Before wiring, confirm the rated voltage of the unit as shown on its nameplate, then carry out the wiring closely following
the wiring diagram.

(3)
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 10-16 A, having a contact separation in all poles.
To prevent possible hazards from insulation failure, the unit must be grounded.
Each wiring connection must be done in accordance with the wiring system diagram.
Wrong wiring may cause the unit to misoperate or become damaged.
Do not allow wiring to touch the refrigerant tubing, compressor, or any moving parts of the fan.
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.
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.
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 designated by the manufacturer,
because special-purpose tools are required.

Wiring System Diagrams
<Type E2>
(1) Refer to “Recommended Wire Length and Wire
Diameter for Power Supply System” for the explanation
of “B”, “C”, “D” and “E” in the above diagram.
(2) The basic connection diagram of the indoor unit shows
the terminal boards, so the terminal boards in your
equipment may differ from the diagram.
(3) Refrigerant Circuit (R.C.) address should be set before
turning the power on.
(4) Regarding R.C. address setting, refer to the installation
instructions supplied with the outdoor unit. Auto address
setting can be executed by remote controller automatically.
Refer to the installation instructions supplied with the
remote controller (optional).
