Page 7: Installation And Positioning
CWG411MDA 3 INSTALLATION AND POSITIONING INSTALLATION and POSITIONING Bring the glasswasher 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. ... -
Page 8: Electrical Connection
CWG411MDA 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 glasswasher. The stated cycle duration applies to appliances supplied with hot water >50°C<60°C If the appliance is supplied with cold water, the cycle duration might increase depending on the intake water temperature. Drainage: The glasswasher 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 appliance and any additional equipment must be connected to the electrical system ... -
Page 9: First Start-Up
CWG411MDA Figure – Appliance electrical system diagram 5 FIRST START-UP 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 10: Using The Water Softener (On Models With This Feature Only)
CWG411MDA Before inserting the hoses into the containers, fit the weights (needed to ensure that they always draw in liquid from the bottoms of the containers) and the filters onto their ends as shown. If the detergent dispenser is not factory‐fitted, it can be retrofitted after ordering the relative kit. As an alternative an external dispenser can be fitted, making the electrical connection by means of an H05 RN‐F 2x0.5 mm electrical cable, which can be laid along the route shown in the TECHNICAL DATA diagram and connected as shown in the wiring diagram supplied with the glasswasher. The dispenser must operate on 230V/50 Hz with maximum power absorption of 15W. Connect to the detergent dispenser outside the glasswasher using the red hose mentioned above. ... - Page 11 CWG411MDA IMPORTANT: 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 glasswasher. 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 and the diaphragm rinse aid pump should be checked. 11 ...

Page 12: Set-Up
CWG411MDA 6 SET-UP Set‐up During first start‐up, the functions/parameters listed below must be set or adjusted: A series of operations can be carried out when the glasswasher is first installed to customise it to the user's requirements. To modify the parameters, proceed as follows. 6.1 Display Contents The two digits provide the following information: Appliance off but powered up: decimal points on Appliance on: Boiler temperature Washing phase: Tank temperature Pause phase: Boiler temperature Rinse phase: Boiler temperature Programming phase: See parameter programming section Error message: See error messages section 6.2 Note on display of temperatures Both the Boiler and the Tank temperatures provide instantaneous readings of the current value picked up by the probe, but due to the thermal inertia of the probe or its seat, wait about 1 minute after the heating element switches off to obtain the real temperature. The effective temperature in the boiler will be 5 ° C above the set P2 (example if set to 80 °, in this temperature it is the detachment of the resistors, to see the true temperature wait 1 '= approximately 85 ° C; if rinse temperature needed 70°C, set P2 65°C) ... -

To change it, press the key of the program required; the light comes on. To confirm hold down for about 2”. The LED starts to flash and the washing cycle starts. ... - Page 21 CWG411MDA After a total pump‐out the filters should be cleaned as described in the relevant point. Never switch the glasswasher off with water in the tank; always pump out first. Models with water softener: if the set number of cycles is reached (see point 6.9. of "Technical Manual"), the appliance automatically performs regeneration after pump‐out. The entire process lasts about 15', after which the appliance switches off automatically. Resin regeneration (for models with water softener) Once the set number of wash cycles is reached (see point 6.9 of “Technical Manual”) the LED above the key flashes. Therefore, if during the working day resin regeneration is RECOMMENDED, follow the procedure described below. Press the key; the LED flashes and the regeneration phase starts. It lasts about 10 minutes, during which time the LED keeps flashing. When the regeneration phase is complete, the appliance switches to “OFF” status (only 2 digits lit on the display). To reuse the appliance, repeat procedure 7.3 Filling up with regenerating salt (for models with water softener) Caution: use only salt for water softener, do not use cooking salt. Salt must be added when the LED underneath the symbol shown in the box on the left lights up. ...

Page 22: Maintenance And Cleaning
CWG411MDA 9 MAINTENANCE AND CLEANING Although no particular scheduled maintenance is required, users are advised to have the glasswasher checked by a specialist technician twice a year. N.B. the manufacturer accepts no liability for wilful damage or damage deriving from carelessness, neglect, failure to comply with instructions, regulations and standards or incorrect connections, which lead to forfeiture of warranty cover. If possible, leave the door ajar when not in use; Clean surfaces thoroughly and often with a damp cloth; use neutral, non‐abrasive detergents which do not use chlorine compounds, which corrode and damage stainless steel. Do not use the products mentioned above even when cleaning the floor underneath or in the vicinity of the glasswasher, to ensure that fumes or drops cannot damage the steel surfaces. The appliance has IPX4 protection but pointing water jets straight at it for cleaning is ... -
