3.7 Installing rinsing and aspiration equipment
Various tubings are necessary for rinsing the electrode and the dosing tips
as well as for aspirating the sample solution after the titration. First,
mount the tubings on the distributor.
Mounting the rinsing and aspiration tubings
Install the tubings as follows:
6.1805.510
6.1805.060
6.1808.170

Figure 16 Mounting 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 3.3, page 17).
These are the feed lines for the rinsing 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. Pull
the end of the tubing over the connection nipple of the distribu-
tor and fasten in place with the union nut.
The tubing leads to the rinsing pump (pump 1 of the 843 Pump
Station) and can be cut to the correct length.
