injury, and/or product failure.
• Contact an authorized service center when you install or relocate
the air conditioner. Failure to do so may result in serious injury and/
or product failure.
• Indoor/outdoor wiring connections must be secured tightly and the
cable should be routed properly so that there is no force pulling the
cable from the connection terminals. Improper or loose connections
may cause heat generation or fire.
• Install the panel and the cover of the control box safely. Failure to do
so may result in explosion or fire.
• Do not install the air conditioner near a place with a danger of explosion or fire; because it may result in explosion or fire which may
result in serious bodily injury or death.

unit and the outdoor unit are not pulled tight when installing the air
conditioner. Failure to do so may result in electric shock or product
failure.
Usage
• Do not mix air or gas in the system except for the specic refrigerant.
If air enters the refrigerant system, it may result in excessively high
pressure that may lead to personal injury or damage to the equipment.
• Safely dispose of packing materials such as screws, nails or batteries in a packing bag after installation or repair. Failure to do so may
result in serious bodily injury.
