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℃.

 When installing insulation in places and conditions below, use the same
insulation that is used for high humidity conditions.
<Geological condition>
- High humidity places such as shoreline, hot spring, near lake or river, and
ridge (when the part of the building is covered by earth and sand.)
<Operation purpose condition>
- Restaurant ceiling, sauna, swimming pool etc.
<Building construction condition>
- The ceiling frequently exposed to moisture and cooling is not covered.
e.g. The pipe installed at a corridor of a dormitory and studio or near an
exit that opens and closes frequently.
- The place where the pipe is installed is highly humid due to the lack of
ventilation system.
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.
