Be caution when unpacking and installing the product. Sharp edges could cause injury, be especially careful of the case edges and the fins on the condenser and evaporator. 1. Precaution 1.1 Safety Precaution For installation, always contact the dealer or an authorized service center. Do not install the product on a defective installation stand. Be sure the installation area does not deteriorate with age.
If strange sounds or smoke comes from product, turn the breaker off or disconnect the power supply cable. There is risk of electric shock or fire. Install the drain hose to ensure that water is drained away properly. A bad connection may cause water leakage. Keep level even when installing the product. It can avoid vibration of water leakage. Stop operation and close the window in storm or hurricane. If possible, remove the product from the window before the hurricane arrives.
Do not insert hands or other objects through air inlet or outlet while the product is operated. Do not drink the water drained from the product. Use a firm stool or ladder when cleaning or maintaining the product. Be careful and avoid personal injury. Replace the all batteries in the remote control with new ones of the same type. Do not mix old and new batteries or different types of batteries. There is risk of fire or explosion. Do not recharge or disassemble the batteries.
