If the dynamic pressure exceeds the limit stated in the technical characteristics, a pressure reducer must be installed. Connect the water intake hose to a connector with ¾” gas threaded fitting, inserting the filter provided. Only use new hoses for connection to the water supply. If the water supply system has been unused for a long time, run the water to flush the air and dirt from the pipes. For models with a water softener, an approved double check valve must be fitted at the point of connection. For models without a water softener, an approved single check valve must be fitted at the point of connection. Drain connection The dishwasher is fitted with a drain pump and can operate with drain connections on the floor or wall. When connecting the dishwasher's drain hose, avoid kinks, sharp bends, or crushing. The drain connection must be made in accordance with the relevant national regulations.
Page 14: Connection to the electricity supply The dishwasher must be connected to the electrical system by authorised, skilled staff, in accordance with the relevant regulations. A circuit breaker with contact gap rated for category II overvoltage and an overcurrent protection device must be installed in an easily accessible position on the dishwasher's power supply line. The electrical protection devices must undergo a functional test before the dishwasher is put into operation. If the dishwasher is connected to the electrical mains by means of a plug, it must be of the same type as the power socket and compliant with the relevant national regulations. Electrical safety is only ensured if the dishwasher is connected to an earth conductor compliant with the relevant electrical regulations. Do not connect the dishwasher to the electrical mains by means of adapters or extensions, since they may cause dangerous overheating. Connect the appliance to the equipotential bonding system. The dishwasher is always powered up unless the master switch is turned off or the plug is disconnected.
Page 15: First start-up The electrical protection system must undergo a functional test before the appliance is put into operation. The appliance must be installed and/or inspected by qualified staff, who will start it up for the first time and provide the relevant operating instructions. Preparing for use The rinse aid dispenser is fitted on all models, the detergent dispenser only on some. If both dispensers are present, put the external detergent and rinse aid containers in place and insert the respective intake hoses. Whenever the type of detergent or rinse aid is changed, it is essential to flush out the peristaltic pumps. Always use only products specifically recommended for use in a professional dishwasher. Replacement of the internal tube of the detergent and rinse aid peristaltic pumps is recommended every 12 months or 15,000 wash cycles. Using the water softener The dishwasher is equipped with an automatic water softener which removes substances that cause hardness from the water. A litre of water must be poured into the tank with the salt the first time the dishwasher is used. The mixture of water and detergent must not get into the salt tank, as this would impair operation of the regeneration system.
Page 16: Control panel features include the on-off button, program selection button, and start confirm/pause button. The total emptying button is for the tank and boiler. An additional function selection button is also present. Light indicators include mains power on light, dishwasher operation light, and malfunction light. The pump-out in progress light and symbols for no rinse-aid and no salt are included. The tank heating element on symbol and boiler element on symbol are also part of the control panel. The instructions apply to both undercounter and hood-type dishwashers. Some sections may refer to procedures specific to one type or the other, depending on the model purchased. Green light indicates the dishwasher is ready, blue light shows operation in progress, and red light signals a malfunction.
Page 17: When the display control panel is switched on, it shows the type of dishwasher and the firmware version. If the dishwasher is already powered up, press the on/off button for direct display of the firmware version. During first start-up, certain functions and parameters must be set or adjusted. The dishwasher parameter modification procedure begins with the tank empty. To access the main PCB setup menu, press and hold the button for 5 to 7 seconds. All modifiable parameters can be displayed and scrolled through with the button. Press the button to select the required value for each parameter. To confirm the value, either quit the menu or move on to the next parameter. Quitting the setup menu automatically occurs after about 3 minutes of inactivity. In manual mode, hold the ON/OFF button until the beep sounds to switch off the dishwasher.
Page 18: Modifiable parameters The illustrations are purely guideline. The minimum and maximum temperatures available depend on the model. Rinsing temperature (boiler temperature) Washing temperature (tank temperature) Warning: The tank and boiler temperatures shown on the display may be different from the actual temperatures by a few degrees. Adjusting rinse aid dispensing (optional if installed) Every time the button is pressed, the value increases of 0.1 g/l up to a max of 2 g/l. Default: 1.2 g/l. Adjusting detergent dispensing (optional if installed) Every time the button is pressed, the value increases of 0.2 g/l up to a max of 20 g/l. Default: 2.6 g/l. Auto start function Set at “on” to start the cycle when the hood/door is closed. Set at “off” to start the cycle after confirmation with the start button.
Page 19: Regeneration frequency setup (models with softener) At first use, the salt tank has to be filled. It is subsequently sufficient simply to fill up with regenerating salt when necessary. Mains water hardness setting table With values over 60°f an external water treatment device must be used and the regeneration frequency must be set on H00. Extra rinse Rinsing is 10” longer than the standard in each washing cycle. Clean water cycle When this option is activated, the appliance pumps out all the water from the tank and then refills it with clean water at every wash cycle. Prolonged use of this option leads to higher detergent and rinse aid consumption.
Page 20: Thermostop settings determine the minimum rinsing temperature based on the boiler temperature. When set to on, the cycle duration may be slightly longer than nominal. Setting off may result in a lower minimum rinsing temperature if hot intake water is not used. Users must ensure minimum temperatures are maintained if the thermostop is off. It is important to check the intake water temperature. Refer to the troubleshooting section for issues related to washing, drying, or foam in the tank. Fast start (FST) allows the dishwasher to start in less than standard time, increasing water consumption. Eco start (ECO) begins the dishwasher in standard time without additional water consumption. The cycles performed counter tracks the total cycles since installation and cannot be reset without software reprogramming. USER program is the only customizable program, allowing duration adjustments through setup parameters.
Page 21: Service setting (for after-sales service only) Accessing the technical set-up menu. Refer to the specific technical documentation. Starting the peristaltic pumps – rapid filling of detergent and rinse aid delivery circuit. Perform after the parameter modification procedure explained in the previous point. With the dishwasher powered up and the tank full, press the on/off button for a few seconds. The peristaltic pumps continue to operate until the same button is pressed again. The rinse aid and detergent symbol lights flash alternately as long as the pumps are on. The rinse aid peristaltic pump fills the circuit in about 7 minutes, while for the detergent it only takes 2 minutes. Draw only rinse aid from the jerry cans for the first 5 minutes and then also take in detergent for the last 2. To reset the message, open the dishwasher door and close it again.
Page 22: Malfunctions shown on the display for the technician. The dishwasher can identify several malfunctions and display them. If the problem persists after restarting the dishwasher, follow the outlined procedures. Tank temperature probe malfunction (Er 04) indicates a disconnected or faulty probe. Check the water supply tap, dynamic supply pressure, inlet water filter cleanliness, and water charging hose for damage. Tank water filling malfunction (Er 05) may involve leakage from the tube connected to the air trap. Obstructions in the drain pipe and filter cleanliness should be checked. Water pump-out malfunction (Er 06) can occur due to obstructions in the drain pump. Boiler heating element issues may arise from operation without water in the boiler. Boiler temperature probe malfunction (Er 24) indicates a disconnected or faulty probe.
Page 23: - Menu service wrong setting “rP” - Check cleanliness of the rinse nozzles - Faulty boiler pressure switch (it always detects “full”) - Leakage or unbinding of the tube (water runs inside the tube) - Rinsing pump malfunction (if present) - Boiler emptying malfunction - Faulty boiler pressure switch (it always detects “full”) - Check settings in the service menu on entry “rP” - Boiler full signal on models without rinsing pump - “rp” = on for models with rinsing pump, “rp” = off for models without rinsing pump
Page 24: Instructions for the user include details about the control panel and its functions. The on-off button is essential for powering the dishwasher. The program selection button allows users to choose different washing programs. The start confirm/pause button initiates or pauses the washing cycle. The total emptying button is used for draining both the tank and boiler. An additional function selection button provides extra features. The control panel includes various indicator lights: L1 indicates mains power is on. L2 shows the dishwasher's operational status, with blue for washing, green for ready, and red for malfunction. L3 indicates pump-out progress. There are symbols for no rinse-aid, tank heating element, no salt, boiler element on, and no detergent. The instructions apply to both undercounter and hood-type dishwashers, with some procedures specific to the model purchased.
Page 25: Use only detergents and rinse aids for industrial dishwashers. Do not use detergents intended for hand washing. We recommend the use only special products, developed for this dishwasher. When topping up the tanks, take care not to swap the products; this might damage the dishwasher. Do not mix different detergents; this would damage the dispenser device. Failure to comply with this recommendation leads to forfeiture of the warranty entitlement on the appliance’s water system. Industrial dishwasher detergents may cause serious irritation. Comply carefully with the instructions provided by the detergent producer on the pack. Check that the filters are in place, the spray arms rotate, and there are no foreign bodies in the dishwasher. Turn on the mains water tap.
Page 26: First use each day (tank and boiler empty). With the door/hood closed, press and hold it down. The display shows the firmware version and update installed, then the tank and boiler temperatures. This is followed by FILL and the boiler water temperature. The boiler heating element symbol remains lit until heating finishes. Once the water in the boiler has been heated, filling of the tank starts. Wait for P1 - END to appear and light L2 to change from blue to green. Press the button quickly to display the tank and boiler temperatures for a short time. Load the dishes and close the door to start the cycle. Select the program required by pressing the button.
Page 27: Cycle in progress, the progress of the cycle is displayed by vertical bars which illuminate in sequence. At the end of the program “END” flashes. Unload the dishes. When the dishwasher is closed again, the system offers the last program run.
Page 28: Operating anomalies If the door is opened with the cycle in progress, “CLOSE” flashes and the program stops. After closing the door, the program start must be confirmed by pressing and holding it down for 1 second. In the event of a power blackout while the cycle is running, the program stops and restarts automatically from the beginning when the power is restored. Program change With the program started, press and hold it down to interrupt it. Change the program by pressing. Confirm the program start by pressing and holding it down for 1 second. During heating of the water in the boiler and tank with the cycle running, the tank heating element and boiler heating element symbols may appear on the display. The filter is fitted with a sensor which checks that it is properly fitted; if it is not in the correct position, the word “FiLTER” appears on the display.
Page 29: Choosing the program involves scrolling through available options, displaying the program number and duration. The program types include different durations based on the type of dirt, ranging from lightly soiled plates to heavily soiled plates. Cycle duration is guaranteed under specific water intake temperature conditions, referring to the first cycle performed. Repeated cycles may vary in duration based on installation conditions and water temperature. Power blackouts will cause the display to read “t” if the dishwasher is open, keeping the heating element off to prevent burns. Closing the dishwasher will resume heating the water in the tank after a power restoration. The shape and material of the provided baskets depend on the purchased model. Extra baskets can be purchased through After-Sale Service. Images of the baskets are indicative and may vary.
Page 30: Glasses: Place the glasses downwards. Use the dedicated basket for cutlery. Place the cutlery randomly, preferably with the handle downwards. Use caution to avoid injuries due to prongs of forks and blades of knives.
Page 31: Maintenance and cleaning are essential for optimal performance. Regular servicing by an authorized service center is recommended at least once a year. Consumables and parts subject to wear must be replaced with genuine spare parts. The manufacturer accepts no liability for damage due to carelessness or failure to comply with instructions. The dishwasher has IPX4 protection, but direct water jets for cleaning are forbidden. Remove and clean filters regularly to prevent large residues from falling into the sump. Clean away limescale deposits to avoid excessive build-ups. Leave the hood or door ajar when not in use if possible. Use neutral, non-abrasive detergents that do not contain chlorine compounds for cleaning. Avoid using harmful cleaning products near the dishwasher to protect stainless steel surfaces.
Page 32: Cleaning the filter during the day is necessary in heavy-duty working conditions every 30-40 cycles. To clean the filter, carry out the “partial tank pump-out” routine using program “P0”. Press and hold the button until “TANK UNL” and the duration appear on the display. Confirm the action by pressing the button; light L2 turns blue. After cleaning, for undercounter models, press to start filling. For hood-type models, filling starts automatically when the hood is closed. At the end of the day, the dishwasher can perform an automatic cleaning cycle. Press the button to start draining the appliance completely. The indicator L2 becomes blue during the draining process. Never switch off the dishwasher with water in the tank; always pump out first.
Page 33: Topping up with regenerating salt is necessary when the LED indicator lights up. Use only specific salt, not cooking sea salt. The salt container holds about 1 kg of granulated salt. The correct procedure to refill regenerating salt includes starting a tank pump-out, refilling the salt, filling the tank, and restarting the pump-out. Remove any salt residues from the bottom of the tank to prevent corrosion or rust. Routine inspection of the spray arm should be done weekly. Remove the spray arms by unscrewing the central screw and clean the holes and nozzles under running water. Do not use tools that might cause damage to the spray arms. If the dishwasher will be out of use for a long time, empty the detergent and rinse aid dispensers to prevent crystallization. Remove the intake hoses from the containers and place them in clean water, then perform wash cycles followed by a complete pump-out. Turn off the master switch, close the water intake valve, and leave the hood ajar until the interior is dry. When returning to service, ensure the detergent and rinse aid hoses are correctly reconnected.
Page 34: Troubleshooting The dishwasher does not start due to line voltage failure. Verify electricity connection. Wait for the filling process to finish if the dishwasher filling is not over yet. If CLOSE continues to appear on the display even when the dishwasher is closed, contact the after sales service. Dismount and clean the spray arms if CLOSE stays on display. Read “cleaning the filters during the day” for clogged or crusted spray arms holes. Verify detergent type and quantity for insufficient or improper detergent or rinse aid. This ordinary maintenance service is recommended at least once a year for the correct functioning of the dosers. Place dishes/glasses correctly to avoid poor washing results. Increase the duration of the washing cycle if the load is very dirty or partially dried.
Page 35: Verify that the filter of the tube placed inside the rinse aid jerrycan is not clogged. Verify the rinse aid container and if it is adequate to the type of mains water. Inappropriate rinse aid is not dispensed correctly. Verify the boiler set temperature. Restore T Stop ON and/or connect the machine to hot water. If the problem is not solved, contact the After-Sales Service. Water hardness superior to 12°dF or it contains many dissolved salts. Rinse aid unsuitable or not being delivered correctly. Check the container of rinse aid and whether the type is suitable for the mains water. Verify that the tube and drainage are not clogged and that the drainage is not positioned too high.
