverflowingandwillnotoperateunlessoneofthese
thingshappens.Oncethewateralarmvalvecontrol,overflowalarmfloat,floorsensororterminalblocksensesa
probleminthesystemthewateralarmvalvecontrolactivatesthemotorizedballvalveandshutsofftheincoming
water.Thewateralarmvalvecontrolwillalsosoundanalarmtoidentifythatthereisaproblem.


TroubleshootingforBubble‐UpMechanicalPumpController

Low‐WaterPumpCut‐out
Alowwaterfloatswitchisusedtoturnoffthepumptoprotectitfromrunningdry.Thepumpwillautomaticallyrestart
whenwaterlevelreturnstonormal.Ifthewateralarmvalveorsolenoidisstuckclosed,incomingwaterwillnotbe
allowedtoentertheBubble‐Up®JrInteractive™maintank.Thiswillcausethetanktoemptyandthelowwaterfloatto
turnoffthepumptoprotectitfromrunningdry.Ifthewellpumpfailstherewillbenowaterenteringthemaintankof
theBubble‐Up®JrInteractive™alsocausingthelowwaterfloattoturnoffthepumptoprotectitfromrunningdry.

NoWaterfromtheBubbleUp(noalarmissounding)
Cause:LowwaterfloatswitchshutoffBubble‐Up®Jrpump.

Example:TheBubbleUpInteractiveincludesalowwaterfloatswitchtostoptheBubble‐Up®Jrpumpfromdelivering
waterflowtothehousewhenthewaterlevelintheBubbleUptankistoolow.Thisprotectsthepumpfromrunningdry.
ThisfloatswitchwillautomaticallyrestarttheBubbleUppumponcewaterlevelrisestonormallevels.


Bubble‐Up®JrInteractive™RadonRemovalSystem
15
ThissituationcanbecausedbysimplyusingmorewateroutoftheBubble‐Up®Jrthanwhatiscomingin.Comparewater
outletflowwith“currentflow”metercontrolreadingontheBubble‐Up®Jrwhilefilling.

Afewinletflowproblemsare;lowyieldwell,wellpumpfailure,cloggedplumbingorwaterfiltrationrestrictingwaterflow
fillingtheBubble‐Up®Jr.
NowaterfromtheBubbleUp(alarmissounding)
Cause:WaterAlarmValveshutwaterofftoBubble‐Up®Jr.

Example:TheBubble‐Up®JrInteractiveincludesawateralarmvalvewhichsoundsanalarmandstopswaterfillingthe
BubbleUpwhenaleakoroverflowconditionisdetected.OncewaterstopsfillingtheBubble‐Up®Jr,continuedwateruse
willcausethelowwaterfloatswitchtostoptheBubbleUppumpfromdeliveringwaterflowtothehouse.

Examples:ThealarmconditionstocausethewateralarmvalvetocloseandstopwaterfromenteringtheBubble‐Up®Jr
are;1‐ thewatersensorboxdetectswaterontheflooraroundtheBubble‐Up®Jr2‐ thewatersensorterminalblock
detectswaterontopoftheBubble‐Up®Jror3‐thehighwaterfloatswitchsenseshighwaterinthemaintank.

Theseconditionsarecausedbywaterdetectionduetohighwaterlevels,waterleaks,condensationEtc.

AlsoiftheairventpipingisrestrictedtheBubble‐Up®JrblowercannotfreelyblowtheairoutoftheBubble‐Up®Jr.This
willcauseblowerbackpressurewhichwillforcewateruptheoverflowpipetobereleasedthroughthebreathervent,
causingthesensorsontheterminalblocktodetectanoverflowofwater.Ventpipingbackpressurecanbecausedbyan
obstruction,icebuild‐up,watertrappedinareversepitch,excesspipefittingsorpipelength.

High‐WaterAlarm
Afewthingscancausethehigh‐wateralarmvalvecontroltosound:
Theleakdetectionterminalblockorfloorsensoriswet,repairleakanddryoffthetopoftheBubble‐Up®Jr
Interactive™.
Ventlineisobstructed,forcingthewateruptheoverflowandtriggeringtheterminalblocksensors.Clear
obstruction.
HighwateralarmfloatistriggeredduetooverfillingthemaintankoftheBubble‐Up®JrInteractive™.Thiscanbe
causedbyafailedorstucksolenoid,tangledfloatswitchassembly,orafailedfloatswitchassembly.Checktosee
thatsolenoidandfloatswitchareworkingproperlyandreplaceifnecessary.

