3.1.  Type of copper pipe and insulation material

 CAUTION

Refer to the installation manual for the outdoor unit for 

description of allowable pipe length and height difference.

24,000BTU/h model

6.35mm (1/4in.)

15.88mm (5/8in.)

 CAUTION

Install heat insulation around both the gas and liquid pipes.

Failure to do so may cause water leaks.

Use heat insulation with heat resistance above 248 °F. 

Reverse cycle model only

In addition, if the humidity level at the installation location 

of the refrigerant piping is expected to exceed 70%, install 

heat insulation around the refrigerant piping. If the expected 

humidity level is 70-80%, use heat insulation that is 15 mm 

(19/32 in.) or thicker and if the expected humidity exceeds 

80%, use heat insulation that is 20 mm (25/32 in.) or thicker.

If heat insulation is used that is not as thick as speci

fi

 ed, 

condensation may form on the surface of the insulation. 

In addition, use heat insulation with heat conductivity of 

0.045 W/(m•K) or less (at 68 °F).
