3. Before installation of the Drain Pump
3-1 Set up of the Drain Pump
● RemovethecoverandthemountingplatewhichisxedonthebackoftheDrainPumpeach.
* ThepackagingmaterialwhichisputbetweenthecoverandthemainbodyofDrainPumpisonlyforcushionfor
transportation.Takeitoutasitisunnecessary.
* Takeouttheaccessories.
● Runthepulltight(F)attachedthroughthesquareholeonthemountingplate.
● Cuttheknockoutholeonthecoverwithanipperandetc.
● Theinstallationplaceshouldbecarefullyconsideredifitisproper
forinstallation.Ifitisnotstrongenoughtoholetheunit,makeit
strongerbyusingboardorbeambeforeinstallation.
(1) Decidetheinstallationpositionofthemountingplatebyusingthe
paperpattern(G)attached.
(* Theleftendoftheindoorunitshouldbemarkedinadvance.)
1) Fixthepaperpatternonthewallwiththescrew(B)(M4×16)
attachedwithputtingittotheleftendoftheindoorunitfor
positioningoftheDrainPumpasshowninthedrawing.
2) Positionthemountingplatewithpushingitagainstthepaper
pattern.
(2) Fixthemountingplatewiththescrews(B)(M4×35)attached.Fix
themountingplateusingthe5dia.holes.
(6locationspointedbyarrowsinthedrawing.)
Incasethatthemountingplateisxedbyxingbolts(through
bolts,boltanchors,ornutanchors),getM10orW3/8screwslocally
andputthemintotwoø12holesofthemountingplatetoxit.
(3) Whenthemountingplatesisinstalled,removethepaperpattern.
(4) Checkthatthemountingplateislevelandpositionedcorrectly
withtheindoorunit.(Fig.2)
* Thescrewsremovedwillbeusedlater.Keepthemnottolose.

6-2 Installation of drain piping
● FixtheDrainPumponthemountingplate
(1) Installthescrewstothe2upperholes(indicatedbythearrowsshowninFig.7)
ofthemountingplatebyhandtighteningthemabouthalfway,andthenhook
theDrainPumponthescrews.
(2) LeveltheDrainPumpbyusingaspiritlevel.Thentightenthe4screwsse-
curelytoxtheDrainPump.
(1) Installtherefrigerantpipingusingtheleftpipingmethod.
(2) Whentherefrigerantpipinganddrainpipeareroutedverticallytogether,route
thepipingthroughthespaceinthemountingplate.
● Besurethattheindoorunitmustbepositionedattheplacewherewas
markedat4-1.
● ThebendingradiusoftherefrigerantpipemustbeR80orless.
● Thetuberaisedshouldbexedwiththepulltightwhichwasputthroughthe
squareholeofthemountingplate.
(3) Positiontherefrigerantpipingintheleftpipingspaceoftheindoorunitas
showninFig.8.
(1) Connectthedraintube(C)whichisinstalledtotheleftsidedrainportofthe
indoorunittothedrainportoftheDrainPump.
(2) Fixtheconnectionportsecurelywiththetubeclip(E)attached.
(3) Connecttheexibledraintube,whichisrunfromthetoppaneloftheDrain
Pump,tothelocaldrainpiping.Thepartconnectedmustbeclosedbyvinyl
chloridetypeglue.
(4) InsulatetheexibledraintubewhichisrunfromtoppanelofDrainPumpwith
thedraintubecover(D)attached.
(1) Thedrainpipeshouldbeinstalledinaccordancewiththefollowingprocedure.
● Thedrainpipeshouldbeinstalledsothattheoutdoorside(drainside)becomesfallingslope(1/100ormore)anddonotmake
traporpeaks.
● Thehorizontalrunofthedrainpipeshouldbe20morless.Incasethatthetubeiscrosscutsawingforlongdistance,some
supportbracketsshouldbeinstalledtopreventthepipefrombeingwavy.Neverinstalltheairbleeder.Thedrainwillblowout.
● ThehardvinylchloridepipeVP20(outerdia.26mm)shouldbeusedforthedrainpipe.Andthepartconnectedmustbe
closedbyvinylchloridetypegluetopreventwaterleak.
● Besuretowrapthedrainpipewithadiabaticmaterial(foampolyethylene:specicgravity0.03,thickness9mmormore)
availableonthemarket.
● Donotinstallstinktraptotheoutletofthedrainpipe.
● Theoutletofthedrainpipeshouldbeinstalledtheplacewhereitisnotpossibletocausestink.
● Incasethatpluraldrainpipesareinstalled,installthemainpipesothatitcomesapproximately10cmlowerthanthedrain
outletandthepipesmustbemadeofmaterialofVP30orsimilarandtheyshouldbefallingslope(1/100ormore).
● Itispossibletoraisetheoutletofthedrainpipeto80cm(max.lift)frombottomfaceofDrainPump.However,ifthereisa
horizontalrunpipeconnectedtotheverticalsectionofthedrainpipe,waterwilloverowfromthedrainpan.Thisisbecause
toomuchwaterwillowbackwhentheoperationstops.Therefore,thedrainpipemustberaisedvertically.Also,installthe
owbackstopatthehighestpointtopreventthewaterfromowbackfromhorizontalpartofthepipe.Seethedrawingbelow.

*WhentheDrainPumpisinstalledinwinterseason,thewatermustbedrained.
 Todrainwater,removethedrainplugundertheDrainPump.Preparethepantoreceivedrain.
 Whenthedrainagehasbeencompleted,putthedrainplugbackinplace.
(3)Afterchecking,putthecoverbackinplace.
*Makesurethattheleftendoftheindoorunitperfectlycomesonthepointmarkedat4-1.(Iftheydonotmatch,
