Figure 8 Mounting the rinsing and aspiration tubings
1 Mount the rinsing tubings
￭ Manually tighten the three 6.1805.420 FEP tubings (48 cm) in
the M6 bore holes of the distributor. Place the tubings into the
guide chain (see Chapter 3.5, page 19).
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 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.
