14
• Pull outlet capillary 27 27 marked with "Waste" at suppressor
connection 22 22 (see Fig. 6) through one of the rear panel
openings 29 29 of the 690 Ion Chromatograph.
• Lead outlet capillary 27 27 to a sufficiently large waste container
and fix in place.
10 Startup of 753 Suppressor Module
• Set switch 22 on 753 Suppressor Module to
"OFF".
• Switch on 753 Suppressor Module with mains switch 13 13 and
set switch 33 to "ON".
• Adjust the contact pressure for both tubing cartridges: press
contact pressure lever 55 upwards until the solutions just start
to be drawn in. Then press the contact pressure lever up-
wards until it clicks once more to obtain optimal contact pres-
sure.
• Before switching the suppressor to the next position for the
first time rinse all three suppressor units with solution for
5 min.
• Check all tubing from the storage vessels through the tubing
cartridges and the suppressor up to the waste containers for
leakage of liquids. If liquid escapes anywhere the corre-
sponding compression fitting must be tightened further or
changed.
Pump tubings are consumable material with a lifetime which depends
on the contact pressure. This is why the tubing cartridges should be
raised completely by loosening snap-action lever 10 10 on the right-hand
side if the pump is to remain switched off for a considerable length of
time (the set contact pressure remains unchanged).
