6)Whencarryingoutpipingconnection,takecarenottoletairsubstancesotherthanthespeciedrefrigerantgointorefrigerationcycle.Otherwise,it
willcauselowercapacity,abnormalhighpressureintherefrigerationcycle,explosionandinjury.
7)Donotdamageoruseunspeciedpowersupplycord.Otherwise,itwillcausereorelectricalshock.
8)Thisequipmentmustbeearthed.Itmaycauseelectricalshockifthegroundingisnotperfect.
9)Donotinstalltheunitatplacewhereleakageofammablegasmayoccur.Incasegasleaksandaccumulatesatsurroundingoftheunit,itmaycause
re.
CAUTION
1)Selectionoftheinstallationlocation.
Selectainstallationlocationwhichisrigidandstrongenoughtosupportorholdtheunit,andselectalocationforeasymaintenance.
2)Donotreleaserefrigerant.
Donotreleaserefrigerantduringpipingworkforinstallation,reinstallationandduringrepairingarefrigerationparts.Takecareoftheliquidrefrigerant.
itmaycausefrostbite.

thathooksoffourcornersarexedwell.
NOTE: Aftercompletion ofinstallingthebody,
thefourbolts (M6X12)mustbefastenedtothe
airconditionerto ensure the bodyisgrounded
well.

  e. Keepfastening thescrewsunderthepanel hooks,until thethicknessofthe spongebetween thebodyandthepanel’soutlethasbeen
reducedtoabout4~6mm.Theedgeofthepanelshouldcontactwiththeceilingwell.(Refertochart12)
   ●MalfunctiondescribedinChart13canbecausedbyinappropriatetightnessthescrew.
   ●Ifthegapbetweenthepanelandceilingstillexistsafterfasteningthescrews,theheightoftheindoorunitshouldbemodiedagain.(Refer
tochart14-left)
   ●Youcanmodifytheheightoftheindoorunitthroughtheopeningsonthepanel’sfourcorners,iftheliftoftheindoorunitandthedrainpipe
isnotinuenced.(Refertochart14-right)
(4)Hangtheair-ingridtothepanel,thenconnecttheleadterminatoroftheswingmotorandthatofthecontrolboxwithcorresponding

A. Install the drainpipe of the indoor unit .
 ●Youcanuseapolyethylenetubeasthedrainpipe(out-dia,37-39mm,in-dia.32mm).Itcouldbeboughtatlocalmarketorfromyourdealer.
 ●Setthemouth ofthedrainpipeontotherootofthebody’spump-pipe,andclipthedrainpipeandtheout-let pipesheath(ttings)together
rmlywiththeout-letpipeclasp(ttings).
 ●Thebody’spumppipeandthedrainpipe(especiallytheindoorpart)shouldbecoveredevenlywiththeout-letpipesheath(ttings)andbe
boundtightlywiththeconstrictortopreventcondensationcausedbyenteredair.
  ●Topreventwaterfromowingbackwardsintotheairconditionerwhiletheairconditionerstops,pleaseleanthedrainpipedowntoward
outdoor(outlet-side)atadegreeofover1/50.Andpleaseavoidandbulgeorwaterdeposit.(Refertochart16.a)
  ●Donotdragthedrainpipeviolentlywhenconnectingtopreventthebodyfrombeingpulled.Meanwhile,onesupport-pointshouldbesetevery
1~1.5mtopreventthedrainpipefromyielding(Refertochart16.b).Oryoucantiethedrainpipewiththeconnectingpipetoxit.(Referto
chart16.c)
  ●Inthecaseofprolongeddrainpipe,youhadbettertightenitsindoorpartwithaprotectiontubetopreventitfromloosing.
  ●Iftheoutletofthedrainpipeishigherthanthebody’spumpjoint,thepipeshouldbearrangedasverticallyaspossible.Andtheliftdistance
mustbelessthan200mm,otherwisethewaterwilloverowwhentheairconditionerstops.(RefertoChart17)
  ●Theendofthedrainpipeshouldbeover50mmhigherthanthegroundorthebottomofthedrainagechute,anddonotimmerseitinwater.If
youdischargethewaterdirectlyintosewage,besuretomakeaU-formaquasealbybendingthepipeuptopreventthesmellygasentering
