NOTE
Because the indoor units run simultaneously, install them within the same room.
For refrigerant tube branches, use the optional distribution joints.
For cautions on the use of the optional distribution joints, be sure to refer to the provided instruction sheet. Also,
be careful to install them in the correct direction (orientation).
