REFNET Pipe System
Installation of Outdoor Units
57
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.
When field piping is connected to the B section of the inlet/outlet pipe on the outdoor unit side of the liquid pipe
header.
Cut the B section with a pipe cutter as shown below and connect it to the A section.
Connect the flared section of the field pipe to the B section.
Fit the branch pipe so that the branch lies in a horizontal plane.
The branch pipe must be insulated in accordance with the instruction manual which comes with each kit.
1. Use the insulator included in the kit to insulate the header.
2. Joints between insulators included in the kit and those already applied to the field piping should be sealed with the
tape which is also included in each kit.
3. Any cap pipes should also be insulated using the insulator provided with each kit and then taped as described above.
