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.
Density
Dimension change route by heat
Water absorption rate
Thermal conductivity
Moisture transpiration factor
Moisture transpiration grade
Formaldehyde dispersion
Oxygen rate

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.
