*1 Piping between REFNETs depends on total capacity index of indoor units connected below each REFNET. It cannot exceed piping size of upstream side.
*2 Piping from REFNET to indoor unit depends on the capacity of the connected indoor unit. It cannot exceed piping size of upstream side.
: Standard piping size of VRV III-Q. However, when equivalent piping length between outdoor unit and indoor unit
is 90 m or more, size of main piping must be increased. See the installation manual.
