2.3 Dangers in case of non-observance of the safety notes

The non-observance of the safety notes can cause dangers to persons as well as to the environment
and the machine. If the safety notes are not observed, this can result in the loss of all compensation
claims.
In detail, non-observance can for instance result in the following damages as an example:
- Failure of important functions of the pump
- Failure of the prescribed methods for maintenance and repair
- Endangerment of persons through electrical, mechanical and chemical influences
- Endangerment of the environment through leakage of hazardous substances

2.4 Safety-conscious way of working

The safety notes listed in this operation manual, the existent national regulations on accident preven-
tion as well as possible internal working, operating, and safety instructions of the operator must be
observed.

2.5 Safety notes for the operator/user

- Hot or cold device components which could cause danger must be secured against
contact by the customer.
- The pumps are equipped with a thermal winding cover, if the motor cools down, the
pump starts automatically. Due to this fact, the device must be disconnected from
mains during repair or maintenance works!
- Protection against contact with moving parts (e.g. coupling) must not be removed
while the machine is operating.
- Leakages (e.g. of the shaft sealing) of hazardous materials to be conveyed (e.g.
explosive, toxic, hot) must be discharged in such a way that no danger arises for
persons or the environment. The legal requirements must be observed.
- Endangerments through electric power must be eliminated (details concerning this,
see e.g. the regulations of the VDE (German Association for Electrical, Electronic
and Information Technology) and the local energy suppliers).

2.6 Safety notes concerning maintenance, inspection, and assembly works

The operator must make sure that all maintenance, inspection, and assembly works are carried out by
authorised, skilled, and qualified personnel which are adequately informed by having thoroughly stud-
ied the operation manual.
Only use original spare parts.
Generally, works on the machine are only to be carried out when the pump is turned off. The proceed-
ing prescribed in the operation manual in order to stop the pump must be respected at all costs.
Pumps or pump units conveying media dangerous to health must be decontaminated. Immediately
after finalising the works, all safety and protection installations must be reinstalled and/or activated.
Before (re)start, the points listed in the chapter commissioning must be taken into consideration.

2.7 Unauthorised modification and fabrication of spare parts

Retrofitting and modifications of the switching device are permitted only after having consulted the
manufacturer. Original spare parts and accessories authorised by the manufacturer ensure the safety.
The use of other parts can lead to the removal of liability for the resulting damages.

2.8 Unauthorised modes of operation

The operational reliability is only guaranteed, if the level control is used as intended according to chap-
ter 1 – General. The limit values stated in the data sheet must not be exceeded.
ATTENTION
ACHTUNG
Also a device operating automatically such as a submersible pump must
not be operated without supervision for a longer time period. If you
leave the device unattended for a longer time period, please disconnect
it from mains.
