Before Operation

1. Contact an installation specialist for installation.

2. Plug in the power plug properly.

3. Use a dedicated circuit.

4. Do not use an extension cord.

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.
