the set will drop and cause injury.

8. For electrical work, follow the local national wiring standard, regulation and the installation instruction. An independent circuit and single outlet

must be used. If electrical circuit capacity is not enough or defect found in electrical work, it will cause electrical shock or fire.

9. This equipment is strongly recommended to install with Earth Leakage Circuit Breaker (ELCB) or Residual Current Device (RCD). Otherwise, it

may cause electrical shock and fire in case equipment breakdown or insulation breakdown.

10. Do not use joint cable for indoor / outdoor connection cable. Use the specified Indoor/Outdoor connection cable, refer to installation instruction

CONNECT THE CABLE TO THE INDOOR UNIT and connect tightly for indoor / outdoor connection. Clamp the cable so that no external force will be acted on the terminal. If connecting or fixing is not perfect, it will cause heat up or fire at the connection.

11. Wire routing must be properly arranged so that control board cover is fixed properly. If control board cover is not fixed perfectly, it will cause

heat-up or fire at the connection point of terminal, fire or electrical shock.

12. When install or relocate air conditioner, do not let any substance other than the specified refrigerant, eg. air etc. mix into refrigeration

cycle (piping). (Mixing of air etc. will cause abnormal high pressure in refrigeration cycle and result in explosion, injury etc.).

13. Do not install outdoor unit near handrail of veranda. When installing air-conditioner unit at veranda of high rise building, child may climb up to

outdoor unit and cross over the handrail and causing accident.

14. This equipment must be properly earthed. Earth line must not be connected to gas pipe, water pipe, earth of lightning rod and

telephone. Otherwise, it may cause electric shock in case equipment breakdown or insulation breakdown.

15. Keep away from small children, the thin film may cling to nose and mouth and prevent breathing.

16. Do not use unspecified cord, modified cord, joint cord or extension cord for power supply cord. Do not share the single outlet with

other electrical appliances. Poor contact, poor insulation or over current will cause electrical shock or fire.

17. Tighten the flare nut with torque wrench according to specified method. If the flare nut is over-tightened, after a long period, the flare

may break and cause refrigerant gas leakage.

18. During pump down operation, stop the compressor before remove the refrigeration piping. (Removal of compressor while compressor

is operating and valves are opened will cause suck-in of air, abnormal high pressure in refrigeration cycle and result in explosion, injury etc.)

This symbol denotes item that is PROHIBITED from doing.

CAUTION

WARNING
