7.4 Hygiene logbook
In the hygiene logbook you can:
 retrieve all operating conditions, actions, and failures for one day in chronological order.
 retrieve all HACCP and hygiene relevant data.
The list starts with the current date and the first event on this day. Then the following events on that day, and
then the events of days before. The most important operating data are summarized at the end of each day.
INFO When the memory capacity is reached, the oldest data is deleted as soon as new data is added.
Accessing the hygiene logbook
 Press the button.
 The hygiene logbook display then appears:
 The list starts with the current date and the first event on this day.
 This is followed by the events from the days before.
 Press the back button to exit from the menu.
7.4.1 Data transfer to PC (option)
Because the hygiene logbook stores only a limited number of entries, there is also the possibility to transfer
the records to a PC and archive them there.

7.5 Descaling / basic cleaning
7.5.1 Descaling programme
If the machine is operated with hard water without water treatment, the boiler, the machine interior, all water
lines and other components may scale.
Grease residues and dirt that remain in the machine can contribute towards an unhygienic interior and can
lead to failure of heating elements. Regular removal of these layers is absolutely essential.
Using the descaling programme you can descale the interior of the dishwasher. The water lines and the
boiler can only be descaled by an authorised service technician.
For descaling, you need an acid-based descaler suitable for commercial dishwashers. We recommend the
Winterhalter Descaler A 70 LS.
Danger
 When handling chemicals, observe the safety precautions and the dosage recommendations
on the packaging.
 Wear protective clothing, protective gloves and protective goggles when handling chemicals.
Ideally, start the descaling programme when the machine is empty and switched off. If the machine is
already prepared for use, it will automatically empty first.
Only with an external detergent dosing device:
Warning
Development of chlorine gas
If you mix active chlorinated detergent and descaler, chlorine gas is produced. Stop the
detergent dosing (e.g. remove the suction tube or switch off the dosing device).
INFO A detergent dosing device built into the machine will be disabled automatically in the descaling
programme.
