Besuretofollowtheinstructions. Besuretoestablishanearthconnection. Neverattempt.
•Aftercompletinginstallation,conductatrialoperationtocheckforfaultsandexplaintothecustomerhowtooperate
theairconditionerandtakecareofitwiththeaidoftheoperationmanual.
WARNING
•Askyourdealerorqualiedpersonneltocarryoutinstallationwork.
Donotattempttoinstalltheairconditioneryourself.Improperinstallationmayresultinwaterleakage,electricshocksorre.
•Installtheairconditionerinaccordancewiththeinstructionsinthisinstallationmanual.
Improperinstallationmayresultinwaterleakage,electricshocksorre.
•Besuretouseonlythespeciedaccessoriesandpartsforinstallationwork.
Failuretousethespeciedpartsmayresultintheunitfalling,waterleakage,electricshocksorre.
•Installtheairconditioneronafoundationstrongenoughtowithstandtheweightoftheunit.
Afoundationofinsufcientstrengthmayresultintheequipmentfallingandcausinginjury.
•Electricalworkmustbeperformedinaccordancewithrelevantlocalandnationalregulationsandwithinstructions
inthisinstallationmanual.Besuretouseadedicatedpowersupplycircuitonly.
Insufciencyofpowercircuitcapacityandimproperworkmanshipmayresultinelectricshocksorre.
•Useacableofsuitablelength.
Donotusetappedwiresoranextensionlead,asthismaycauseoverheating,electricshocksorre.
•Makesurethatallwiringissecured,thespeciedwiresareused,andthatthereisnostrainontheterminal
connectionsorwires.
Improperconnectionsorsecuringofwiresmayresultinabnormalheatbuild-uporre.
•Whenwiringthepowersupplyandconnectingthewiringbetweentheindoorandoutdoorunits,positionthewires
sothatthecontrolboxlidcanbesecurelyfastened.
Improperpositioningofthecontrolboxlidmayresultinelectricshocks,reoroverheatingterminals.
•Ifrefrigerantgasleaksduringinstallation,ventilatetheareaimmediately.
Toxicgasmaybeproducediftherefrigerantcomesintocontactwithre.
•Aftercompletinginstallation,checkforrefrigerantgasleakage.
Toxicgasmaybeproducediftherefrigerantgasleaksintotheroomandcomesintocontactwithasourceofre,suchasafanheater,
stoveorcooker.
•Wheninstallingorrelocatingtheairconditioner,besuretobleedtherefrigerantcircuittoensureitisfreeofair,
anduseonlythespeciedrefrigerant(R410A).
Thepresenceofairorotherforeignmatterintherefrigerantcircuitcausesabnormalpressurerise,whichmayresultinequipmentdamageand
eveninjury.
•Duringinstallation,attachtherefrigerantpipingsecurelybeforerunningthecompressor.
Iftherefrigerantpipesarenotattachedandthestopvalveisopenwhenthecompressorisrun,airwillbesuckedin,causingabnormal
pressureintherefrigerationcycle,whichmayresultinequipmentdamageandeveninjury.
•Duringpump-down,stopthecompressorbeforeremovingtherefrigerantpiping.
Ifthecompressorisstillrunningandthestopvalveisopenduringpump-down,airwillbesuckedinwhentherefrigerantpipingisremoved,

•Besuretoearththeairconditioner.
Donotearththeunittoautilitypipe,lightningconductorortelephoneearthlead.Imperfectearthingmayresultinelectricshocks.
•Besuretoinstallanearthleakagebreaker.
Failuretoinstallanearthleakagebreakermayresultinelectricshocksorre.
CAUTION
•Donotinstalltheairconditioneratanyplacewherethereisadangerofammablegasleakage.
Intheeventofagasleakage,build-upofgasneartheairconditionermaycausearetobreakout.
