Y-shape branching joint RBM-Y018-SK Indoor unit capacity code (*1): Total < 6.4
RBM-Y037-SK Indoor unit capacity code (*1): 6.4 = Total < 13.2 (*2)
RBM-Y071-SK Indoor unit capacity code (*1): 13.2 = Total < 25.2 (*2)
RBM-Y129-SK Indoor unit capacity code (*1): 25.2 = Total (*2)
4-branching header (*3) RBM-H4037-SK Indoor unit capacity code (*1): Total < 6.4 Max. 4

outdoor unit) RBM-T129-SK
Connecting pipe Corresponding dia. (mm) Quantity
Balancing pipe 9.52 1
Piping at liquid side 12.7 to 22.2 1
Piping at gas side 22.2 to 54.1 1
(*1) Code is determined according to the capacity code of the Indoor units connected.
(*2) If the total capacity code value of Indoor units exceeds that of Outdoor units, apply the capacity code of Outdoor units.
(*3) When using a branch header, Indoor units with a maximum of 6.0 capacity code in total can be connected to each
branch.
NOTE: If the length of the gas pipe exceeds 30m from the 1st branching to an Indoor unit, increase the gas pipe size by
1 size, i.e. MM-U140 = Gas Ø22.2, Liquid Ø9.5
