(8) To prevent malfunction of the air conditioner caused by electrical noise, care must be taken when wiring as follows:
●
The remote control wiring and the inter-unit control wiring should be wired apart from the inter-unit power wiring.
●
Use shielded wires for inter-unit control wiring between units and ground the shield on both sides.
(9) If the power supply cord of this appliance is damaged, it must be replaced by a repair shop appointed by the manufacturer,
because special purpose tools are required.
