For gas and liquid branch pipes:
Make sure that all branch pipes are fitted so that they branch either horizontally or vertically.
When the size of the selected field piping is different from that of the branch pipe, the connecting section should be
cut with a pipe cutter as shown in the figure below.
When cutting an inlet or outlet pipe with a pipe cutter, make sure that you make the cut in the center of the
connection area.
You must insulate branch pipes in accordance with the instructions in the accompanying handbook.
