8.6 Repairs

Warning
The pump housing must only be opened
by personnel authorised by Grundfos!
Repairs must only be carried out by
authorised and qualified personnel!
Switch off the pump and disconnect it from
the voltage supply before carrying out
maintenance work and repairs!

Note

The replacement of the supply cable must
be carried out by an authorised Grundfos
service workshop.

After consulting Grundfos, please send the pump,
together with the safety declaration completed by a
specialist, to Grundfos. The safety declaration can be
found at the end of these instructions. It must be
copied, completed and attached to the pump.

Caution

The pump must be cleaned prior to
