4. ELECTRICAL WIRING

4-1. General Precautions on Wiring

(1) Before wiring, confirm the rated voltage of the unit as shown on its nameplate, then carry out the wiring closely following the
wiring diagram.
WARNING
(2) This equipment is strongly recommended to be installed with Earth Leakage Circuit Breaker (ELCB) or Residual Current Device
(RCD). Otherwise, it may cause electrical shock and fire in case of equipment breakdown or insulation breakdown.
Earth Leakage Circuit Breaker (ELCB) must be incorporated in the fixed wiring in accordance with the wiring regulations. The
Earth Leakage Circuit Breaker (ELCB) must be an approved 15 A, having a contact separation in all poles.
(3) To prevent possible hazards from insulation failure, the unit must be grounded.
(4) Each wiring connection must be done in accordance with the wiring system diagram. Wrong wiring may cause the unit to misoperate or
become damaged.
(5) Do not allow wiring to touch the refrigerant tubing, compressor, or any moving parts of the fan.
(6) Unauthorized changes in the internal wiring can be very dangerous. The manufacturer will accept no responsibility for any damage or
misoperation that occurs as a result of such unauthorized changes.
(7) Regulations on wire diameters differ from locality to locality. For field wiring rules, please refer to your LOCAL ELECTRICAL CODES before
beginning.
You must ensure that installation complies with all relevant rules and regulations.
(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 single side.
(9) If the power supply cord of this appliance is damaged, it must be replaced by a repair shop designated by the manufacturer, because special-
purpose tools are required.

Type
(1) The power supply inlet is located at the lower area of the
refrigerant tubing side of the unit. The electrical component box
is located at the air intake of the bottom of the unit.
(2) Before installing the ceiling panel, be sure to carry out the
wiring connection.
(3) Remove the lid located on the bottom of the indoor unit
attaching the electrical component box by unscrewing the
Phillips head tapping screws (×2).

(4) Lead the wires from the power supply inlet to the unit. Be sure
to lead the wires through the power supply inlet. Make sure that
no wire is caught between the indoor unit and ceiling panel.
Otherwise, the unit may cause a fire.
(5) Connect the wires into the terminals through the power supply
inlet for the electrical component box.
Fix the wires with a clamping clip.
(6) Reinstall the lid of the electrical component box in its original
position with paying attention not to have the wires caught in
the lid.
