3 Mount the feed line for the rinsing liquid
￭ Remove the union nut of the left-hand connector of the distribu-
tor and guide it over the end of a 6.1812.000 PTFE tubing.
You may have to extend the tubing end in order to be able to
better mount the tubing, see note below. Pull the end of the tub-
ing over the connection nipple of the distributor and fasten in
place with the union nut.
The tubing leads to the rinsing pump (Pump 1) and can be cut to
the correct length.
Note
The opening of the tubing may need to be widened with a sharp
object (e.g. with a Phillips screwdriver).
A piece of sandpaper may be used to get a better grip on the tub-
ing.
Do not extend the tubing end before having slid the union nut
onto the tubing.

Pull the end of the tubing over the connection nipple of the distri-
butor and fasten in place with the union nut.
The tubing leads to the aspiration pump (Pump 2) and can be cut
to the correct length.
