5 Select the insulation of the refrigerant pipe.
 Insulate the gas side and liquid side pipe referring to the thickness
 Indoor temperature of 30°C and humidity of 85% is the standard condition.
 Insulator's heat-resistance temperature should be more than 120°C.

<Geological condition>
- High humidity places such as shoreline, hot spring, near lake or river, and
<Operation purpose condition>
- Restaurant ceiling, sauna, swimming pool etc.
<Building construction condition>
- The ceiling frequently exposed to moisture and cooling is not covered.
- The place where the pipe is installed is highly humid due to the lack of
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

If installing 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.
