Installthedrainpipeoftheindoorunit
Youcanuseapolyethylenetubeasthedrainpipe
(out-dia.37-39mm,in-dia.32mm).Itcouldbe boughtatlocal
marketorfromyourdealer.
Setthe mouthofthe drainpipe ontothe rootofthebody's
pump-pipe,and clipthedrainpipe and the out-letpipe sheath
(fittings)together firmly withthe out-letpipeclasp(fitting).
Thebody'spumppipeandthedrainpipe(especiallythe
indoor part)shouldbe covered evenlywiththeout-letpipe
sheath(fittings)and be boundtightlywiththe constrictor to
preventcondensation caused by enteredair.
Topreventwaterfromflowingbackwardsintothe air
conditioner whilethe airconditioner stops,pleaselean the
drainpipe down toward outdoor (outlet-side) atadegree of
over1/50.And pleaseavoidanybulge or water deposit. (
Refer toFig.5-17.ainthe figurepage)
Donotdrag thedrainpipeviolentlywhenconnectingto

Inthe caseofprolonged drainpipe,youhad better tighten its
indoor partwithaprotection tube topreventitfromloosing.
Ifthe outletofthe drainpipe ishigherthan the body'spump
joint,the pipeshouldbe arranged asverticallyaspossible.
Andthe liftdistancemustbe less than 200mm,otherwisethe
water will overflowwhen the airconditioner stops. (Referto
Fig.5-18inthe figure page)
The end ofthedrainpipe shouldbe over50mmhigher than
the ground or the bottomofthedrainage chute,anddonot
immerseitinwater.Ifyou discharge the waterdirectlyinto
sewage,be suretomakeaU-formaquasealbybending the
pipe up topreventthe smellygasentering the housethrough
