2. ABOUT THE PRODUCT
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withthe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
Pressureishighandcannotbemeasuredwith a conven-
tional(R22)gauge.Topreventerroneousmixing of other
refrigerants,thediameterofeachporthasbeenchanged.
Itisrecommended thegaugewith seals -0.1to5.3 MPa
(-1to53bar)forhighpressure.
-0.1to3.8MPa(-1to38bar)forlowpressure.
Charge hose
Toincreasepressureresistance,thehosematerialandbase
sizewerechanged.
Vacuum pump
A conventionalvacuumpumpcanbeusedbyinstallinga
vacuumpumpadapter.
Gas leakage detector SpecialgasleakagedetectorforHFCrefrigerantR410A.
Copper pipes
Itisnecessarytouseseamlesscopperpipesanditisdesirablethattheamountofresidual
oilisless than 40mg/10m.Do notusecopperpipeshaving a collapsed,deformedor
discoloredportion(especially on the interior surface). Otherwise, the expansion valueor
capillarytubemaybecomeblockedwithcontaminants.
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 specied refrigerant (R410A) to enter the refrigerant cycle.
Ifairorothergasenterstherefrigerantcycle,thepressureinsidethecyclewillriseto
anabnormallyhighvalueandcausefailure,injury,etc.
