직사광선을 받지 않는 장소 또는 난방기구(발열체)에서 멀리 떨어진
장소.
인화성 물질(화학약품)이 없는 장소.

2. 설치시 이런점을 주의하십시오.

사용설명서 시스템 연결방법을 완전히 읽으신 후에 연결해 주십시오.

각종 연결선을 완전하게 연결해 주십시오.

(주전원 코드를 뽑은 상태에서 연결.)

불완전한 연결은 잡음, 제품의 손상 또는 안전사고의 원인이 됩니다.

전기적 충격 또는 감전사고의 위험이 있으므로 뚜껑을 열지 말아주십
시오.
주 교류 전원 플러그를 연결하기 전에 사용전압을 확인하신 후 안전
하게 연결하십시오.

제품을 수리시는 규정된 부품과 자격이 있는 사람이 수리를 하여야 함.

The apparatus shall not be exposed to dripping or splashig

and no object filled with liquids, such as vases, shall be

place on the apparatus

이 기계(장치)는 물기에 접촉(물에 적시는 정도의 접촉)해서는 안되며
꽃병과 같은 액체가 담겨진 물체를 기계 가까이 두는것을 금지하여야
합니다.
