Figure 15 Mounting the rinsing and aspiration tubings
1 Mount the rinsing tubings
￭ Manually tighten the three 6.1805.060 FEP tubings (60 cm) in
the M6 bore holes of the distributor. Place the tubings into the guide
chain (see Chapter 3.9, page 24).
These are the feed lines for the spray nozzles.
2 Mount the aspiration tubing
￭ Manually tighten the 6.1805.510 FEP aspiration tubing (60 cm)
in the M8 bore hole of the distributor.
3 Mount the feed line for the rinsing liquid
￭ Remove the union nut of the left-hand connector of the distributor
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 tubing 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.
