Select the insulation of the refrigerant pipe.
• Insulate the gas side and liquid side pipe referring to the thickness according to the pipe size.
• Indoor temperature of 30°C and humidity of 85% is the standard condition.
If install in a high humidity condition,use one grade thicker insulator by referring to the table below.
If installing in an unfavorable conditions, use thicker one.
• Insulator’s heat-resistance temperature should be more than 120°C.

• Install the insulation not to get wider and use the adhesives on the connection part of it to prevent
moisture from entering.
• Wind the refrigerant pipe with insulation tape if it is exposed to outside sunlight.
• Install the refrigerant pipe respecting that the insulation does not get thinner on the bent part or
hanger of pipe.
• Add the additional insulation if the insulation plate gets thinner.
