During installation, connection and start up, strictly observe the following instructions. The dishwasher must be installed by specialised personnel, in compliance with the safety regulations in force in the place of use, and following the instructions given below. Always wear personal protective equipment to carry out this type of operation. Failure to follow these instructions will void the manufacturer’s warranty on functional performance and/or damage to the machine. If your dishwasher is found to be damaged when unpacked, contact the dealer before using it. The machine must be transported to the installation site on the pallet supplied, using a pallet truck or forklift. The location must be a professional and not a domestic environment, having industrial type wall or floor drains with drain tanks allowing an outflow of at least 3 l/sec. Make sure the floor at the installation site is flat and can take the weight of the machine full of water with a fully loaded rack (+40% of the net weight).

Before installation the machine can be stored in a sheltered and dry place, with temperatures ranging between 5°C and 40°C. At the first installation or after long idle periods it is advisable to manually rotate the wash and rinse pump impeller (rinse pump for PRS versions) to free it from possibly adhering.

4.2 Machine handling

The machine must be handled by qualified personnel who have adequate experience and training regarding: - the applicable safety regulations; - the ability to identify dangerous situations and adopt the appropriate behaviour The packed machine must be unloaded and transported with a forklift truck, making sure to slot the forks in the pallet frontally. Once on the ground, before being taken to the installation site, remove the packaging, lift the machine with the forks between the pallet and base, always in a diagonal and rear position, lift then remove the pallet and position the machine on the ground. Using a pallet truck (suitable for the weight to be lifted - see net weight in the data table), slot the forks under the base of the machine, placing cardboard between the pallet truck and the machine to avoid damaging it. Do not lift the machine too high from the ground during transport and make sure the route is flat and free of any obstructions. Before moving the machine, check the passageway size of doors and the space for steering operations.

To lift the machine safely the pallet truck forks should protrude at least 10 cm on the opposite side of the base. Wear protective gloves and safety shoes before removing the packaging.

4.3 Water connection

The connections must be carried out by qualified personnel in compliance with the laws in force in the place of installation. Make sure the water supply pressure is between 100÷500 kPa dynamic (1÷5 Bar) for the atmospheric boiler version, and between 200÷500 kPa dynamic (2÷5 Bar) for the version with mains pressure boiler. This measurement must be carried out during the first water filling; if the pressure is higher, install a pressure reducer at the source. If the water has a high content of calcium and magnesium salts, with hardness > 20°f, it is advisable to install a water softener. Each machine is supplied with a water filling rubber hose with a 3/4” connection which must be connected to the mains water supply. The inlet water temperature must be between 10°C and 50°C. If the “ES” energy saving system or the “S” water softener are installed, the inlet water temperature must not exceed 25°C. The drainpipe must be connected to room’s main discharge; it is advisable to insert a floor drain siphon. In the version with incorporated drain pump (option), the drainpipe already has an internal siphon (max. drain height H 800 mm).

4.4 Electrical connection

The electrical connection must be carried out by a qualified electrician, in compliance with local regulations. Make sure the equipment is connected to an efficient earthing system and that the line voltage matches that specified on the machine’s data plate. Connect the power cable to an easily accessible 30 mA thermal- magnetic wall circuit breaker with contact gap of at least 3 mm. Make sure the power cable has not been damaged or crushed during handling. If necessary, it must be replaced only by an authorised installer. Do not plug the power cable in before completing installation and fitting the cover panels. The machine must be connected to an equipotential system, connecting the cable in the rear terminal next to the symbol.

4.5 Safety devices installed

The machine has a number of safety devices in place. - The internal wiring has an amperometric thermal relay which stops the wash cycle in case of a pump fault. - A micro magnetic sensor stops the wash cycle in case of accidental opening of the door. - Manual reset thermostats switch off the heating elements in case of overheating of water. - An overflow pipe keeps the tank water level constant. - A safety pressure switch prevents the water inside the machine from exceeding the maximum level. The manufacturer declines any liability for damage or injury resulting from tampering with or the non-use of these devices or due to non-compliance with the above instructions and the electrical safety regulations in force in the country of installation.

7. AUTOMATIC WATER SOFTENER (OPTIONAL)

Optional automatic water softener is available for both machines with electromechanical buttons and those with electronic control panel (with LCD display). The dishwasher is fitted with an automatic water softener whose operation is managed directly by the PCB.

During the first loading, and at each wash cycle, the water entering passes through the water softener reservoir containing ion exchange resins. These combine with calcium and magnesium ions, responsible for limescale residues, and make them inert. Due to gradual saturation the action of the resins tends to weaken over time but can be restored thanks to the addition of saline water. This process is called “regeneration”. Therefore the water softener also has a 1 kg capacity salt container, which must be periodically filled. A sensor checks the salt level and, if insufficient, the message “SALT FINISHED!” is displayed followed by an alarm sound, or the warning light comes on (8 for version with electromechanical buttons. From this stage on, even if the dishwasher is able to operate, the water softener is not treating the water. Due to the action of the water softener, the hardness of the water used for the wash cycles is reduced to about 6-8 °f. To maintain the effectiveness of the resins and to keep the water hardness level constant, the dishwasher carries out a regeneration after a number of wash cycles, established according to the initial water hardness settings(see Table 1). Regeneration lasts 120 seconds and is done at the end of each initial filling and during the wash cycle with the chosen interval. If a wash cycle with a shorter time has been set, during regeneration this will last 120sec + 20sec (rinse); during the 120 seconds, for all the additional time due to regeneration, the display will show the message “SELF REGENERAT“.

The dishwasher with automatic water softener comes with the water softening function already activated and set for a hardness of 25 °f. For this value, regeneration of the resins occurs every 20 cycles in the electromechanical version and 24 cycles in the electronic version. For different hardness values, the frequency of regeneration must be changed as indicated in Table 1. To change the regeneration frequency, request technical assistance. Initial filling of salt in the container: unscrew the cap, fill the container with 2 glasses of hot water, then add 1 kg of kitchen rock salt. Tighten the cap, making sure to remove any residual salt on the outside.

Maintenance of the automatic water softener system consists of filling the salt container whenever the message “SALT FINISHED!” appears on the LCD display, or when the indicator light comes on (in versions with electromechanical buttons). Only use kitchen rock salt: unscrew the cap inside the wash tank and carefully add 1 kg of salt, using the special funnel provided and facilitating the outflow of water contained in the reservoir below. Make sure the salt does not spill, and do not exceed the recommended amount. After adding the salt, add 2 glasses of hot water in order to facilitate the dissolving of salt, clean the gasket, close the cap properly, eliminate any residual salt, remove the overflow pipe, if present and rinse the tank thoroughly. Residual salt that is not removed can cause corrosion of the steel! 8 YELLOW BLINKING SALT FINISHED! SELF REGENERAT. BLUE48

After filling, the dishwasher is ready for normal operation.

DETERGENT FOR HARD WATER

HARD WATER DETERGENT FOR SOFT WATER

DETERGENT FOR SOFT WATER

Before using the machine it is advisable to proceed as indicated in paragraph 6.1 regarding its state. Solid waste must be removed from items before being washed. In case of encrustations, soak items before introducing them. When putting items in the rack supplied, make sure to arrange them so that the dirtiest part receives water from the lower wash arms yet without retaining water inside them. Each time the cycle ends, open the door and wait a few moments to allow the load to dry and cool naturally. Wear protective gloves before touching the load; it may still be very hot. Run a couple of cycles without loading before using the machine for the first time, to clean the inside and ducts of any impurities. It is advisable to change the tank water every 25 washes or twice a day. In machines with electronic display, it is possible to set the number of cycles after which programmed or forced draining is to be carried out. Too high temperatures can cause starch residues to stick to items. Be careful not to touch the heating element inside the tank upon tank draining and removing the overflow pipe, as it may still be very hot. At the end of the self-cleaning cycle, with the tank empty, clean the filters with running water and remove the residuals of dirt with a non-metallic brush. Place the filters and any other utensils back inside the tank and close the door.

9. CARE AND MAINTENANCE

Check the detergent and rinse aid in the respective containers every day. Do not clean the appliance with direct or high-pressure jets of water. Do not use corrosive products such as sodium hypochlorite or acids. If the feed water has a high content of calcium and magnesium salts, it is advisable to carry out regular descaling with appropriate products in the correct doses and concentrations. Rinse thoroughly and dry the internal parts where the descaling product was applied! In the event of prolonged idle periods (several weeks), it is advisable to run the dishwasher with clean water for 3 cycles before starting the wash. Before proceeding, make sure the wash and rinse pump rotate freely. To do this, use a screwdriver in the special slot on the motor shaft (ventilation side). In the electronic version, when the set number of cycles is reached, the display will show the message “SERVICE WARNING” to prompt contacting technical assistance.
