*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 flow selector unit and the dedicated cooling circuit.
*3: Select the branch pipe of the first 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 AP056 (6 hp) for the first circuit after the header branch.
When using a branch header for the first branch with an outdoor unit capacity code of 33.5 (12 hp equivalent) or more and 73.0 (26 hp
equivalent) or less, use RBM-HY2043FE (4 branches) and RBM-HY-2083FE (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 first branch if the performance rank is over 73.0 (26 hp
equivalent).
*6: The downstream starting point is the main pipe.
*7: Only group operation with one remote controller (or two remote controllers) is possible if one flow selector unit is connected to multiple
indoor units.
