Do not use unspecified cord, modified cord, joint cord or extension cord for power supply cord. Do not share the single outlet withother electrical appliances. Poor contact, poor insulation or over current will cause electrical shock or fire.3. Do not tie up the power supply cord into a bundle by band. Abnormal temperature rise on power supply cord may happen.4. Do not insert your fingers or other objects into the unit, high speed rotating fan may cause injury.5. Do not sit or step on the unit, you may fall down accidentally.6. Keep plastic bag (packaging material) away from small children, it may cling to nose and mouth and prevent breathing.7. When installing or relocating air conditioner, do not let any substance other than the specified refrigerant, eg. air etc mix intorefrigeration cycle (piping). Mixing of air etc. will cause abnormal high pressure in refrigeration cycle and result in explosion, injury etc.8. Do not add or replace refrigerant other than specified type. It may cause product damage, burst and injury etc.9.For R410A model, use piping, flare nut and tools which is specified for R410A refrigerant. Using of existing (R22) piping, flare nut and toolsmay cause abnormally high pressure in the refrigerant cycle (piping), and possibly result in explosion and injury.Thickness for copper pipes used with R410A must be more than 0.8 mm. Never use copper pipes thinner than 0.8 mm.It is desirable that the amount of residual oil less than 40 mg/10 m.10. Engage authorized dealer or specialist for installation. If installation done by the user is incorrect, it will cause water leakage, electricalshock or fire.11. Install according to this installation instructions strictly. If installation is defective, it will cause water leakage, electrical shock or fire.12. Use the attached accessories parts and specified parts for installation. Otherwise, it will cause the set to fall, water leakage, fire or electricalshock.13. Install at a strong and firm location which is able to withstand weight of the set. If the strength is not enough or installation is not properlydone, the set will drop and cause injury.14.

Wire routing must be properly arranged so that control board cover is fixed properly. If control board cover is not fixed perfectly, it will causefire or electrical shock.17. 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.18.During installation, install the refrigerant piping properly before running the compressor. Operation of compressor without fixing refrigerationpiping and valves at opened position will cause suck-in of air, abnormal high pressure in refrigeration cycle and result in explosion, injuryetc.19.During pump down operation, stop the compressor before removing the refrigeration piping. Removal of refrigeration piping whilecompressor is operating and valves are opened will cause suck-in of air, abnormal high pressure in refrigeration cycle and result inexplosion, injury etc.This symbol denotes item that is PROHIBITED from doing.
