2. Sigurnosna uputstva
To prevent injury or damage, always observe basic safety precautions, including the following:
- Pažljivo pročitajte i slijedite sva uputstva.
- 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.
- Ako uređaj padne u vodu, NEMOJTE reach for it. First, unplug it and then retrieve it. If electrical components get wet, unplug the appliance immediately.
- 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 the 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, NEMOJTE izvucite kabl. Isključite osigurač ili prekidač koji napaja uređaj. Zatim isključite utikač i provjerite ima li vode u utičnici.
- Neophodan je strogi nadzor kada bilo koji uređaj koriste djeca ili u blizini djece.
- Da biste izbjegli povrede, ne dodirujte pokretne dijelove ili vruće dijelove poput grijalica, reflektora,amp sijalice itd.
- 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.
- Ako je neophodan produžni kabl, treba koristiti kabl odgovarajuće klase. Kabl ocijenjen za manje amperes ili vati od snage uređaja može se pregrijati. Treba paziti da kabel rasporedite tako da se ne spotakne ili povuče.
- Ovaj uređaj ima polarizirani utikač (jedna oštrica je šira od druge). Kao sigurnosna karakteristika, ovaj utikač će stati u polariziranu utičnicu samo na jedan način. Ako utikač ne stane u potpunosti u utičnicu, okrenite utikač. Ako i dalje ne odgovara, obratite se kvalificiranom električaru. Nikada nemojte koristiti sa produžnim kablom osim ako se utikač ne može umetnuti do kraja. Ne pokušavajte da uništite ovu sigurnosnu funkciju.
