(*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
fl
ow selector unit
and the dedicated cooling circuit.
(*3): Select the branch pipe of the
fi
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 6 HP for each one branch of the branching
header.
(*6): When using a branch header for the
fi
rst branch with an outdoor unit capacity code of 12 HP or more and
24 HP 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
(*7): The downstream starting point is the main pipe.
(*8): If the pipe size is Ø19.0 or more, use a suitable material as detailed in the Installation Manual.
(*9): When making the liquid pipe of the main pipe a refrigerant saving size, make height difference between
indoor units smaller than 15 m.
In addition, the farthest piping real length will be limited.
(*10): For installation conditions, refer to the precautions of equipment using R32.
(*11): Please contact our sales representative when merging downstream piping of multi port type.
(*12): Group connection of multiple indoor units is possible up to 8 units within one FS unit or SV unit.
