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.
4 Mount the outlet tubing
￭ Remove the union nut of the right-hand connector of the distribu-
tor and guide it over the end of the 6.1812.000 PTFE 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.
