• Prepare aspirating tubing 89: Cut a piece of the 6.1803.020
PTFE tubing to the required length (normally ca. 120 cm).
• Pull one end of aspirating tubing 89 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 102 attached to the rinsing so-
lution storage bottle and tighten it so that the tubing is firmly
held.
• Insert the free end of aspirating tubing 89 into one of the
openings in 12 of the 761 Compact IC (see Fig. 2) from
above and pull it sufficiently far into the interior.
• Mount a coupling 91 (6.2744.030) to the inlet end of the front
pump tubing 93.
• Mount a 6.2744.010 Compression fitting at the end of the
aspirating tubing 89 and screw this compression fitting on to
the coupling 91 (see Fig. 16).
