• Be careful not to contact connecting wire with piping.
• For the power supply cord and the indoor/outdoor unit connecting wires, be sure to use the ones in compli-
ance with the standards.
• Be sure to push the core until it is hidden and pull each cable to make sure that it is not pulled up incomplete
