Refrigerant piping work
1. Cut the pipe with a pipe cutter ensuring that the cut edge remains flat and then remove all the burrs.
2. Make sure that the flared pipe doesn't have uneven thickness, damaged and cracked surfaces, or any other defects.
3. You must use torque wrench when connecting pipes or flare nut.
❶
• When installing, make sure there is no leakage. When collecting the refrigerant, stop the compressor first before
removing the connection pipe.
WARNING
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 which may lead to
explosion and injury.
