Selecting the insulator of the refrigerant pipe
X
f
Insulate the gas pipe and liquid pipe by referring to the thickness of insulator for each pipe size.

The 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.

If the installation place has high humidity (such as
basement of a building, seaside, near hot spring
or lake etc.) increase the minimum thickness to
next size up for each pipes.

Pipe insulation
- Insulation of the gas and liquid pipes can be in contact with each other but they should not be pressing each other.
- When contacting the gas side and liquid side pipe, use thicker insulation.

• Make sure to install the insulation so that there is no gap or crack 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. (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.
