DANGER
Risk of fatal injury from falling parts!
The pump itself and pump parts can be extremely heavy. Falling parts
pose a risk of cuts, crush injuries, bruises or impacts, which can be fatal.
• Always use suitable lifting equipment and secure parts against falling.
• Never stand underneath a suspended load.
• During storage and transport, as well as before all installation and as-
sembly work, ensure that the pump is in a safe position and standing
securely.
WARNING
Personal injury due to strong magnetic forces!
Opening the motor leads to high, abruptly occurring magnetic forces.
This can lead to serious cuts, crushing injuries and bruises.
• Do not open the motor!
WARNING

Hot surface!

The entire pump can become very hot. There is a risk of burns!
• Allow the pump to cool down before commencing any work!
WARNING
Risk of scalding!
At high fluid temperatures and system pressures, allow the pump to cool
down first and then depressurise the system.
CAUTION
Damage to the pump due to overheating!
The pump must not be allowed to operate dry for more than 1 minute.
Dry running causes a build-up of energy in the pump, which can damage
the shaft, impeller, and mechanical seal.
