7. PIPE INSTALLATION-2

Installing insulation
• Determine the thickness of the insulation material by referring to Table A.
Table A, Selection of insulation
(for using an insulation material with equal heat transmission rate or below
0.040 W/(m·k))
Relative humidity
[mm (in.)]
9.52 (3/8)
Pipe diameter
15.88 (5/8)
• If the ambient temperature and relative humidity exceed 32 °C, increase the level of
heat insulation for the refrigerant pipes.

8. TEST RUN

Always turn on the power 12 hours prior to the start of the operation in order to ensure
compressor protection.
Make a TEST RUN in accordance with the installation instruction sheet for the indoor unit.
