Appliance cleaning
This function makes it easy for the shop’s sta to carry out a cleaning of the appliance according to a standard
procedure. Appliance cleaning is activated via a pulse signal – as a rule via a key switch placed on the appliance or
via the AK-CC55 Connect mobile app.
Appliance cleaning is carried out via three activations:
At the rst activation, the refrigeration is stopped, but the fans keep on operating in order to defrost the
evaporators. ”Fan” is shown on the display.
At the second activation, the fans are also stopped and the appliance can now be cleaned. ”OFF” is shown on the
display.
At the third activation, refrigeration is recommenced. The display will show the actual appliance temperature,
o97 setting.
When appliance cleaning is activated, a cleaning alarm is transmitted to the normal alarm recipient. A later
processing of these alarms will document that the appliance has been cleaned as often as planned.
There are no temperature alarms during appliance cleaning.
