Caution:
Batteries may explode or leak if they are opened or incinerated. Consider
disposal directions!
Battery maintenance:
To accurately balance the battery capacity a cyclical battery maintenance is necessary.
The pump asks the user to perform a battery maintenance every 30 days. The battery
maintenance mode detects a possible capacity loss (e.g. through ageing of the battery
pack) and then the capacity/running time will be calculated anew. After a longer
storage time or a longer operation without battery maintenance it can happen that
the battery pre-alarm time can no longer be maintained. In this case it is necessary to
perform a battery maintenance.
To initiate the discharge process the message „Battery maintenance“ and the
k
-key
will be displayed after switching the pump off. By pressing
k
and
u
the discharge
process will start. The process is interrupted by switching the pump on again. IIf the
battery maintenance is to be continued a new activation is necessary. After completely
discharging the battery it will be completely charged again. The total duration of the
battery maintenance process takes approx. twelve hours.
Caution:
Please take into account that, if the battery maintenance has not been
completed there is a possibility of a reduced battery operating time.
