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 cus -
tomer.
The pumps are equipped with a thermal winding cover, if the motor cools down, the pump starts auto-
matically. 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 re-
quirements must be observed.
- Endangerments through electric power must be eliminated (details concerning this, see e.g. the regula-
tions 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 restart, 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 of the machine is only guaranteed, if it is used as intended according to chapter 1 – General. The
limit values stated in the data sheet must not be exceeded.
ATTENTION
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.
