Select 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 a standard of the indoor tem-
perature of 27°C and humidity of 80%.
If installing in an unfavorable conditions, use thicker one.
Insulation's heat-resistance temperature should be more than 120℃.

should not be pressed.
When contacting the gas side and gas side pipe, use 1 grade thicker
insulation.

Liquid pipe
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
