7.15 End of washing operations

With reference to Figure 17

• Stop the machine using the line button (Fig. 17/A)

• Switch off the wall-mounted main switch (Fig. 17/B)

• Open the doors, making sure they are firmly hooked to their supports. (Fig. 17/C)

• Remove the horizontal filters, being particularly careful so as not to drop residues of food inside the washing tank. (Fig. 17/D)

• Lift the vertical filter and dispose of its contents. Use a hard brush to rinse the horizontal and the vertical filters. (Fig. 17/D)

• Wearing latex or rubber gloves, pull out the overflow and allow the wash tank to empty. (Fig. 17/F)

• Accurately wash the bottom of the tank with a jet of water.

• Accurately wash the curtains.

• Remove any traces of dirt from the empty tank. At this point only, remove the safety filter of the pump and wash it under running water. (Fig. 17/G)

• The external parts of the machine must be cleaned when their surfaces are cool, using a sponge and non-foaming products that must be neither acid nor abrasive.

• Reinsert the overflow devices, the safety filters and the tray filters. The machine is now ready to use.

WARNING: Do not wash the machine with water streams or high-pressure water directly applied to

it, as any leaks into the electric components may compromise the regular function of the machine and of its safety systems, annulling the warranty. It is advisable to leave the doors open, to avoid the formation of unpleasant smells.DISHWASHER INSTRUCTIONS MANUAL Page 30 of 33 MDITT31-(r07)

7.16 Positioning the dishes

With reference to figures 14,15 and 16

• This dishwasher is designed for washing plates, glasses, flatware, kitchen utensils, trays and small containers, always using specific 50x50 cm baskets which must be correctly loaded.

• Place cups and glasses upside down in the flat baskets. Stem glasses must only be washed in baskets with dividers which can be purchased separately fig. 14

• Place plates in the plate basket specifically designed with support shafts, with the inner surface facing upwards fig.14.

• Place flatware and teaspoons in the cutlery basket with the handles pointing downwards. Wash the various types together for optimum wash results fig.14.

• Trays and chopping boards of a maximum size of 530x325x60 mm (gastronorm 1/1) may be washed, using specific baskets without sides and inserts, loading them lengthwise in the direction of machine travel fig.14 and 15 Recommendations:

• Do not wash silver and stainless steel flatware in the same cutlery basket as this will tarnish the silver and may corrode the stainless steel.

• Always use the specific baskets designed for the various types of item to be washed (plates, glasses, cups, flatware, trays etc.) fig. 14.

• To save both detergent and electricity, only wash full, but not overloaded, baskets.

• Avoid overlapping items.

• To minimise maintenance, we recommend pre-cleaning items to be washed by removing left-over food particles such as fruit peel plus toothpicks, olive pits etc, which could otherwise partly clog the filter of the electro-pump, reducing wash performance and negatively affecting the quality of the final results fig.14.

• It is advisable to wash the dishes before food particles dry onto the surface. In the event of dried-on food residue, dishes and flatware should be left to soak before being put in the machine

• Always select the wash programme and/or speed best suited to the type of items to be washed

• Always wash glasses with clean wash water and, if possible, at the start of the shift or after changing the water. Use the glasses cycle available on some models.

• To wash crystal glassware, only use baskets with special compartments and water with conductivity below 80 µS

• If a corner configuration pre-wash is present, the trays must be loaded with any protruding parts facing the direction of travel Fig.16

• The machine is not designed for the continuous washing of predominantly large-sized items. The latter may nonetheless be washed, in between the washing of other dishes and using suitable baskets with tray supports.

• The machine is not designed for washing baskets.

• Incorrect loading or washing of large-sized items, for which the machine is not designed, may lead to abnormal leaks into the drain, resulting in the partial emptying of the tanks. In this case, the machine stops automatically and proceeds to refill with water until the correct level is restored. This may occur several times over the course of service.

• The baskets must be of a type suitable for the dishwasher's conveyor system and must be in good condition, especially on the bottom. Use the baskets in the machine's equipment as a reference.

• In the case of machines with corner configuration drying, trays must be placed in the dedicated basket, leaving one out as illustrated in figure 15

• Baskets sized 50x60 cm cannot be used.DISHWASHER INSTRUCTIONS MANUAL MDITT31-(r07) Page 31 of 33

The machines are designed to minimise the need for maintenance. Carefully observe the rules below to ensure the long working life of the machine and trouble-free operation. In any case, there are a few general rules to follow to keep the machine in perfect working order:

• keep the machine clean and tidy

• avoid allowing temporary or urgent repairs to become a matter of routine Strict observance of routine maintenance rules is extremely important; all machine parts must be regularly checked to prevent problems and malfunctions from arising, thus reducing the time required for any maintenance interventions. Warning!

• Before cleaning operations, disconnect the appliance from the power supply

• Before cleaning, wear gloves with a minimum cut protection of 3 in accordance with EN388.

• Cleaning the machine with products that contain chlorides in a concentration exceeding 50 ppm can lead to corrosion of the machine's stainless steel structure.DISHWASHER INSTRUCTIONS MANUAL Page 32 of 33 MDITT31-(r07)

With reference to Figure 18 Attention! Before carrying out the following operations, wear gloves with a minimum cut protection of 3 in accordance with EN388.

• Disassemble the upper and lower rinsing arms.

• Clean all nozzles, removing any obstruction found, and reassemble them.

• Disassemble the curtains and clean them with a nylon brush under running water.

• Disassemble the upper and lower washing arms and rinse them.

• Remove the washing pump filter and rinse it.

• Clean the washing tank thoroughly.

• Due to the calcium and magnesium salts present in the water, after a certain period of operation, which varies according to the hardness of the water used, a calcareous layer deposits in the inner surfaces of the boiler tank and of the pipes, compromising the proper functioning of the machine.

• It is therefore necessary to periodically remove incrustations, an operation that should be carried out by technically qualified personnel.

• If the machine is to be left unused for a long period of time, the steel surfaces must be greased with Vaseline oil.

• If there is danger of water freezing, have technically qualified personnel drain the boiler water and the washing pump water.

• If intense calcareous deposits form inside the machine in the presence of water, use an incrustation removing product.

• To remove the incrustations, carefully follow the instructions of the manufacturer of the product, or seek the assistance of qualified personnel. In any case, always rinse the machine thoroughly after removing incrustations.

• Make sure the safety devices are working efficiently.

• If the steam condensing battery is dirty, disassemble it and clean the spaces between the flaps using compressed air.

• REMINDERS: Every mechanical and electromechanical part of the machine is subject to physical wear. A qualified technician must carry out periodical inspections on: - Conveying system sledges - Washing/rinsing electro-pump seals - Door guides and springs - Remote control switch - Safety devices In addition, it is obligatory to test and inspect the devices that are not part of the machine, such as earthing differential, proper earthing, automatic switches and/or fuses in the power line, every electric conductor, the status of water pipes, discharge system, proper functioning of dispensers.

• In case of malfunctioning, seek only technical assistance centres authorised by the manufacturer or by the manufacturer's dealer.DISHWASHER INSTRUCTIONS MANUAL MDITT31-(r07) Page 33 of 33
