3.  Safety 

 

Observe the safety precautions in Chapters  
6. Installation and connection and 7. Operation. 

 

The pumps are built according to the generally recognised rules of 
technology and in accordance with the pertinent occupational 
safety and accident prevention regulations. Nevertheless, potential 
dangers during use can result in injuries to the user or others, or in 
damage to the pump or other property. 

Only use the pumps when they are in a good technical and proper 
working order, in accordance with their intended use, observing the 
safety advice within the Operating and Installation Instructions, at 
all times. 

Make sure that only trained and instructed personnel or specially 
trained personnel work on the pumps. This especially applies to 
assembly, connection and servicing work. 

Make sure that the personnel has read and understood the Operat-
ing and Installation Instructions, and in particular the "Safety" 
chapter. 

Always ensure adherence to all pertinent accident prevention and 
safety regulations when working on and operating the pump. 

When transferring dangerous media, observe the safety regula-
tions for handling such media. 

Always ensure adherence to all information stickers on the pumps, 
such as flow direction arrows and type plates, and keep stickers in 
a legible condition. 

All replacement parts should be properly stored and disposed of in 
accordance with the applicable environmental protection regula-
tions. Ensure adherence to the pertinent national and international 
regulations. This applies especially to parts contaminated with toxic 
substances. 

Dispose of all packaging in an environmentally-appropriate 
manner. The packaging materials are recyclable. 

Dispose of end-of-life equipment in an environmentally 
friendly manner. Use appropriate waste collection systems 
for the disposal of end-of-life equipment. Used pumps 
contain valuable recyclable materials.
