INSULATING THE REFRIGERANT PIPE
Insulating the refrigerant
• You must check if there is a gas leak before completing all the installation process.
• Use EPDM insulation which meets the following condition.
Selecting the insulation of the refrigerant pipe
• Insulate the gas pipe and liquid pipe by referring to the thickness of insulator for each pipe size.
• The standard condition is 30°C, less than humidity 85%. If the condition is in high humidity, use
one grade thicker.
Insulating the refrigerant pipe
• Be sure to insulate the refrigerant pipe, joints and connections with class ‘o’ material.
• If you insulate the pipes, the condensed water does not fall from the pipes and the capacity
of the air conditioner is improved.
• Check if there are any insulation cracks on the bent pipe.
