Attach pump tubings
• Loosen both tubing cartridges 44 from the holding clamp 99 by
pressing down snap-action lever 1010 and remove from
mounting pin 1212 on the 753 Suppressor Module (see Fig. 1).
• Press contact pressure lever 55 on both tubing cartridges
down as far as it will go.
• Insert a length of pump tubing 3333 (6.1826.050) into each of
the tubing cartridges as shown in Fig. 7. The white-yellow
stopper 3434 must click into the corresponding holder on the
left-hand side of the tubing cartridge.
• Place the tubing cartridges on mounting pin 1212 and press
down on the right-hand side until snap-action lever 1010 clicks
into position on holding clamp 99. Take care that no kinks are
formed in the pump tubing.
