2.8.3 Connection of supply bottles
The supply lines for the regeneration and rinsing solution between the
storage bottles and the peristaltic pump are installed as follows (see
Figure 17):

).
• Fill regeneration solution into supply bottle 89 (amber glass,
1 L) and label the bottle.
• Screw bottle attachment 88 on to supply bottle 89.
• Place supply bottle 89 at one of the rear positions of the bot-
tle rack 6 on the 861 Advanced Compact IC (see Figure 1).

• Prepare aspirating tubing 76: Cut a piece of the 6.1803.020
PTFE tubing to the required length (normally approx. 120
cm).
• Pull one end of aspirating tubing 76 through a PEEK com-
pression fitting 54 (6.2744.010) so that approx. 30 cm of the
tubing projects.
• Screw PEEK compression fitting 54 with tubing into one
opening of bottle attachment 88 attached to the regeneration
solution storage bottle and tighten it so that the tubing is
firmly held.
• Insert the free end of aspirating tubing 76 into one of the
openings in 8 of the 861 Advanced Compact IC (see Figure
