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.
1. 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 airflow 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. preserving precision devices,
food, pets, plants, and art objects). Such usage could damage the items.
1. Do not touch the metal parts of the unit when removing the filter. Injuries can occur when handling
sharp metal edges.
2. Do not use water to clean inside the air conditioner. Exposure to water can destroy the insulation,
