2. ABOUT THE UNIT
2.1. Precautions for using R410A refrigerant
Thebasicinstallationworkproceduresarethesameasconventionalrefrigerant(R22)
models.
However,paycarefulattentiontothefollowingpoints:
Sincetheworkingpressureis1.6timeshigherthanthatofconventionalrefrigerant
(R22)models,someofthepipingandinstallationandservicetoolsarespecial.(See
thetablebelow.)
Especially,whenreplacingaconventionalrefrigerant(R22)modelwithanewrefrigerant
R410Amodel,alwaysreplacetheconventionalpipingandflarenutswiththeR410Apiping
andarenuts.
ModelsthatuserefrigerantR410Ahaveadifferentchargingportthreaddiametertopre-
venterroneouschargingwithconventionalrefrigerant(R22)andforsafety.Therefore,
checkbeforehand.[ThechargingportthreaddiameterforR410Ais1/2-20UNF.]
Bemorecarefulthatforeignmatter(oil,water,etc.)doesnotenterthepipingthanwith
refrigerant(R22)models.Also,whenstoringthepiping,securelysealtheopeningby
pinching,taping,etc.
Whenchargingtherefrigerant,takeintoaccounttheslightchangeinthecompositionof
thegasandliquidphases.Andalwayschargefromtheliquidphasewhererefrigerant
compositionisstable.
2.2. Special tools for R410A
Tool name Contents of change
Gauge manifold

AsanairconditionerusingR410AincurspressurehigherthanwhenusingR22,itisneces-
sarytochooseadequatematerials.
WARNING
Donotusetheexisting(forR22)pipingandarenuts.
Iftheexistingmaterialsareused,thepressureinsidetherefrigerantcyclewillriseand
causefailure,injury,etc.(UsethespecialR410Amaterials.)
Wheninstallingandrelocatingtheairconditioner,donotmixgasesotherthanthe
