24524(1)_1 56/10/3 7:06 PM Page 1-1 1. Precautions 1-1 Installing the air conditioner ● Users should not install the air conditioner by themselves. Ask the dealer or authorized company to install the air conditioner except the window-type air conditioner in U.S.A and Canada. ● If you don’t install the air conditioner properly, it may cause a fire, a water leakage or an electric shock. ● You must install the air conditioner according to the national wiring regulations and safety regulations.
24524(1)_1 56/10/3 7:06 PM Page 1-2 1-3 During operation(cont.) Do not place any obstacles in front of the air conditioner. Make sure that the air conditioner is well ventilated at all times: Do not place a cloth or other materials over it. Do not insert anything between the airflow blades to prevent damage of the inner fan and consequent injury. Keep children away from the air conditioner. Remove the batteries if you don’t use the remote control for a long time.

24524(1)_1 56/10/3 7:10 PM Page 13-4 14-5 Q & A for Non-trouble Classification Class Description Q The cooling is weak. A When it is hot outside, its cooling capacity decreases due to the increase of the ambient temperature. When the dust filter gets blocked or warm outside air gets in, the cooling capacity will decrease. So, make sure to clean the dust filter frequently, prevent heat loss by closing the doors and insulate the cooling area by using curtains, blinds, shades or window tinting.
