● Theinstallationworkshallbeperformedbythespecialistinstaller.
Ifitisnotcompleted,itmaycauseawaterleakage,anelectricshock,areorfallingdowntheunit.
● PerformtheelectricalworkaccordingtoInstallationManualandalltherelevantregulationandstandards.
Iftheinstructionsarenotfollowed,anelectricalshockandremayoccurduetoinsu󰀩cientcapacityand
inadequateperformance.
● Theelectricalwiringworkmustbeperformedbyauthorizedinstallers.
Ifnotperformingtheelectricalworkcompletelyoracapacityshortageofthepowercircuit,itmaycausean
electricshockorare.
Additionally,iftheearthwireisdisconnected,itmaycauseanelectricshock.
Contacttheauthorizedinstallerandconnecttheearthwiring.
● Ifthecircuitbreakerorfuseisoftenactivated,stopthesystemandcontactyourservicecontractor.
● Checkthatthegroundwireissecurelyconnected.Iftheunitisnotcorrectlygrounded,itleadelectric
shock.Donotconnectthegroundwiringtoagaspiping,waterpiping,lightingconductororgroundwiring
fortelephone.
● Usespeciedcablesbetweenunitsandchoosethecablescorrectly.Ifnot,anelectricalshockorremay
occur.
● Ensurethatthewiringterminalsaretightenedsecurelywiththespeciedtorques.Ifnot,generatingreor
anelectricalshockattheterminalconnectionpartmayoccur.
● Connectafuseofspeciedcapacity.
● Protectthewires,electricalparts,etc.fromratsorothersmallanimals.
Ifnotprotected,ratsmaygnawatunprotectedpartsandwhichmayleadtoare.
● Fixthecablessecurely.Externalforcesontheterminalscouldleadtoare.
● Provideasu󰀩cientlystrongfoundation.Ifnot,theunitmayfalldownanditmayleadtoinjuries.
● Iftheindoorunitisinstalledinasmallroomandtherefrigerantgasleakageoccurs,theleakedrefrigerant
gasllstheroomanditmaycausesu󰀨ocation.
Donotexceedthemaximumpermissibleconcentrationoftherefrigerantgasintheroom.
Consultwithdistributorforcountermeasuresuchaventilationsystem,etc.
● Beforeperforminganybrazingwork,checktoensurethatthereisnoammablematerialaround.
Whenusingtherefrigerantbesuretowearleatherglovestopreventcoldinjuries.
● Donotinstalltheunitinaplacewhereoil,vapor,organicsolventandcorrosivegas(ammonia,sulfur
compoundandacid)maybepresentinquantities.
Itmaycauserefrigerantleakageduetocorrosion,electricalshock,deterioratedperformanceand
breakage.
● Donotinsertangerorstickintotheairoutletandtheairinlet.
Itcouldcauseinjuryduetotouchtherotatingfanorelectricaldevices.
● Donotcontrolthewiredcontrollerbywethand.
Itmaycausefailureofthewiredcontrolleroranelectricshock.
● Donotuseanysprayssuchasaninsecticide,lacquer,hairsprayorotherammablegaseswithin
approximatelyone(1)meterfromthesystem.Itmaygenerateare.
● Donotinstalltheindoorunitinaplacewheretheairowblowsdirectlytoheatingappliances.
Itmaycauseincompletecombustionoftheheatingappliances.
● Whentheindoorunitisoperatedwithheatingappliances,ventilatearoomsu󰀩ciently.
Ifnot,itmaycausesu󰀨ocation.
● TurnOFFthemainpowersourceimmediatelyiftheprotectiondeviceisfrequentlyactivatedorthemain
powersourceswitchdoesnotwork.
Ifnot,itmaycauseanelectricshock,areorexplosionbecausetherearepossibilitiesoftheelectrical
leakageorovercurrent,etc.Contactyourdistributororcontractor.
