Page 8: Installation And Positioning
3 INSTALLATION AND POSITIONING INSTALLATION and POSITIONING Bring the dishwasher to the installation site, remove the packaging and check the appliance and components for damage; any damage found must be reported to the transporter in writing. The packaging components (plastic bags, expanded polystyrene, nails, etc.) must not be left within reach of children and pets since they are potentially dangerous.. All packaging materials used are environment‐friendly. They can be kept without constituting any hazard, or may be disposed of at a specialist waste disposal centre. The plastic components suitable for recycling are marked as follows: PE polyethylene: external packaging film, bag containing the instructions, protective bags. PP polypropylene: straps. PS expanded polystyrene: corner guards, top of packaging. Wooden and cardboard components can be disposed of in accordance with the relevant regulations. When the product is decommissioned it must not be dumped in the environment; it must be disposed of in accordance with the relevant regulations. All metal parts are in stainless steel and can be removed. The plastic parts are marked with the symbol identifying the material used. POSITIONING: Caution: the indoor system and premises in which equipment for institutions is installed must comply with the relevant regulations. The manufacturer declines all liability for direct or indirect injury or damage deriving from failure to comply with these regulations. Before installation, check that there are no objects or materials in the vicinity which may be damaged by steam or splashes of washing solution, or that any such items are suitably protected. ... - Page 9 The water pipelines and electricity supply cable lead out of the bottom right‐ hand corner of the appliance. Connect the water intake hose to a connector with ¾” gas threaded fitting, fitting the filter A provided (in models with aquastop, the filter and ring‐nut form a single unit). The connection to the water mains must only be made with new hoses; the use of old or worn hoses is not permitted. The dynamic water supply pressure must be between 2 and 6 bar; if it is higher a pressure reducer must be installed. If the pressure is less than 2.5 bar it might be necessary to fit a special pump on the appliance to ensure optimal performance. Contact the After‐Sales Service. It is essential to fit a main stop tap on the water intake deliver pipeline; the tap must be accessible after installation of the appliance, so do not install it behind the dishwasher. The stated cycle duration applies to appliances supplied with hot water >50°C<60°C If the dishwasher is supplied with cold water, the cycle duration might increase depending on the intake water temperature. ‐ CWH 510 D 9 ...

The dishwasher is fitted with a drain pump and can operate with drain connections on the floor or wall. Refer to the connection diagram for the maximum permitted height of wall drains – (see TECHNICAL DATA) Caution: make sure that the intake and drain hoses are not bent, constricted or crushed after installation. When installing the drain hose to a siphon with valve, the maximum height of the drain outlet is reduced to 600 mm. 4.2 Electrical connection The dishwasher and any additional equipment must be connected to the electrical system ... - Page 11 Key to single‐phase/three‐phase electrical system diagram NTCB Boiler temperature probe NTCV Tank temperature probe SDET Detergent sensor SBRIL Rinse aid sensor SFIL Filter sensor FLMT Flowmeter Salt sensor Door sensor Rinsing pump Washing pump Boiler level pressure switch Boiler safety thermostat Terminal board RFI filter FUSE Mains fuse Boiler contactor Boiler heating element T‐FU Overtemperature fuse THRV Tank safety thermostat Tank heating element Figure – Appliance single‐phase electrical system diagram ‐ CWH 510 D Aquastop solenoid valve Regeneration solenoid valve Brine discharge solenoid valve ...

Page 14: Using The Water Softener (On Models With This Feature Only)
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 (important) 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 on the rear of the appliance into them. ... - Page 15 The first time the dishwasher is used, a litre of water must be poured into the tank with the salt. Whenever the tank is filled, always take care to ensure that the cap is firmly closed. The mixture of water and detergent must not get into the salt tank, as this would impair operation of the regeneration system. In this case warranty cover will be forfeited. Whenever the type of detergent or rinse aid is changed, it is ABSOLUTELY ESSENTIAL to flush out the peristaltic pumps by placing the external intake pipes in water for a few cycles. Always use only products specifically recommended for use in a dishwasher. Failure to comply with this recommendation leads to forfeiture of the warranty entitlement on the appliance’s water system. The internal pipes of the detergent and rinse aid pumps should be replaced by the After‐Sales Service every 12 months or 15,000 wash cycles and operation of the diaphragm rinse aid pump ...

Clean the outside of the appliance with a damp cloth and neutral soap, rinsing and drying thoroughly. 8.3 Lengthy periods out of use If the dishwasher is to be out of use for a fairly long period of time, the detergent and rinse aid dispenser devices must be emptied to prevent crystallisation and damage to the pumps: remove the intake hoses from the detergent and rinse aid containers and place them in a container of clean water, then perform a few wash cycles followed by a complete pump‐out. Finally, turn off the master switch, close the water intake valve and leave the door ajar until the interior is completely dry. The detergent and rinse aid intake hoses must be put back into the containers when the dishwasher is returned to service, taking care not to swap them over (red hose = detergent, blue hose = rinse aid). 9 TROUBLESHOOTING How to deal with any problems without calling the after‐sales service ... - Page 29 PROBLEM INADEQUATE RINSING STAINS ON GLASSES AND CUTLERY WATER IN TANK AFTER PUMP‐OUT DISHES NOT PROPERLY DRIED ‐ CWH 510 D POSSIBLE CAUSE Dynamic pressure of mains water insufficient Spray arm nozzles fouled Limescale in boiler Rinse aid unsuitable or not being delivered correctly.
