The pumps are built according to the generally recognized rules of
technology and in accordance with the occupational safety and
accident prevention regulations. Nevertheless, dangers can result
during their use which 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 the personnel has read and understood the Operat-
ing and Installation Instructions, and in particular the "Safety"
chapter.
Observe the accident prevention and safety regulations when
performing any work on the pump and during operation.
When transferring dangerous media, observe the safety regula-
tions when handling these media.
Be aware that the pumps are not designed to be explosion-proof.
Make sure the temperature of the medium is always sufficiently
below the ignition temperature of the medium, to avoid ignition or
explosion. This also applies for unusual operational situations.
Note that the temperature of the medium increases when the pump
compresses the medium.
Hence, make sure the temperature of the medium is sufficiently
below the ignition temperature of the medium, even when it is
compressed to the maximum permissible operating pressure of the
pump.
If necessary, consider any external sources of energy, such as
radiation, that may add heat to the medium.
In case of doubt, consult the KNF customer service.
Store the pump and all accessories in accordance with the envi-
ronmental provisions. Observe national and international regula-
tions. This applies in particular to parts that are contaminated with
toxic substances.
If you no longer need your packaging materials (e.g. for return
shipment or other transport of the device), dispose of them in an
environmentally friendly manner.
Old devices must not be disposed of with household waste. Proper
disposal and recycling helps to protect natural resources and the
environment. The end user is responsible for disposing of old
devices according to national and international regulations. Alter-
