CHECKING PRODUCT RECEIVED
●Uponreceivingthisproduct,inspectitforanyshippingdamage.
Inspectallelectricalconnections.Connectionsmustbecleanandtightattheterminals.
Claimsfordamageeitherapparentorconcealed,shouldbefiled immediatelywiththeshippingcompany.
NOTE:Roughhandlingmaydislocateinternalcomponents.
● Checkthemodelnumber,electricalcharacteristics(powersupply,voltageandfrequency)andaccessories
todetermineiftheyarecorrectwiththeorderingandshippinginformation,toensurethecorrectunithas
beenshipped.
Tominimizethepossibilityofdamageafterinspection,theunitsshouldbeinstalledandreassembledas
soonaspossible.
Thestandardinstallationandgeneraluseofthisunitisexplainedinthismanual.
Althoughcommonprocessesandproceduresforinstallingunitsarepresentedinthismanual,itsusefor
installationofunitsotherwiseindicatedinthismanualisnotrecommended.Pleasecontactyourlocalagent,

● Donotperforminstallationwork,refrigerantpipingwork,condensatepump,orcondensatepipingand
electricalwiringconnectionwithoutreferringtotheinstallationmanual.Iftheinstructionsarenotfollowed,
itmayresultinawaterleakage,electricshockorafire
●Usethespecifiednon-flammablerefrigerant(R410A)fortheoutdoorunitintherefrigerantcycle. Charge
onlyR410Aintotheunit.Donotchargeothermaterialsintotheunitsuchashydrocarbon refrigerants
(propane),oxygen,flammablegases(acetylene)orpoisonousgaseswheninstalling, maintainingand
movingtheunit.Theseflammablesareextremelydangerousandmaycausean explosion,afire,or
injury.Asoriginallymanufactured,thisunitcontainsrefrigerantinstalledbyHisense/HITACHI. Hisense/
HITACHIusesonlyrefrigerantsthathavebeenapprovedforuseintheunit’sintended countryormarket.
Hisense/HITACHI’sdistributorssimilarlyareonlyauthorizedtoproviderefrigerants that havebeen
approvedforuse inthecountriesormarketstheyserve.Therefrigerantusedinthisunit is identifiedon
theunit’sfaceplate and/orintheassociatedmanuals.Anyadditionsofrefrigerantintothis unitmust
complywiththecountry’s requirementswithregardtorefrigerantuseandshouldbeobtained from
Hisense/HITACHIdistributors.Useof unapprovedrefrigerantsubstituteswillvoidthewarranties andcan
causeinjuryordeath.
● Donotpourwaterintotheindoororoutdoorunit.Theseunitsareequippedwithelectricalparts.
Exposuretowatermaycauseaseriouselectricalshock.
● DonotopentheservicecoveroraccesspanelfortheindoororoutdoorunitswithoutturningOFFthemain
powersupply.
● Donottouchoradjustsafetydevicesinsidetheindoorunitoroutdoorunits.Ifthesedevicesaretouched
orreadjusted,itmaycauseaseriousaccident.
●Carefullycheckforescapingrefrigerantgas.Ifthereissignificantleakage,itcancausedifficultyin
breathing.TurnOFFthemainswitch,andcontactyourservicecontractorifrefrigerantleakageoccurs.
●Makesurethattherefrigerantleakagetestisperformed.
Refrigerant(fluorocarbonforthisunitisincombustible,non-toxicandodorless.
Howeveriftherefrigerantisleakedandcomesincontactwithfiretoxicgaswillgenerate.
Becausefluorocarbon isheavierthanair,thefloosurfacewillbefilled withit,whichcouldcause
suffocation.
● Theinstallerandsystemspecialistshallsecureagainstrefrigerantleakageaccordingtolocalregulations
orstandards.
●UseaEarthLeakageBreaker(ELB).
Intheeventoffault,thereisdangerofanelectricshockorafire ifitisnotused.

WARNING
●Donotuseanysprayssuchasinsecticide,lacquer,hairsprayorotherflammable gaseswithin
approximately1.3m(4ft)fromthesystem.
● Ifthecircuitbreakerorfuseisoftenactivated,stopthesystemandcontactyourservicecontractor.
● Checkthatthegroundwiringissecurelyconnected.Iftheunitisnotcorrectlygrounded,itmaycause
electricshock.Donotconnectthegroundwiringtogaspiping,condensatepiping,lightingconductoror
groundwiringfortelephones.
●Beforeperforminganybrazingwork,checktoensurethatthereisnoflammable materialaround.
Whenusingrefrigerant,besuretowearleatherglovestopreventinjuryfromcold.
● Insulateelectricalwiring,condensatepiping,andelectricalcomponentsfromthreatsposedbyburrowing
animalsandtemperatureextremes.Failuretodosocan,overtime,deterioratesystemperformance.
● Securethecables.Externalforcesontheterminalscouldleadtoafire.
●Tightentheflare nutwithatorquewrenchinthespecifi dmanner.Donotapplyexcessiveforcetothe
flare nutwhentightening.Ifyoudo,theflare nutcancrackandrefrigerantleakagemayoccur.
● Whenmaintaining,relocatingordisposingoftheunit,dismantletherefrigerantpipingafterthecompressor
stops.
● Highlydangerouselectricalvoltagesareusedinthissystem.Carefullyrefertothewiringdiagramand
theseinstructionswhenwiring.Improperconnectionsandinadequategroundingcancauseseriousinjury
ordeath.
● Performallelectricalworkinstrictaccordancewiththisinstallationandmaintenancemanualandall
relevantregulatorystandards.
● Usespecifiedcablesbetweenunits.
●Besuretoinstallcircuitbreakers(groundfaultinterrupter,isolatingswitch,moldedcasecircuitbreaker
andsoon),withthespecified capacity.Ensurethatthewiringterminalsaretightenedsecurelyto
recommendedtorquespecificationsIfacircuitbreakerorfuseisfrequentlyactivated,shutdownthe
systemandcontactyourservicecontractor.
● Clampelectricalwiressecurelywithacableclampafterallwiringisconnectedtotheterminalblock.
Inaddition,runwiressecurelythroughthewiringaccesschannel.
● Wheninstallingthepowerlines,donotapplytensiontothecables.Securethesuspendedcablesat
regularintervals,butnottootightly.
●Afterstoppingoperation,besuretowaitatleastfive minutesbeforeturningoffthemainpowerswitch.
Otherwise,waterleakageorelectricalbreakdownmayresult.Disconnectthepowersupplycompletely
beforeattemptinganymaintenanceforelectricalparts.Checktoensurethatnoresidualvoltageispresent
afterdisconnectingthepowersupply.
● Insulatetherefrigerantpipeconnectiontopreventcondensation.
●Besuretoattachthecoversothatitfits securelyontheelectricalboxwithoutanygaps.Securethe
cover withscrews.

NOTICE
● Becarefulthatmoisture,dust,orvariantrefrigerantcompoundsnotentertherefrigerantsystemduring
installationwork.Foreignmattercoulddamageinternalcomponentsorcauseblockages.
● Donotinstalltheindoorunit,outdoorunit,wiredcontrollerandcablewithinapproximately3m(10ft)of
strongelectromagneticwaveradiatorssuchasmedicalequipment.
● Afteralongshutdown,applypowertotheoutdoorunit(s)atleast12hourspriortooperationofthesystem
forpreheatingofthecompressoroil.
NOTE
● Itisrecommendedthattheroomisventilatedeverythreetofourhours.
●Theheatingcapacityoftheheatpumpunitisdecreasedaccordingtotheoutdoorairtemperature.
Therefore,itisrecommendedthatauxiliaryheatingequipmentbeusedinthefield whentheunitis
installedinalowtemperatureregion.
● Donotstepontheunit.
● Donotputanyforeignmaterialontheunitorinsidetheunit.
● Provideastrongandcorrectfoundationsothat:
● Theoutdoorunitisnotonanincline.
● Abnormalsounddoesnotoccur.
● Theoutdoorunitwillnotfalldownduetoastrongwindorearthquake.
