Note: The changing of the V-rings/O-rings on the
individual nose cones is described in detail in
the instructions enclosed with the spare part.
The main components of the manifold
A
Piston unit with piston support bar [ I ] and pistons
inserted in this unit, which can be screwed out indivi-

Nose cone assembly with nose cone support bar [ II ]
and central guide rod (Z), which is attached to this,
and the nose cones and seals, which can be screwed
out individually for cleaning or replacement.

sample, and then hold the instrument in a vertical position
for about 10 sec. If a drop forms at the tip orifices, see
the troubleshooting guide on page 64.
