DANGER
Excessive pressure, with all of the associated hazards,
can be prevented by means of a bypass line with a pres-
sure relief valve between the pressure side and suction
side of the pump. Further information is available from
KNF Customer Service (contact data: see
www.knf.com).
à
Establish normal atmospheric pressure in the lines while
the pump is at a standstill (relieve pump pneumatically).
Connecting the pump
1. Remove the protective plugs from the pneumatic connec-
tions of the pump.
2. Mount suction filter or silencer accessory parts (if
present).
For vacuum operation, connect the hose connector (see Fig.
1/5) to the suction side and the silencer (see Fig. 1/4) or your
vacuum system components to the pressure side.
For pressure operation, connect the hose connector to the
pressure side and the silencer or your vacuum system com-
ponents to the suction side.
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 4 Tech-
nical data [} 13]) with the
medium.
