1.Introductionandscopeofapplication
CongratulationsonpurchasingyourRAINMASTEREco(RMEco).
TheRMEcoisspeciallydesignedforrainwaterandgreywaterharvestinginsinglefamilydwellings.
Optimisedforthewaterrequirementsofsmallfamilies,andusingdiaphragmpumptechnology,the
RMEcoisthefirstrainwatermoduletoofferupto70%lowerpowerconsumptionwhencomparedto
conventionalrainwatermodules.
TheRMEcoiscompatiblewiththefollowingcombinations:

Toilet/Urinal:
Youcanconnectuptothreetoiletsandoneurinal.

Note:
Themaximuminstallationheightfortoiletsandwashingmachines,
abovetheRMEcocontrolunit,is6m.Thefillingtimeoftoiletcisterns
increaseswiththesimultaneousflushingof2ormoretoilets.Ifaurinal
isusedinparalleltoothertoilets,thentheflowpressuremaynot
alwaysbesufficient.


Washingmachine:
Youcanconnectuptotwowashingmachines.

Note:
Ifmorethanonewashingmachineisconnected,oratthesametime
forexample,thegardenisbeingwatered,thendependingonthetype
ofwashingmachineused,yoursupplymaybeinterruptedifthewater
doesnotfillfastenough.Inthatcase,youmayhavetostartthe
washingmachinetime‐shifted.


Garden/Cleaning:
Forsmallwateringandcleaningtasks,agardentapcanbeconnected.
Fromthis,thefollowinggardenconsumersmaybesupplied:
‐ a20mgardenhosewithspraynozzle,or
‐ asmalllawnsprinkler‐upto2bar(29psi)/500l/hRMEco10
‐ asmalllawnsprinkler‐upto2bar(29psi)/800l/hRMEco14
‐ ahighpressurecleaner‐upto500l/hRMEco10orupto800l/h

1.1Modesofoperation

Automaticmode
InAutomaticmode,thediaphragmpumpcarriesrainwaterfromthetankintothehomeandonto
respectiveapplications(e.g.toiletsetc.).Ifthetankisempty,thisisthendetectedbythefloatswitchin
thetankwhichinstructstheelectronic3/2‐waymotorisedballvalvetochangetothemainswatermode.
Thesuctionlineisthenblockedandtherequiredmainswateristakenfromthebuilt‐insupplemental
supplycontainerwithintheRMEco.Whentherainwatertankisrefilledbackwithrainwater,thefloat
switchdetectsthisandtheelectronic3/2‐waymotorisedballvalveswitchesbacktotherainwaterintake
setting.
Maintenancemode
InMaintenancemode,the3/2‐wayballvalveswitchespermanentlytomainswatermode,wherethe
consumeriscontinuouslysuppliedfromthesupplementalsupplycontainer.
Inbothmodes,thepoweronandoffofthediaphragmpumpisdonebymeansofthebuilt‐inpressure
switch.Theanti‐dryrunningprotectionofthediaphragmpump,andthestagnationprotectionofthe
supplementalwatersupply(theregularrefreshingofwaterinthesupplementalsupply)areautomatically
controlledbytheunit‘sbuilt‐inelectronics.
Optionallyfilllevelstatusindicator(RMEco‐FS)oranexternalchargingpump(RMEco‐LP)forboosting
waterintakecanbeconnectedtotheboard.

building.Thebrickworkbehindthewater‐carryingsystemmustbeprotectedfromwater(suchas
withwater‐resistantpaint).
Makesurethattheexistingemergencyoverflowsareconnectedandadequatelysized.
Removethemainsplugifyouwillbeawayformorethan24hours.Lockthefreshwaterlineat
theinletofthedeviceifyouwillbeawayformorethan24hours
Allproductsmustberegularlyinspectedtomaintainpropercondition.Theminimuminspection
intervalismentionedinthemaintenancemanual.

4.2.Dimensioningoftheintakeline

Inpractice,thepumpautomaticallystartsintakeduetodecreaseinpressure(pipefriction,intakelevel)
onlyinacertainrange.Inthisoperatingrange,itevacuatestheairfromthepumpindependentofthe
suctionline(forexample,withinitialstartupoperation).Theintakecharacteristiclineindicatesthe
dependenceofintakelengthontheintakelevel.Thedeterminedvalueisabovetherepresentedintake
lineinthediagram.Iftheintakepointisbelowtheintakeperformanceline,thenachargingpump
(optionalaccessoryRMEco‐LP)isusedtoensuretheintakeprocessproceedsreliablyandwithsufficient
safety.
Note:Thechargingpumpbooststhewaterintakepressure,sothatanintakelevelofupto3mhighcanbe
attained.Thismeansthat,theperformancecurvemoves3m(9.8ft)paralleltowardsdown.

5.5Componentsofthepressurelineset

Thepressurelinesetcontainsanexpansiontank,whichisnecessarytoensurethesilentoperationofthe
system.Aprimarypressureof2.0barispreloadedatmanufacture.Theexpansiontankensuresthatthe
vibrationcreatedbytheoperationofthepumpisnottransmittedthroughthepipingsystem.

Procedureforpressurecontrol/maintenanceoftheprimarypressure:

1.) DisconnectthemainspowertotheRMEco.

2.) Closethepressureshut‐offvalve.


3.) Opentheventcockfordrainingthesystempressureto0bar.




4.) Checktheairpressureintheexpansiontankwithanairpump
(withpressuregauge).Youcanuseabicyclepumporcartyre
pump.
Shouldtheprimarypressurebetoolow,useyourpumpto
increaseittothedesiredpressure.


5.) Reconnectthemainspowertostarttheunitagainanddrainthe
water,viatheventcock,untilbubblefreewatergushesout.



6.) Closetheventcockandopenthepressureshut‐offvalve.

Thesystemisnowreadytouse.

6.1Wallmounting

TheRMEcoismountedonthewallusingthemountingmaterialprovided.Thelid,bottomandlateral
distancesindicatedshouldbeadheredtowhenmountingtoprovideclearmaintenanceaccess.

Inordertoavoidvibrations,theRMEcomustbefixedwithall

6.2Connectiontothemainswaterline

Theconnectiontothemainswaterlineisdonewiththeprovidedflexiblehosewithstopcock.

Note:
Theflexiblehosemustnotbemountedwithtension,sincetheinternalfloatvalveispressedagainstthe
innerwallfromhere.
Allprovidedflexiblehoseshaveglandscrewswithflatseals.Therubbersealsmustbepresent.Additional
sealingmaterialmustnotbeusedatglandnuts!


Screwtheglandscrewintothecontainerconnectionand
carefullytightenwitha30inchfixedspanner.

6.3Installationontheintakeside

Theinstallationoftheintakerequiresspecialattention,sinceonlycorrectmountingandsealingensures
trouble‐freeoperationofthesystem.Forfault‐freefunctioning,ensuretheguidelinesconcerningintake
heightandintakelengtharefollowedcarefully(seeChapter4.2.).






6.3.1Installationofaprotectiveconduitpipe

Theintakelinemustbeinstalledina(e.g.DN100)protectiveconduitpipeinordertoensureallintakelines
andpipescanbeaccessedfreelyatanytime.Inordertoavoidwateraccumulatingintheconduit,itmust
beinstalledwith>1%slopebacktowardsthetank.

Ingeneral,alllinescarriedintheprotectivepipeshouldpassthroughawallbush(forexample
INTEWAMD100Articlenumber:610050),atthehouse.Throughthisbush,theintakepipeandthefloat
switchcableareroutedandsealedbyapressedrubberplate.Thispreventswaterfromoutsideentering
thebasement/garage/utilityroom.Thewallbushmustbemountedasperinstructionssothattheintake
lineisneversqueezed(contractionofcrosssection!).
