DANGER! Risk of fatal injury!
Incorrect installation and improper electrical connections can be
life-threatening.
• Have the electrical connections established by approved electri-
cians only, in compliance with the applicable regulations!
• Adhere to regulations for accident prevention.
DANGER! Risk of fatal injury!
Failure to install safety devices on the motor, terminal box or on
the coupling can cause electrical shock or contact with rotating
parts, potentially resulting in life-threatening injuries.
• Before commissioning and after maintenance work, all safety
devices (such as terminal box covers or coupling covers) that were
removed must be reinstalled.
• Keep a safe distance during commissioning.
• Always wear protective clothing, protective gloves and protective
goggles when working.
WARNING! Risk of injury due to the weight of the pump!
The pump itself and pump parts can be extremely heavy. Falling
parts pose a risk of cuts, crush injuries, bruises or impacts, which
may lead to death.
• Always use suitable lifting equipment and secure parts against fall-
ing.
• When performing installation and maintenance work, protect the
pump components against falling.
• Never stand underneath a suspended load.
CAUTION! Risk of material damage!
Danger of damage due to incorrect handling.
• Have the pump installed by qualified personnel only.
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.
• A minimum flow of approximately 10 % of the maximum flow rate
must be ensured at all times.
