The pumps can be serviced at a Grundfos service centre.
If Grundfos is requested to service the pump, Grundfos must be
contacted with details about the pumped liquid, etc. before the
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.

The following is only valid for SPE pump sets.
DANGER
Magnetic field
Death or serious personal injury
- Do not handle the rotor if having a pacemaker.
DANGER
Crushing of hands
Death or serious personal injury
- Keep the rotor surroundings free of magnetic
objects and be careful when placing the rotor on a
magnetic surface.
DANGER
Electric shock
Death or serious personal injury
- Make sure that motor cable ends are not live
before starting work on the product.
- Make sure that the power supply cannot be
accidentally switched on.
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.
