WARNING
•Donotusetappedwires,strandedwires,extensioncords,orstarburstconnections,astheymaycauseoverheating,
electricalshock,orre.
•Donotuselocallypurchasedelectricalpartsinsidetheproduct.(Donotbranchthepowerforthedrainpump,etc.,fromthe
terminalblock.)Doingsomaycauseelectricshockorre.
•Besuretoinstallanearthleakdetector.(Onethatcanhandlehigherharmonics.)
(Thisunitusesaninverter,whichmeansthatitmustbeusedanearthleakdetectorcapablehandlingharmonicsinorderto
preventmalfunctioningoftheearthleakdetectoritself.)
•Useanall-poledisconnectiontypebreakerwithatleast3mmbetweenthecontactpointgaps.
•Donotconnectthepowerwiretotheindoorunit.Doingsomaycauseelectricshockorre.
•Donotturnonthesafetybreakeruntilallworkiscompleted.
1)Striptheinsulationfromthewire(20mm).
2)Connecttheconnectionwiresbetweenthe
indoorandoutdoorunitssothattheterminal
numbersmatch.Tightentheterminalscrews
securely.Werecommendaatheadscrewdriver
beusedtotightenthescrews.Thescrewsare
packedwiththeterminalboard.
