NOTICE
Risk of dangerous gas mixtures during
pump operation
Depending on the medium being trans-
ferred, breakage of the media-contact-
ing components can result in a danger-
ous mixture if the medium mixes with
the air in the compressor housing or
the surroundings.
à
Before using a medium, check the
compatibility of the media-con-
tacting components (see 5 Tech-
nical data [} 24]) with the
medium.
When using a silencer, KNF recom-
mends operating the pump in a safe
environment, e.g., fume cupboard, to
avoid dangers posed by harmful
gases.
