• Installation/dismantling: The technician must be trained in the
use of the necessary tools and fixation materials.
• Observe national and regional regulations!
• Observe locally applicable accident prevention and safety regu-
lations of professional and trade associations.
• Provide protective equipment and ensure that the protective
equipment is worn by personnel.
• Observe all regulations for working with heavy loads.
DANGER
Danger of death due to lack of protective devices!
Due to missing protective devices of the terminal box or near the coup-
ling/motor, electric shock or contact with rotating parts can lead to life-
threatening injuries.
• Before commissioning, safety devices such as coupling covers that
were removed must be reinstalled!
DANGER
Danger of death from falling parts!
The pump itself and pump parts can have a very high net weight. Falling
parts pose a risk of cuts, crush injuries, bruises or impacts, which can be
fatal.
• Always use suitable lifting accessories and secure parts against falling.
• Never stand below 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
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 run 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.
• Make sure that the volume flow does not fall below the minimum
