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 ma-
chine. If the safety notes are not observed, this can result in the loss of all compensation claims.
In detail, the non-observance can for instance result in the following damages:
- 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 are to be observed.

2.5 Safety notes for the operator/user

- Hot or cold machine components which could cause danger have to be secured against contact by the customer.
- Protection against accidental contact for 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) have to be
discharged in such a way that no danger arises for persons or the environment. The legal requirements are to be
observed.
- Endangerments through electric power are to be eliminated (details concerning this, see e.g. the regulations of the
VDE (Association for Electrical, Electronic and Information Technology) and the local energy suppliers).
2.6 Safety notes concerning maintenance, inspection, and assembly works
The operator has to 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 machine is turned off. The procedure of
switching off the machine, which is described in the operation manual, has to be observed at all costs.
Pumps or pump units which convey media that are hazardous to health have to be decontaminated. Immediately
after completion of the works, all safety and protection devices have to be reattached or reactivated.
Before (re)start, the points listed in the chapter initial operation have to be taken into consideration.

2.7 Unauthorised modification of the machine and fabrication of spare parts

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 operation reliability is only guaranteed, if the machine is used as intended according to chapter 1 – General.
The limit values stated in the data sheet must not be exceeded!
