Selecting the insulator of the refrigerant pipe
• 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.

Insulating refrigerant pipe
• 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.

CAUTION
• 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.
