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 machine/plant
- 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 prevention 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.
- 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 studied the operation manual.
Generally, works on the machine are only to be carried out when the pump is turned off. The proceeding 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 machine 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 chapter 1 –
General. The limit values stated in the data sheet must not be exceeded.
