Pleaserequestyoursalesagentorqualiedtechniciantoinstallyourunit.Waterleakage,
shortcircuitorremayoccurifyoudotheinstallationworkyourself.
●
Pleaseobservetheinstallationstatedintheinstallationmanualduringtheprocessof
installation.Improperinstallationmaycausewaterleakage,electricshockandre.
●
Makesurethattheunitsaremountedatlocationswhichareabletoprovidefullsupportto
theweightoftheunits.Ifnot,theunitsmaycollapseandimposedanger.
●
Observetherulesandregulationsoftheelectricalinstallationandthemethodsdescribed
intheinstallationmanualwhendealingwiththeelectricalwork.Usecableswhichare
approvedo󰀩cialinyourcountry.Besuretousethespeciedcircuit.Ashortcircuitand
remayoccurduetotheuseoflowqualitywireorimproperwork.
●
Besuretousethespeciedcablesforconnectingtheindoorandoutdoorunits.Please
ensure that the connections are tight after the conductors of the wire are inserted into the
terminalstopreventtheexternalforceisbeingappliedtotheconnectionsectionofthe
terminalbase.Improperinsertionandloosecontactmaycauseover-heatingandre.
●
Pleaseusethespeciedcomponentsforinstallationwork.Otherwise,theunitmay
collapseorwaterleakage,electricshock,reorstrongervibrationmayoccur.
●
BesuretousethespeciedpipingsetforR410A,R32.Otherwise,thismayresultin
brokencopperpipesorfaults.
●
Wheninstallingortransferringanairconditionertoanotherlocation,makesurethat
airotherthanthespeciedrefrigerant(R410A,R32)doesnotentertherefrigeration
cycle.Ifotherairshouldenter,thepressureleveloftherefrigerationcyclemayincrease
abnormallywhichcouldresultinaruptureandinjury.
●
Be sure to ventilate fully if a refrigerant gas leak while at work. If the refrigerant gas
comesintocontactwithre,apoisonousgasmayoccur.
●
Aftercompletionofinstallationwork,checktomakesurethatthereisnorefrigerationgas
leakage.Iftherefrigerantgasleaksintotheroom,comingintocontactwithreinthefan-
drivenheater,spaceheater,etc.,apoisonousgasmayoccur.
●
Unauthorizedmodicationstotheairconditionermaybedangerous.Ifabreakdown
occurspleasecallaqualiedairconditionertechnicianorelectrician.Improperrepairs
mayresultinwaterleakage,electricshockandre,etc.
●
Besuretoconnecttheearthlinefromthepowersupplywiretotheoutdoorunitand
betweentheoutdoorandindoorunit.Donotconnecttheearthlinetothegas
tube,waterpipe,lightingrodortheearthlineofthetelephoneunit.
Improperearthingmaycauseelectricshocks.
●
Whennishingtherefrigerantcollection(pumpingdown),stopthecompressorandthen
removethecoolantpipe.
Ifyouremovetherefrigerantpipewhilethecompressorisoperatingandtheservicevalve
isreleased,airissuckedandapressureinthefreezingcyclesystemwillbuildupsteeply,
