Warning:
• The unit should not be installed by the user. Ask the dealer or an authorized company to install the unit. If the unit is installed improperly,
water leakage, electric shock or fire may result.
• Do not stand on, or place any items on the unit.
• Do not splash water over the unit and do not touch the unit with wet hands. An electric shock may result.
• Do not spray combustible gas close to the unit. Fire may result.
• Do not place a gas heater or any other open-flame appliance where it will be exposed to the air discharged from the unit. Incomplete
combustion may result.
• Ventilate the room if refrigerant leaks during operation.
If the refrigerant comes in contact with a flame, poisonous gases will be released.
• Do not remove the front panel or the fan guard from the outdoor unit when it is running.You could be injured if you touch rotating, hot or
high-voltage parts.
• Never insert fingers, sticks etc. into the intakes or outlets, otherwise injury may result, since the fan inside the unit rotates at high speed.
• If you detect odd smells, stop using the unit, turn off the power switch and consult your dealer.
• This air conditioner is NOT intended for use by children or infirm persons without supervision.
• Young children should be supervised to ensure that they do not play with the air conditioner.
Caution:
• Do not use any sharp object to push the buttons, as this may damage the remote controller.
• Never block or cover the indoor or outdoor unit’s intakes or outlets.
Disposing of the unit
When you need to dispose of the unit, consult your dealer. If pipes are removed incorrectly, refrigerant (fluorocarbon gas) may blow out and come into
contact with your skin, causing injury. Releasing refrigerant into the atmosphere also damages the environment.
