*1: Use the same size as the main pipe if it is larger than the main pipe.
*2: Use a suction gas pipe and a liquid pipe for the two pipes branching downstream from the

ow selector unit and the dedicated cooling circuit.

*3: Select the branch pipe of the

rst branch according to the outdoor capacity code.

*4: Select according to the outdoor unit capacity code if the total of the indoor capacity codes exceeds the outdoor unit capacity code.
*5: It is possible to select up to a maximum capacity code total 16 (6 hp) for each one branch of the branching header.

When using a branch header for the

rst branch with an outdoor unit capacity code of 33.5 (12 hp equivalent) or more and 73.5 (26 hp

equivalent) or less, use RBM-HY2043FE (4 branches) and RBM-HY2083FE (8 branches) regardless of the total value of the capacity
codes of the downstream indoor units. And, a branch header cannot be used as the

rst branch if the performance rank is over 73.5 (26 hp

equivalent).

*6:  The downstream starting point is the main pipe.
*7:  The group connection of the multiple indoor units is possible up to maximum 8 units, and it is possible only within one FS unit.
*8:  The group connection of the multiple indoor units is possible up to 8 units if one remote controller is used, and it is possible up to 7 units if two

remote controllers are used.

The group connection of the multiple indoor units is possible only within one branch or one FS unit.
