30 Instructions for use 4.2 Using the machine DIN is a German standard which describes how the washing process must work in rack conveyor or flight type machines in order to ensure good washing results. Amongst other things, it recommends that the contact time should be around 120 seconds for normally soiled loads. The contact time is the time which the load spends in a wash or rinse zone with washing water containing detergent. In principle this means the period from when the load enters the pre-wash zone to when it is rinsed with clean water in the final rinse zone. The standard is a useful means of comparing the capacity and consumption of different dishwashers Washing Numbers in brackets refer to the pictures in the chapter entitled "The machine s design". Before trays are fed into the machine, they must be soaked to remove dried-on pieces of food. Push in the trays on the long side first through the feed opening. The belt and the washing process will start. For the movement of trays through the machine to continue, new trays must be fed in all the time. For each tray that is fed in, the belt moves just one short step and then stops. The next tray that is fed in will start the belt again. When no more trays are fed into the machine, it will stop Storage in the tray dispenser If washed trays are stored in the tray dispenser connected to the machine's outfeed end, a message will appear on the display when the dispenser is full of trays. Change the dispenser. When an empty dispenser is put in place, the machine is ready to wash again. The machine can also be connected to a tray exchanger for two dispensers. When one dispenser is full, the trays are automatically switched to the other and the machine does not stop until both dispensers are full Changing the water Numbers in brackets refer to the pictures in the chapter entitled "The machine s design". For best wash results, it is important that the water in the tanks is changed if it becomes too dirty. The water should always be changed if foam begins to form in the chemical wash tank. Switch the machine off by pressing button (10). Remove the filters (19) and empty the machine by turning the level pipe (22) a quarter of a turn. When the tank is empty, close the level pipe and refit the filters. Refill the machine with water. 26
