Protection against overload/thermal motor switch:
The submersible pump is equipped with a thermal motor switch. If the motor overheats,
the motor switch automatically switches off the pump. The cooling time is 25 minutes,
after which the pump automatically switches itself on again. If the motor switch is
switched on, it is absolutely necessary to find and eliminate the cause (see also "Finding
the cause of the problem"). The information provided here may not be seen as
instructions for "home-made" repairs, since the repair work requires specific specialised
knowledge. In case of faults, always contact customer service.
Service and care
Before any kind of maintenance work on the pump is carried out, the electric connection
must always be interrupted (remove the plug from the outlet) to make sure that the pump
is not put in operation. With the exception of the cases described below, the pump must
be sent to customer service if it needs to be repaired. Sand and other abrasive substances
cause premature wear and a reduction in the pump's output. Work on the electrical
components of the pump may only be carried out by customer service (this also applies
for the electric cable and the floater).
The submersible pumps require practically no maintenance. The bearings are self-
lubricating. An occasional cleaning of the filter base with clear water is sufficient, so
that additional maintenance work is not required. The frequency depends on the
environmental conditions. Only original spare parts may be used.
Example of a pump installation in a drain, see fig. 2.
