When installing air-conditioner unit on veranda of a high rise building, childmay climb up to outdoor unit and cross over the handrail causing an accident.3. 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.4. Do not tie up the power supply cord into a bundle by band. Abnormal temperature rise on power supply cord may happen.5. Do not insert your fingers or other objects into the unit, high speed rotating fan may cause injury.6. Do not sit or step on the unit, you may fall down accidentally.7. Keep plastic bag (packaging material) away from small children, it may cling to nose and mouth and prevent breathing.8.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, injuryetc.9. Do not pierce or burn as the appliance is pressurized. Do not expose the appliance to heat, flame, sparks, or other sources ofignition. Else, it may explode and cause injury or death.10. Do not add or replace refrigerant other than specified type.
