[. . . ] The mixture of water and detergent must not get into the salt tank, as this would impair operation of the regeneration system. 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 warewasher. 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 AfterSales Service every 12 months or 15, 000 wash cycles and operation of the diaphragm rinse aid pump should be checked. 14 NW511 5 SET-UP Setup During first startup, the functions/parameters listed below must be set or adjusted: A series of operations can be carried out when the warewasher is first installed to customise it to the user's requirements. 5. 1 Display Contents The two green digits provide the following information: Appliance off but powered up: all decimal points on both digits 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 5. 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 power absorption reading to obtain the real temperature. 5. 3 Parameter programming procedure To access the programming menu, proceed as follows: 1) switch the appliance off with the (On Off) key 2) Within 6 seconds, press key P1 (SHORT wash) 7 times. Wait for the 6 seconds to pass; at the end P0 appears on the display 3) Use key P1 to select the parameter to be modified 4) Press the PUMPOUT KEY to display the parameter for modification 5) Modify the parameter by pressing key P1 6) Confirm the change by pressing the PUMPOUT key 7) Select the other parameters for modification in the same way and proceed as described above 8) After setting all the appliance parameters, press the On Off key to quit. 15 5. 4 Modifiable parameters NW511 This table lists the model choice or cycle and temperature option parameters.

(on some models only ) Adjustments are made using the adjuster screw AS SHOWN. The quantity dispensed is reduced by turning anticlockwise and increased by turning clockwise. RB: Rinse aid dispensing regulator screw Adjustments are made using the adjuster screw AS SHOWN. The quantity dispensed is reduced by turning clockwise and increased by turning anticlockwise. It is recommended that periodic monitoring of detergent and rinse aid dispensing; every 15. 000 cycles suggested replace the inner peristaltic pipe 17 NW511 5. 7 Adjusting the regeneration frequency (models with softener only) 5. 8 Memorisation procedure To access the programming menu, proceed as follows: 1) switch the appliance off by pressing the On Off key 2) Hold down the and keys simultaneously for 6 seconds; H0 appears on the display 3) Use the key to modify the parameter; H0, H1, H2, H3, H4, H5 and H0 will appear on the display in cyclic sequence 4) Press the On Off key to confirm the change and quit programming mode. With values over 60°dF an external water treatment device must be used and the regeneration frequency must be set at H00 5. 9 Table of parameters This table shows the relationship between the intake water hardness and the quantity the resins are able to treat; regeneration is required once the appliance has performed the set number of cycles.

[. . . ] Plates/glasses badly arranged Low washing temperature Check electrical mains connection. Remove spray arms and clean them (9. 2 Periodic checks) See "Cleaning the filter during the day" Check type and quantity of detergent. Check temperature shown on the display, call the aftersales service if less than 50°C Increase wash cycle duration, especially if dirt has dried on. If you are unable to solve the problem, call the aftersales service. [. . . ]
