The appliance may only be connectedto an electrical supply which has beeninstalled in accordance with IEC 60364. The appliance may only be connectedto alternating current. The voltage mustcorrespond with the type plate on theappliance. The minimum fuse rating required at thesocket outlet is 13 A (slow-blow). To avoid accidents due to electricalfaults we recommend the use of sock-ets with a line-side current-limiting cir-cuit breaker (max. 30 mA nominaltripping current). The plug and coupling of the extensioncable used must be watertight. Always fully unroll electrical cables fromthe cable drum. This appliance was designed to beused with detergents which are sup-plied or recommended by the manufac-turer.
