ELECTRICAL CODES before beginning.
You must ensure that installation complies with all
relevant rules and regulations.
(8)
Regulations on wire diameters differ from locality to
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 one side
only.
(9)
it must be replaced by a repair shop appointed by
the manufacturer, because special-purpose tools are
required.
(10)
If the power supply cord of this appliance is damaged,
All wiring used must be Class 1.
