• Ensure that the branch pipes are attached horizontally or vertically (see the diagram below.)
• There is no limitation on the joint mounting configuration.
• If the diameter of the refrigerant piping selected by the procedures described is different from the size
of the joint, the connecting section should be cut with a pipe cutter.
• Branch pipe should be insulated with the insulator in each kit.
• When the number of pipes to be connected is
smaller than the number of header branches,
install a cap to the unconnected branches.
• The indoor unit having larger capacity must be
installed closer to
than smaller one.
• If the diameter of the refrigerant piping selected
by the procedures described is different from
the size of the joint,
the connecting section
should be cut with a pipe cutter.
