Inspections and Maintenance
Apart from cases described below, the pump should be sent to the customer servicing for repair.
Sand and other abrasive materials cause premature wear and decrease the pump performance. Any work on the pump electric parts
should be done by a customer service only (the same applies to electrical cable and float). The dirty water submersible pumps do not
require any maintenance actually. The bearings are self-lubricating. Sufficient is occasional cleaning of the filter base and no other
maintenance is required. In any case, only genuine spare parts should be used.

Inspections and Maintenance Safety Instructions
Before any maintenance of the pump, stop the electric current supply (unplug) and make sure that the pump is not being put in
operation.
Only a unit maintained and cared for on a regular basis may be a serviceable aid. Insufficient maintenance and care may result in
emergencies and unforeseen accidents.
