wet.
•Make sure to connect the air conditioner to an exclusive power
supply of the rated voltage, otherwise the unit may break down or

•Do not use this air conditioner for special purposes such as preserv-
ing food, precision instruments, art objects, breeding animals,
growing potted plants, etc.
•Avoid exposing potted plants and animals to the wind of the air
conditioner, since it badly affects the health and growth of them.
•When the air conditioner is operated with a combustion appliance in
the same place, be careful of ventilation to let fresh air enter the
