(*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
