• 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.
Branch pipe Fitting
• When the number of indoor units to be connected to the branch
pipes is less than the number of branch pipes available for
connection then cap pipes should be fitted to the surplus branches.
