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.
Insulation’s heat-resistance temperature should be more than 120
℃

Refrigerant pipe before EEV kit and MCU or without EEV kit and MCU
You can contact the gas side and liquid side pipes but the pipes
should not be pressed.
When contacting the gas side and gas side pipe, use 1 grade thicker
insulation.
Refrigerant pipe after EEV kit and MCU
Install the gas side and liquid side pipes, leave 10mm of space.
When contacting the gas side and liquid side pipe, use 1 grade
thicker insulation.
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.
