Connection of Refrigerant Piping

When installing, make sure there is no leakage. When recovering the refrigerant, ground the compressor first before removing the connection pipe. If the refrigerant pipe is not properly connected and the compressor works with the service valve open, the pipe inhales the air and it makes the pressure inside of the refrigerant cycle abnormally high. It may cause explosion and injury.

Flare Processing

1. Cut the pipe using the pipe cutter.

2. Insert the flare nut into the pipe, and then perform the flare processing.

Pipe Bending

1.Perform bending of the pipe using the bender which has a specified bending radius.

2.Be sure to take full care to perform bending of the pipe successfully at one time. Bending and unbending the pipe more than twice makes the bending work increasingly difficult.

3.You may use the spring inserted into the gas pipe instead of the bender to bend the pipe.

4.When you bend the pipe using the spring, hold the pipe with both hands to prevent any distortion, and secure a minimum bending radius of more than 100mm.

Tightening of Connection Parts

Align the center of the connection piping, and tighten the flare nut by turning it with hand. Then tighten it again using the torque wrench in the direction as shown in the figure.
