ACHTUNG
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
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.
-
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
studied 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
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 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
chapter 1 – General. The limit values stated in the data sheet must not be exceeded.
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.
