EDUS371705A-N REFNET Pipe System REFNET Joints and Headers 4.2.1 REFNET Joints For gas and liquid branch pipes Make sure that all branch pipes are fitted such that they branch either horizontally or vertically. When the size of the selected field piping is different from that of branch pipe then the connecting section should be cut with a pipe cutter as shown in the figure below. - Page 10 REFNET Pipe System EDUS371705A-N 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. When the size of the selected field piping is different from that of branch pipe then the connecting section should be cut with a pipe cutter as shown in the figure below.
