EN
The following sounds that are generated by the appliance during operation are a
normal phenomenon and do not indicate any malfunctions.
– Splashing, bubbling and hums are generated by the coolant that
circulates the system.
– Short, louder whirring/hooting or clicking sounds may be heard when the
compressor of the appliance starts.
Alarms and prompts
In the case of the alarm, the proper prompt flashes on the digital display,
interchangeably with the temperature value; also, the buzzer and the alarm replay
(if available) may be activated.
All alarms go off automatically (i.e. alarm prompt is stopped, when the cause for the
alarm is eliminated; only the 'CHt' alarm must be confirmed manually through
switching off and on again of the appliance with the use of
button or
disconnection from the mains supply).
When pressed, the
button switches off the buzzer; but the displayed alarm
code and the alarm relay are deactivated only when the cause of the alarm is
eliminated. The available alarm codes are listed in Table 3 below.
