pump is returned for service. Otherwise Grundfos can refuse to
accept the pump for service.
Possible costs of returning the pump are paid by the customer.

10.1 SPE
The following is only valid for SPE pump sets.
In case of unintended flow of water through a non-energized
pump there is a risk that the moving parts of the pump and the
motor will start rotating, thereby generating voltage over the
terminals. The size of the voltage depends on the speed of
rotation. Due to this the motor terminals must be considered as
live until proven otherwise.
