3.3. Disassembly and assembly of the pump
The disassembly should only be performed by qualified personnel.
Each operation carried out on the machine must always be carried out once all the electrical
contacts have been disconnected. The pump-motor unit must be placed in a position where
it cannot be started unintentionally.
Before servicing in any way the parts that come in contact with the pumped liquid, make
sure that the pump has been fully emptied and washed. When draining the liquid, make
sure that there is no danger for people or the environment.
The numbers put in brackets, refer to the part numbers in the spare part drawings and spare
part lists in chapter
