Connecting the pump
CAUTION
Risk of injury from mixing up suction side and
pressure side
Mixing up the suction side and pressure side can
result in breakage of connected components on
the suction side and pressure side.
à
Observe the marking of inlet and outlet on
the pump head.
1. Remove the protective plugs from the hose connection threads.
2. Connect the suction line and the pressure line (for mounting dimen-
sions, see Chapter 3 Technical data ).
3. Lay the suction line and pressure line with a descent so that no con-
densate can run into the pump.
Pneumatic noises can be reduced or dissipated by using a silencer
(see Chapter
10.2 Accessories ).

WARNING
Risk of dangerous gas mixtures during pump op-
eration if the working diaphragm breaks
Depending on the medium being transferred,
breakage of the working diaphragm can result in a
dangerous mixture if the medium mixes with the
air in the innerspace between the working di-
aphragm and the safety diaphragm.
à
KNF recommends monitoring the innerspace
between the working diaphragm and the
safety diaphragm (see Fig. 4) through the
hole(s) (see Fig. 15) in the intermediate ring
for a change in pressure or the presence of
gas. If the pressure changes in the in-
nerspace, the pump is to be stopped immedi-
ately.
à
Immediately stop the pump if the working di-
aphragm breaks. Replace the working di-
aphragm and safety diaphragm prior to further
operation (see Chapter
8 Servicing ).
