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.
3.1.1. SINGLE TYPE INSTALLATION
MODEL
Liquid pipe
18,000BTU/h model 9.52mm (3/8in.)* 15.88mm (5/8in.)*
24,000BTU/h model 9.52mm (3/8in.)* 15.88mm (5/8in.)
* When single type installation, the ADAPTER included outdoor
unit is necessary to connect the indoor unit to the outdoor unit.
3.1.2. MULTI TYPE INSTALLATION
MODEL
Liquid pipe
18,000BTU/h model 6.35mm (1/4in.)
24,000BTU/h model 6.35mm (1/4in.)
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 specifi 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).
