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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R410AincurspressurehigherthanwhenusingR22,itis
necessary 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.

CAUTION
• To prevent breaking of the pipe, avoid sharp bends.
• If the pipe is bent repeatedly at the same place, it will break.
6.6.3. Pipe connection
CAUTION
• Be sure to Install the pipe against the port on the indoor unit correctly. If the center-
ingisimproper, the arenutcannottightensmoothly.Ifthe are nut is forced to
turn, the threads will be damaged.
•Donotremovethearenutfromtheindoorunitpipeuntilimmediatelybeforecon-
necting the connection pipe.
• Hold the torque wrench at its grip, keeping it in the right angle with the pipe, in order
totightenthearenutcorrectly.
•Tighten the are nuts with a torquewrenchusingthespeciedtighteningmethod.
