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.
