5.Do not start/stop operation by plugging/ unplugging the power cord.

6.If the cord/plug is damaged, replace it with only an authorized replacement part.

Usage

1.Being exposed to direct airflow for a long time may be hazardous to your health. Do not expose occupants, pets, or plants to direct airflow for a long time.

2.Due to the possibility of oxygen deficiency, ventilate the room when using the appliance together with stoves or other heating devices.

3.Do not use this air conditioner for nonspecified special purpose (e.g. preserving precision devices, food, pets, plants, or art objects). Such use may damage your properties.

Cleaning and Maintenance

1.Do not touch the metal parts of the unit when removing the filter injury may occur.

2.Do not use water to clean inside the air conditioner. Exposure to water can destroy the insulation, leading to electric shock.
