Performing leak test & insulation
5 Select the insulator of the refrigerant pipe.
Insulate the gas side and liquid side pipe referring to the thickness according to the pipe size.
The thickness according to the pipe size is a standard of the indoor temperature of 27°C and
humidity of 80%.
If installing in an unfavorable conditions, use thicker one.
Insulator’s heat-resistance temperature should be more than 120°C.
Refrigerant pipe
You can contact the gas side and liquid side pipes but the
pipes should not be pressed.
When contacting the gas side and gas side pipe, use 1 grade
thicker insulator.
Install the insulation not to get wider 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.
Install the refrigerant pipe respecting that the insulation does not get thinner on the bent part or
hanger of pipe.
Add the additional insulation if the insulation plate gets thinner.
