2.8.2 Preparation of the peristaltic pump
Before start-up the accessories for the 2-channel peristaltic pump built
into the 861 Advanced Compact IC must be mounted according to
Figure 15. Proceed as follows:
1 Remove tubing cartridges
• Loosen both tubing cartridges 47 from the holding clamp 49
by pressing down snap-action lever 50 and remove from
mounting pin 52 (see Figure 16).
2 Insert pump tubings
• Press contact pressure lever 48 on both tubing cartridges
down as far as it will go.
• Insert the pump tubings 78 and 79 (6.1826.110) into each of
the tubing cartridges as shown in Figure 15. The orange-
yellow stopper 80 must click into the corresponding holder on
the left-hand side of the tubing cartridge.
3 Attach coupling to pump tubing
• Attach PEEK coupling 77 to the aspiration end of pump tub-
ings 78 / 79 (see Figure 15).
• Mount PEEK coupling 81 with filter and tubing security device
(6.2744.180) to the delivery end of pump tubing 78 / 79.
This is done by dismantling the tubing security device and
first pushing the sleeve nut and the compression piece onto
the tubing.
Attach the tubing to the PEEK coupling and screw the sleeve
nut onto the coupling in order to secure the tubing.
4 Attach tubing cassettes
• Hinge the tubing cassettes on holding pin 52 and press
down on the right-hand side until spring lever 50 clicks into
position in holding clip 49. Take care that the pump tubing
does not kink.
5 Connect suppressor inlet capillary
• Attach "Suppressor inlet capillary for H
