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 side and liquid side pipe referring to the thickness according to the pipe size.
• The thickness according to the pipe size is calculated at the indoor temperature of
27°C(80.6°F) and humidity of 80%. If installing in an unfavorable conditions from it,
use thicker one.
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.

If you install the pipe underground, at the
seaside, a spa or on the lake, use thicker one
according to the pipe size.
