¶ Do not mistake the polarities of the wiring for group control and central control.
¶ Take the power supply for indoor units separately in units of each outdoor unit.
7 Cautions on electrical work
¶ Regulations on wire diameters differ from locality to locality.
For field wiring rules, please refer to your LOCAL ELECTRICAL CODES before beginning.
You must insure that installation complies with all relevant rules and regulations.
¶ Invariably draw the power from a dedicated branch circuit.
¶ Fasten the power wiring and inter-unit operating wiring with the "code fixtures accompanying the units, and make
sure that they do not contact the refrigerant tubing, valves, etc.
¶ Do the electrical wiring to the outdoor unit by drilling a hole onto the "power connection panel" matching to the
thickness of conduit, using a hole saw. It can be done from both the left / right sides. (eyelet rubber)
¶ After wiring the indoor unit, seal the power intake clearance with the accompanying putty.
¶ Invariably match the wiring of indoor / outdoor units (incorrect wiring will result in damage).
¶ Do not carry the remote controller wiring, inter-unit operating wires, or central control wiring in the same conduit as
the power wiring, or wire them with the same cables, or wire them close to each other.
¶ Use shield wires for remote controller wiring and inter-unit operating wires. And, invariably earth only one side of the
shield wires.
¶ Keep the power cord of air conditioner and inter-unit cables 3m or more way from the main units, antenna, signal
lines, power cord etc. of any TV, radio, stereo, interphone, personal computer, work processor, telephone, etc.
Otherwise, noise may affect them.
