Startup of 753 Suppressor Module
Set switch <REMOTE> 22 on 753 Suppressor Module to
"OFF".
Switch on 753 Suppressor Module with mains switch 1313 and
set switch <PUMP> 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 1010 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).
