Especially,whenreplacingarefrigerantR22modelwithanewrefrigerantR32model,
alwaysreplacetheconventionalpipingandflarenutswiththeR32andR410Apipingand
arenutsontheoutdoorunitside.
ForR32andR410A,thesamearenutontheoutdoorunitsideandpipecanbeused.
ModelsthatuserefrigerantR32andR410Ahaveadifferentchargingportthreaddiam-
etertopreventerroneouschargingwithrefrigerantR22andforsafety.Therefore,check
beforehand.[ThechargingportthreaddiameterforR32andR410Ais1/2-20UNF.]
BemorecarefulthanR22sothatforeignmatter(oil,water,etc.)doesnotenterthe
piping.Also,whenstoringthepiping,securelysealtheopeningbypinching,taping,etc.
