2.Bend the connection pipe to an appropriate length using a bender depending upon the installation place.
3.Perform pipe bending process.
4.Connect the high pressure pipe (ø6.35mm) and low pressure pipe (ø15.88mm) to the high/low pressure pipe of the outdoor unit and tightening by applying appropriate torque.
ffFlare process
1) Cut the pipe using the pipe cutter. | 90° |
