Product damage or personal injury may result due to contact with the air conditioner’s high-speed fan blades. • Do not attempt to repair, dismantle, reinstall or modify the air conditioner yourself as this may result in water leakage, electric shock or fire hazards. • Do not use flammable spray near the air conditioner, or otherwise fire may result. • Do not use a refrigerant other than the one indicated on the outdoor unit (R410A) when installing, moving or repairing. Using other refrigerants may cause trouble or damage to the unit, and personal injury.
Page 5 Read Before Operation CAUTION • Do not place objects that are susceptible to moisture directly beneath the indoor or outdoor units. Under certain conditions, condensation on the main unit or refrigerant pipes, air filter dirt or drain blockage may cause dripping, resulting in fouling or failure of the object concerned. • After prolonged use, check the unit stand and its mounts for damage. If they are left in a damaged condition, the unit may fall and cause injury. • To avoid injury, do not touch the air inlet or aluminium fins of the indoor or outdoor units. • The appliance is not intended for use by unattended young children or infirm persons.

Accidental operation by a child may result in impairment of bodily functions and harm health. • Avoid impacts to the indoor and outdoor units, or otherwise product damage may result. • Do not place flammable items, such as spray cans, within 1m of the air outlet. The spray cans may explode as a result of hot air from the indoor or outdoor units. • Be careful not to let pets urinate on the air conditioner. Urination on the air conditioner may result in electric shocks or fire. • Do not wash the air conditioner with water, as this may result in electric shocks or fire. • Do not place water containers (vases, etc.) above the unit, as this may result in electric shocks or fire hazards if they should topple over. • Do not insert the batteries in the wrong polarity (+/-) orientation as this may result in short circuiting, fire, or battery leakage. • To avoid oxygen depletion, ensure that the room is adequately ventilated if equipment such as a burner is used together with the air conditioner. • Before cleaning, be sure to stop unit operation and turn off the circuit breaker. Otherwise, an electric shock and injury may result. • Only connect the air conditioner to the specified power supply circuit. Power supplies other than the one specified may result in electric shocks, overheating and fires.
