DANGER
NOTICE
à
Establish normal atmospheric pressure in the lines while
the pump is at a standstill (relieve pump pneumatically).
Connecting the pump
A marking on the pump head indicates the flow direction.
1. Remove the protective caps from the pneumatic connec-
tions of the pump.
2. Mount suction filter or silencer accessory parts (if
present).
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 3 Tech-
nical data [} 13]) with the
medium.
Excessive pressure, with all of the as-
sociated hazards, can be prevented by
means of a bypass line with a pressure
relief valve between the pressure side
and suction side of the pump. Further
information is available from KNF Cus-
tomer Service (contact data: see
