[. . . ]  The water hardness has to be between 8° and 14° F (0, 8 - 1, 4 mmol/l). If the water is harder, install a water softener suitable for the water quantity used by the appliance containing 16 litres of resin at least. WARNING: If the appliance works continuously with short cycles, it is necessary to connect the appliance to hot water at 50° C. [. . . ] During the installation, when the Break Tank is empty, switch on the appliance and keep the door open, so that the Break Tank fills up before putting the kitchenware into the appliance. The internal thermostats are set by the manufacturer at the following temperatures:  boiler water temperature: 78 °C;  tank water temperature: 55 °C. 24 WASHING CYCLE  Open the door of the appliance.  Remove all the solid remainders from the kitchen utensils, empty pots and saucepans, and soften any encrustations with specific products.  Place ice cream basins, pots, pans, buckets, saucepans and other kitchenware in the basket with their concave part downwards. Place ladles and similar kitchen utensils in their suitable container provided as standard equipment.  Place baking trays and tins into their suitable stainless steel baskets with their dirty part downwards. A number of different racks for trays are available according to the tray dimensions.  Select the washing cycle:  When switched on, the appliance automatically sets itself to work according to the short washing cycle, suitable for washing not very dirty kitchenware.  In order to select the long washing cycle, push the selector (G); this operation is shown by the turning off of the lamp (H) and the lighting of the lamp (I).  An overflow pipe drains the exceeding water that has been brought in during the rinsing cycle and it enables a continuous change of water in the tank. It also avoids the water overflowing in case of bad working of the pressure switch.  The appliance is equipped with an overflow pipe in the small tank of the Break Tank, too, so that the possibly exceeding water is drained into the wash tank. 25  Power supplies are protected against any accident through a transformer. It is highly recommended to turn off the tap of filling water when the appliance is not working. WARNING MESSAGES If the boiler thermometer (A) or the tank thermometer (C) displays the letter “E”, this is an indication that the thermometer probe is switched off or out of order. If this is the case, make sure that the probe is properly connected to the control panel. It might be necessary to replace the probe. MAINTENANCE Before any cleaning or performing any maintenance always disconnect the appliance from the power supply. [. . . ] This operation is particularly recommended for the good working of the heating elements. 26 It is possible to clean the washing arms simply by removing the plastic plugs placed at their ends. The plugs present a bayonet coupling and they can be easily removed by turning them anticlockwise, as shown on the plug itself. Remove the feeding pipe from the solenoid valves and check their intake filter. If the appliance is not being used for a long time, we highly recommend emptying the pump scroll completely through its plug, even if the pumps installed are self-emptying. [. . . ]
