6. Drain piping
1)Connectthedrainhose,asdescribedright.
The drain hose should
be inclined downward.
No trap is permitted.
Do not put the end
of the hose in water.
2)Removetheairltersandpoursomewaterintothedrainpantocheckthewaterows
smoothly.
3)Ifdrainhoseextensionorembeddeddrainpipingisrequired,useappropriatepartsthatmatchthehosefrontend.

4)Whenextendingthedrainhose,useacommerciallyavailable
extensionhosewithaninnerdiameterof16mm.
Besuretothermallyinsulatetheindoorsectionoftheextension
hose.

Refrigerant Piping Work
1. Flaring the pipe end
1)Cutthepipeendwithapipecutter.
2)Removeburrswiththecutsurfacefacingdownward
sothatthechipsdonotenterthepipe.
3)Putthearenutonthepipe.
4)Flarethepipe.
5)Checkthatthearingisproperlymade.
Set exactly at the position shown below.

Check
Flare’s inner

be flaw-free.
The pipe end must
be evenly flared in
a perfect circle.
Make sure that the
flare nut is fitted.
WARNING
•Donotusemineraloilonaredpart.
•Preventmineraloilfromgettingintothesystemasthiswouldreducethelifetimeoftheunits.
•Neverusepipingwhichhasbeenusedforpreviousinstallations.Onlyusepartswhicharedeliveredwiththeunit.
•DoneverinstalladriertothisR410Aunitinordertoguaranteeitslifetime.
•Thedryingmaterialmaydissolveanddamagethesystem.
•Incompletearingmaycauserefrigerantgasleakage.
