Test results
Q: How does the integrated dry-running protection work?
A: It automatically restarts 3 minutes after shut down.
Q: How does the integrated dry-running protection work?
A: It prevents sand from damaging the pump.
Q: How does the integrated dry-running protection work?
A: It automatically shuts down the pump if water shortage is detected.

Q: By how much does the supply voltage decrease before the motor contactor stops the pump?
A: More than 10 %
Q: By how much does the supply voltage decrease before the motor contactor stops the pump?
A: More than 15 %
Q: By how much does the supply voltage decrease before the motor contactor stops the pump?
A: More than 20 %
Q: Why is it important to protect the pump from over- and under voltage?
A: Because large variations in power supply will damage the motor over time.
Q: Why is it important to protect the pump from over- and under voltage?
A: To avoid burning the house fuses.
Q: Why is it important to protect the pump from over- and under voltage?
A: To minimise the power consumption.
