• When installing, make sure there is no leakage. When collecting the refrigerant, stop 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 which may
lead to explosion and injury.
