WARNING
Amputation of limbs due to rotating components!
No persons must be present in the work area of the pump! There is risk of (serious)
injuries due to rotating components! No persons must be present in the work area of
the pump during start-up or operation.
WARNING
Risk of burns from hot surfaces!
Motor housing can become hot during operation. It may cause burns. Allow the
pump to cool down at ambient temperature after switching it off!
When operating the pump, observe the locally applicable regulations on the following
topics:
▪ Workplace safety
▪ Accident prevention
▪ Handling electrical machines
Strictly comply with the personnel responsibilities specified by the operator. All person-
nel are responsible for ensuring compliance with responsibilities and regulations!
Due to their design, centrifugal pumps have rotating parts that are easily accessible.
Depending on operating conditions, sharp edges can develop on these parts. WARN-
ING! This can lead to cuts and limbs may be severed! Check the following at regular
intervals:
▪ Operating voltage (+/-10 % of the rated voltage)
▪ Frequency (+/-2 % of the rated frequency)
▪ Current consumption between individual phases (max. 5 %)
▪ Voltage difference between the individual phases (max. 1 %)
▪ Max. switching frequency
▪ Level control device/dry-running protection: Switching points
▪ All gate valves open
▪ Operation/control: Operating personnel must be instructed in the functioning of the
complete system.
▪ Electrical work: A qualified electrician must carry out the electrical work.
▪ Installation/dismantling: The technician must be trained in the use of the necessary
tools and fixation materials for the relevant construction site.
▪ Locally applicable accident prevention and safety regulations of trade associations.
▪ Observe regulations for working with heavy loads and under suspended loads.
▪ Provide the necessary protective equipment and make sure that the personnel wears it.
▪ Provide adequate aeration in closed rooms.
▪ Take immediate countermeasures if there is a build-up of toxic or suffocating gases!
The pump is deactivated during decommissioning, but remains installed. This ensures
that the pump is always ready for operation.
‡
To protect the pump from frost and ice, always immerse the pump completely in
the fluid.
‡
The temperature of the fluid must always be above +3 °C (+37 °F).
1. Switch off the pump at the operating point.
2. Secure the operating point against being switched on again by unauthorised per-
sons (e.g. lock main switch).
▶ The pump is out of operation and can now be dismantled.
If the pump remains installed after decommissioning, observe the following:
▪ Ensure that the prerequisites for decommissioning are maintained for the complete
period of decommissioning. If these prerequisites cannot be guaranteed, dismantle the
pump after decommissioning!
