2.5 Cleaning
2.5.1 Cleaning Scheduler
The control system built into the appliance includes a cleaning scheduler that continually
records the operating hours of the appliance. When a pre-defined number of operating hours
has elapsed, an alert is triggered to indicate that a scheduled clean is due. The ‘Display
Active Alarms’ key will flash red. When the ‘Display Active Alarms’ key is pressed, a cleaning
alert screen will be displayed to indicate the remaining time for a clean to be completed. A
typical example of a cleaning alert message is shown in Figure 21.
The appliance must be cleaned within 6 days of the first alert; otherwise it will shut down.
When all steps of the cleaning procedure described in Section 2.5.3 have been completed in
full, the appliance will return to normal operation and the cleaning scheduler will be
automatically reset.
