SAFETY SUMMARY
● Donotperformtheinstallationwork,refrigerantpipingwork,drainpump,drainpipingandelectricalwiring
connectionwithoutreferringtoourinstallationmanual.Iftheinstructionsarenotfollowed,itmayresultin
awaterleakage,electricshockorre.
● Usethespeciedrefrigerant(R410AorR32)totheoutdoorunitintherefrigerantcycle.
DonotchargetheunitwithmaterialotherthanR410AorR32,suchashydrocarbonrefrigerants(propane
oretc.),oxygen,ammablegases(acetyleneoretc.)orpoisonousgaseswheninstalling,maintainingand
movingtheunit.Theseammablesareextremelydangerousandmaycauseanexplosion,re,andinjury.
● Donotpourwaterintotheindoororoutdoorunit.Theseproductsareequippedwithelectricalparts.
Ifwaterispoured,itwillcauseaseriouselectricalshock.
● DonotopentheservicecoveroraccesspanelfortheindoororoutdoorunitwithoutturningOFFthemain
powersupply.
● Donottouchoradjustsafetydevicesinsidetheindoorunitoroutdoorunit.Ifthesedevicesaretouched
orreadjusted,itmaycauseaseriousaccident.
● Refrigerantleakagecancausedi󰀩cultywithbreathingduetoinsu󰀩cientair.TurnOFFthemainswitch,
extinguishanynakedamesandcontactyourservicecontractor,ifrefrigerantleakageoccurs.
● Makesurethatarefrigerantleaktesthasbeenperformed.Refrigerant(FluorocarbonorDiuoromethane)
forthisunitisnon-toxic,andodorless.Iftherefrigerantshouldsomehowescapeandcomeintocontact
withame,toxicgaswillform.Thisgasisheavierthanairandwillsettlenearoorareasandspread
whereitcancausesu󰀨ocationtothosenearby.Inaddition,diuoromethaneisammableandcancause
re.
● Theinstallerandsystemspecialistshallsecuresafetyagainstrefrigerantleakageaccordingtothelocal
regulationsorstandards.
● UseanELB(EarthLeakageBreaker).
Intheeventoffault,thereisdangerofanelectricshockorreifitisnotused.
● Donotinstalltheoutdoorunitwherethereishighlevelofoilmist,ammablegases,saltyairorharmful
gasessuchassulfur.
● Forinstallation,rmlyconnecttherefrigerantpipebeforethecompressorstartsoperating.
Formaintenance,relocationanddisposal,removetherefrigerantpipeafterthecompressorstops.
● Donotperformashortcircuitoftheprotectiondevices,suchasthepressureswitchduringoperation.
Itmaycauseareandexplosion.
