2.Remove burr on the edge of pipe.

-- If burr is not removed after cutting the pipe, there is a risk of refrigerant gas leakage.

-- If foreign substance such as burr goes into the pipe, there is a risk of product breakdown. Face the pipe downward when doing the work.

When installing, make sure there is no leakage. When recovering the refrigerant, ground the compressor first before

CAUTION 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.
