REFRIGERANT PIPING WORKS
• The piping length between the outdoor unit and the indoor unit may not exceed the allowable piping length.
• The pressure of the R410A is high. Use only certified refrigerant pipe and follow the installation method.
• Use clean refrigerant pipe which there is no harmful ion, oxide, dust, iron content or moisture inside pipe.
• Use tools and accessories fit on R410A.

Select the main pipe of outdoor units with the following
table.
Select the main pipe of outdoor units with the following table
when if the farthest indoor unit’s length is over 90m(295').
• 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.
