 Do not store or use flammable gas or

combustible near the product.

There is risk of fire or failure of product.

 Do not use the product in a tightly closed

space for a long time.

Oxygen deficiency could occur.

 When flammable gas leaks, turn off the gas

and open a window for ventilation before turn the product on.

Do not use the telephone or turn switches on or off. There is risk of explosion or fire.

 If strange sounds, or small or smoke comes

from product. Turn the breaker off or disconnect the power supply cable.

There is risk of electric shock or fire.

 Stop operation and close the window in

storm or hurricane. If possible, remove the product from the window before the hurricane

arrives.

There is risk of property damage, failure of product, or electric shock.

 Do not open the inlet grill of the product

during operation. (Do not touch the electrostatic filter, if the unit is so equipped.)

There is risk of physical injury, electric shock, or product failure.

 When the product is soaked (flooded or

submerged), contact an Authorized service center.

There is risk of fire or electric shock.

 Be caution that water could not enter the

product.

There is risk of fire, electric shock, or product damage.

 Ventilate the product from time to time

when operating it together with a stove, etc.
