11.10 Built-in protection

The motor incorporates an electronic unit which
protects the motor in various situations.
In case of overload, the built-in overload protection
stops the pump for 5 minutes. After that period, the
pump is ready to restart if the start conditions are
fulfilled.
To reset the pump, switch off the power supply for 1
minute.
The motor is protected in the following situations:
• Dry running.
• Voltage surges (up to 6000 V) in areas with high
lightning intensity. External lightning protection is
required.
• Overvoltage.
• Undervoltage.
• Overload.
• Overtemperature.

11.11 Contaminated pumps

Warning
If a pump has been used for a liquid which
is injurious to health or toxic, the pump will
be classified as contaminated.
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.
However, any application for service, no matter to
whom it may be made, must include details about the
pumped liquid if the pump has been used for liquids
which are injurious to health or toxic.
Before a pump is returned, it must be cleaned in the
best possible way.
