Installation Procedure
Insulating the refrigerant pipes and
branch joints
• Check for gas leakage before completing (the hose and pipe
insulation) and if there is no sign of leakage, make sure to
insulate the pipes and hoses.
• Use EPDM material insulator that meets the following
conditions.

Selecting the refrigerant pipe insulator
• Insulate the gas pipe and liquid pipe by referring to the
thickness of insulator for each pipe size.

Insulate the refrigerant pipe
• Make sure to insulate the refrigerant pipe, branch joint,
distribution header, and the connection part of the pipes.
• If you insulate the pipes, condensed water will not fall from the pipes.
• Check if there are any cracks on the insulation at the bent part
of the pipe.
