5. Selecting the insulation for the refrigerant pipes.
X
Insulate the gas side and liquid side pipe referring to the thickness according to the pipe size.
X
The thickness according to the pipe size is a standard of the indoor temperature of 27 °C and humidity of 80 %.
If installing in an unfavorable conditions, use thicker one.
X
Insulator’s heat-resistance temperature should be more than 120 °C.
