Evacuating the connected pipes
The outdoor unit is loaded with sufficient R22 refrigerant .You should evacuate the air in the indoor unit and in the pipe.If air
remains in the refrigerant pipes, it affects the compressor. It may cause reduction of cooling capacity and malfunction.
• W
hen 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.
