Page 14: Set-Up
CW/CWH – 511 MDA 5 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 warewasher is first installed to customise it to the user's requirements. To modify the parameters, proceed as follows. 5.1 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 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. 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) 5.3 Parameter programming procedure ... -

Press the pump‐out button for about 2”, the LED flashes and the pump‐out and automatic tank cleaning phase starts. When pump‐out is complete the appliance switches to “OFF” status. (only 2 digits lit on the display) 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 5.8. 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 5.8 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 ...
