2. Važna sigurnosna uputstva
WARNING: To avoid injury, basic safety precautions should be observed, including the following:
- Read and follow all safety instructions and all important notices on the appliance before using it.
- OPASNOST – To avoid possible electric shock, special care should be taken since water is used in the use of aquarium equipment. For each of the following situations, do not attempt repairs yourself; return the appliance to an authorized service facility for service or discard the appliance.
- If the appliance falls into water, DO NOT reach for it. First, unplug it and then retrieve it. If electrical components get wet, unplug the appliance immediately.
- Ako uređaj pokaže bilo kakav znak nenormalnog curenja vode, odmah ga isključite iz izvora napajanja.
- Pažljivo pregledajte uređaj nakon instalacije. Ne treba ga uključivati ako ima vode na dijelovima koji nisu mokri.
- Nemojte koristiti nijedan uređaj ako ima oštećen kabel ili utikač, ili ako je neispravan ili je pao ili oštećen na bilo koji način.
- To avoid the possibility of the appliance plug or receptacle getting wet, position the aquarium stand and tank to one side of a wall-mounted receptacle to prevent water from dripping onto the receptacle or plug. A "drip loop" should be arranged by the user for each cord connecting an aquarium appliance to a receptacle. The "drip loop" is that part of the cord below the level of the receptacle, or the connector if an extension cord is used, to prevent water from traveling along the cord and coming into contact with the receptacle. If the plug or receptacle does get wet, DO NOT unplug the cord. Disconnect the fuse or circuit breaker that supplies power to the appliance. Then unplug and examine for presence of water in the receptacle.
- Neophodan je strogi nadzor kada bilo koji uređaj koriste djeca ili u blizini djece.
- Da biste izbjegli ozljede, nemojte dodirivati pokretne dijelove ili vruće dijelove kao što su grijači, reflektori, lamp sijalice i slično.
- Uvijek isključite uređaj iz utičnice kada ga ne koristite, prije stavljanja ili skidanja dijelova i prije čišćenja. Nikada ne vucite kabl da biste izvukli utikač iz utičnice. Uhvatite utikač i povucite za isključivanje.
- Nemojte koristiti uređaj za drugu upotrebu osim predviđene. Korištenje dodataka koje nije preporučio ili prodao proizvođač uređaja može uzrokovati nesigurno stanje.
- Nemojte instalirati niti skladištiti uređaj na mjestima gdje će biti izložen vremenskim prilikama ili temperaturama ispod nule.
- Prije upotrebe provjerite je li uređaj sigurno instaliran.
- Pročitajte i obratite pažnju na sve važne napomene na uređaju.
