3. Use a dedicated circuit.
4. Do not use an extension cord.
5. Do not start/st:op operation by plugging/unplugging the power cord.
6. If the cord/plug is damaged, replace it with only an authorized replacement
part.
i. Being exposed to direct airflow for an extended period of time could be
hazardous to your health. Do not expose occupants, pets, or plants to direct
ai_low for extended periods of time.
2. Due to the possibility of oxygen deficiency, ventilate the room when used
together with stoves or other heating devices.
3. Do not use this air conditioner for non-specified special purposes (e.g.
preseP¢ing precision devices, food, pets, plants, and art o_ects). Such usage
could damage the items.
1. Do not touch the metal parts of the unit when removing the filter. Injuries can
