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 tubing.
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 distributor
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 distributor
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.
