Refrigerant Piping Work
With a multi indoor unit
, install as described in the installation manual supplied with the Multi outdoor unit.

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.
•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.
