Translation of original Operating and Installation Instructions

 

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, dangers 
may occur during their use which may lead to injuries to the user or 
others, or to 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 all personnel have read and understood the Oper-
ating 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 and read and observe the safety 
data sheets. 

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

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 especially applies to parts contaminated with toxic 
substances. 

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

Ensure that the old appliance is disposed of in an envi-
ronmentally-appropriate manner. Use appropriate waste 
collection systems for the disposal of end-of-life equip-
ment. Used pumps contain valuable recyclable materials.
