INSULATING THE REFRIGERANT PIPE
Insulating the refrigerant
•
You must check if there is a gas leak before completing all the installation process.
•
Use EPDM insulation which meets the following condition.
Selecting the insulator of refrigerant pipe
•
Insulate the gas pipe and liquid pipe by referring to the thickness of insulator for each pipe size.
•
The standard condition is 30°C, less than humidity 85%. If the condition is in high humidity, use
one grade thicker.
