Selecting the insulator of the refrigerant pipe
ffInsulate the gas pipe and liquid pipe by referring to the thickness of insulator for each pipe size.
ffThe standard condition for indoor temperature is 30°C with humidity less than 85%. If the condition is out of this standard condition, use the pipe that is one grade thicker.
Pipe diameter (mm) | Minimum thickness of the insulator | Remarks | ||

| • Make sure to install the insulation so that there is no gap or crack and use the adhesives on the connection part of it |
CAUTION | to prevent moisture from entering. |
• Wind the refrigerant pipe with insulation tape if it is exposed to outside sunlight. (When winding the insulation | |
| tape, make sure that the thickness of the insulator does not get any thinner.) |
| • Install the refrigerant pipe respecting that the insulation does not get thinner on the bent part or hanger of pipe. |
| • If the thickness of the insulation gets thinner, use additional insulation. |
