3.  Safety 

 

Follow the safety information in Chapter  

6. Installation and connection. 

 

The liquid pulsation damper is built according to the generally 
recognised rules of technology and in accordance with the perti-
nent 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 liquid pulsation damper or 
other property. Only use the liquid pulsation damper in perfect 

working order and in accordance with its intended use. Always 
ensure adherence to the Operating and Installation Instructions 

and work in a safety-conscious manner. 

Make sure that only trained and instructed personnel or specially 
trained personnel work on the liquid pulsation damper. This espe-

cially 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 liquid pulsa-

tion damper. 

When transferring dangerous media, observe the safety regula-

tions for handling such media. 

Always ensure adherence to all information stickers on the liquid 
pulsation damper, 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 liquid pulsation damper is disposed of in 
an environmentally-appropriate manner at the end of its 
useful life. Use appropriate waste collection systems for 
the disposal of end-of-life equipment. Used liquid pulsation 

dampers contain valuable recyclable materials. 

For the purposes of the Machinery Directive 2006/42/EC, liquid 
pulsation dampers ar

e “partly completed machinery", and are 

therefore to be regarded as not ready for use. Partly completed 
machinery may not be commissioned until such time as it has been 
determined that the machine in which the partly completed ma-
chinery is to be assembled conforms to the provisions of Machin-
ery Directive 2006/42/EC. The essential requirements of Annex I of 
Directive 2006/42/EC (general principles) are applied and ob-

served.
