5. 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.

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.
 W hen contacting the gas side and gas side pipe, use 1 grade thicker
insulator.
Refrigerant pipe after EEV kit and MCU
 Install the gas side and liquid side pipes, leave 10mm of space.
 W hen contacting the gas side and liquid side pipe, use 1 grade
thicker insulation.
• I nstall the insulation not to get wider and use the adhesives on the connection part of it to
prevent moisture from entering.
• W ind the refrigerant pipe with insulation tape
if it is exposed to outside sunlight.
• I nstall the refrigerant pipe respecting that the
insulation does not get thinner on the bent
part or hanger of pipe.
