[. . . ] € • • Read this “INSTALLATION GUIDE” before operating. [. . . ] If the water inlet hose is not already installed, it must be screwd to the appliance. € The appliance must not be connected to the mixing tap of an un-pressurized water heater. € Check water-tightness of connections by turning the tap completely on. € If the hose is too short, replace it with a suitable length of pressure resistant hose (1000 kPa min, EN 50084 approved type). € Check the inlet hose regularly for brittleness and cracks and replace if necessary. For models with Water Stop hose: If the flexible hose is too short, replace it with a 3 m Water Stop hose (available from AfterSales Service or from your dealer). Depending on the model, the inlet hose and the plastic enclosure at the tap connection contain electrical components. Do not cut the hose and do not immerse the plastic enclosure in water. [. . . ] Electrical connections must be made in accordance with local regulations. [. . . ]
