Important:
If the diaphragm is not screwed
into the adapter far enough, the
closing force is transmitted directly
onto the diaphragm pin and not
via the compressor. This will cause
damage and early failure of the
diaphragm and thus leakage of the
valve. If the diaphragm is screwed
in too far, perfect sealing at the
valve seat will not be achieved. The
function of the valve is no longer
ensured.
Important:
Incorrectly mounted diaphragm
may cause valve leakage /
emission of medium. In this case
remove the diaphragm, check the
complete valve and diaphragm and
reassemble again proceeding as
described above.

Anti-twist system of the spindle at the
compressor
A double flat (arrows picture 2) is fitted at
the end of the actuator spindle to protect
the actuator spindle against twisting. When
mounting the compressor, the double flat
must be in correct alignment with the recess
of the compressor back (arrows picture 1).
If the actuator spindle is not in the correct
position, it must be turned to the correct
position. The position of A is offset by 45° to
the position of C.
Place the compressor loosely on the
actuator spindle, fit the recesses D into the
guides C and A into B. The compressor
must be able to be moved freely between
the guides!
