2. 중요 안전 지침
화재, 감전 또는 부상의 위험을 줄이려면 항상 다음의 기본 예방 조치를 따르세요.
- 가습기를 사용하기 전에 모든 지침을 읽으십시오.
- 가습기는 항상 벽과 가전제품에서 최소 12인치(30cm) 떨어진 단단하고 평평하며 방수가 되는 표면에 놓으세요.
- 가습기를 스토브, 라디에이터와 같은 열원이나 직사광선 근처에 두지 마십시오.
- 가습기를 채우거나, 청소하거나, 옮기기 전에 전원 콘센트에서 플러그를 뽑으세요.
- Do not immerse the power cord, plug, or the main humidification unit in water or other liquids.
- Prevent water from entering the power hole and the internal chip. The humidification unit contains sensitive electronic components; do not put it upside down or soak it in water to clean it.
- Ensure the connection between the humidification unit and the water bucket is secure using the elastic buckle to prevent the unit from floating.
- 어린이와 애완동물의 손이 닿지 않는 곳에 보관하세요.
- Use only clean, cool tap water. Distilled water is recommended to minimize mineral buildup.
