Befo,_ Operation
1i_ Contact an installation specialist for installation.
This is NOT a d,o-_t-yourself project.
2. Plug in the power plug properly.
3. Use a dedicated circuit.
4. IDo not use an extension cord. Consult a professional installer or electrician.
5. Do not start/stop operation by plugging/unplugging the po,wer cord.
6. If the cord/plug iis damaged, replace it with only an authorized replacement
part.
1. Being exposed tO direct airflow for an extended period o,f time could be
hazardous to your health. Do not expose occupants, pets, or plants to direct
airflow for extended periods of time. in other words, don't sit in the draft.
2. Due to the possibility of oxygen deficiency, ventilate the room when used
together with stoves or other heating devices,
3. IDo not use tlhis air conditioner for non-specified special purposes (e.g.
preserving precision devices, food, pets, plants, and art objects). Such usage
