The meaning of eachindication used is as below. Incorrect installation or servicing due to ignoring of the instruction will cause harm or damage, andthe seriousness is classified by the following indications.• The items to be followed are classified by the symbols:• Carry out test running to confirm that no abnormality occurs after the servicing. Then, explain to user the operation, care andmaintenance as stated in instructions. Please remind the customer to keep the operating instructions for future reference.This indication shows the possibility of causing death or serious injury.This indication shows the possibility of causing injury or damage to properties.This symbol denotes item that is PROHIBITTED from doing.1. Engage dealer or specialist for installation and servicing. If installation or servicing done by the user is defective, it will cause water leakage,electrical shock or fire.2. Install according to this installation instructions strictly. If installation is defective, it will cause water leakage, electric shock or fire.3. Use the attached accessories parts and specified parts for installation and servicing. Otherwise, it will cause the set to fall, water leakage, fireor electrical shock.4. Install at a strong and firm location which is able to withstand the set’s weight. If the strength is not enough or installation is not properly done,the set will drop and cause injury.5. For electrical work, follow the local national wiring standard, regulation and the installation instruction. An independent circuit and single outletmust be used. If electrical circuit capacity is not enough or defect found in electrical work, it will cause electrical shock or fire.6. 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.7. Use the specified cable and connect tightly for indoor/outdoor connection. Connect tightly and clamp the cable so that no external force will beacted on the terminal. If connection or fixing is not perfect, it will cause heat-up or fire at the connection.8. Wire routing must be properly arranged so that control board cover is fixed properly. If control board cover is not fixed perfectly, it will causeheat-up or fire at the connection point of terminal, fire or electrical shock.9. When carrying out piping connection, take care not to let air substances other than the specified refrigerant go into refrigeration cycle.Otherwise, it will cause lower capacity, abnormal high pressure in the refrigeration cycle, explosive and injury.10. Do not install outdoor unit near handrail of veranda. When installing air-conditioner unit at veranda of high rise building, child may climb up tooutdoor unit and cross over the handrail and causing accident.11. This equipment must be properly earthed. Earth line must not be connected to gas pipe, water pipe, earth of lightning rod andtelephone. Otherwise, it may cause electric shock in case equipment breakdown or insulation breakdown.12. When connecting the piping, do not allow air or any substances other than the specified refrigerant to enter the refrigeration cycle.Otherwise, this may lower the capacity, cause abnormally high pressure in the refrigeration cycle, and possibly result in explosion andinjury.13. Do not damage or use unspecified power supply cord. Otherwise it will cause fire or electric shock.14. Do not modify the length of the power supply cord or use extension cord, and do not share the single outlet with other electricappliances. Otherwise, it will cause fire or electric shock.15. It is desirable that the amount of residual oil is less than 40 mg/10m.Thickness of copper pipes used with R410A must be more than 0.6 mm. Never use copper pipes thinner than 0.6 mm.16. During installation, before run the compressor, confirm the refrigerant pipes are fixed. Operation of compressor without fixing the piping,setting the valves at open condition, a burst may occur and cause injury.17. After completion of installation or service, confirm there is no leakage or refrigerant gas. It may generate toxic gas when the refrigerantcontacts with fire.18. Ventilate if there is refrigerant gas leakage during operation. It may cause toxic gas when refrigerant contacts with fire.
