8. Gently squeeze the water bottle to flush water into the restrictor tubing. Note that water
will come out the Analyzer’s sample inlet line or the IOS System; when the water flows out,
the obstruction has been cleared.
9. Remove the water bottle and connector tubing from the restrictor tubing, and reconnect
the sample pump tubing to the restrictor tubing.
10. Disconnect the two pieces of sample pump tubing from the Y-fitting and confirm that both
sides are now flowing at the same rate. If they are not, you may need to repeat Steps 6 and
7. If the problem persists, contact Technical Support.
11. The second task is to test the DI fluidics side for an obstruction. If you placed the Analyzer
into analysis while testing the sample side, press the Stop Analysis button now; if you
used the Diagnostics menu to turn on the sample pump, turn it off now.
12. Disconnect the tan tubing and connector tubing that connects to the DI water reservoir
(see Figure 43). As for the sample pump tubing, check the rate at which water flows
through the two pieces of tubing.
If the water drops at the same rate, there is no DI-side obstruction and you can replace the
tubing on the DI water reservoir.
If the water drops more slowly through one of the pieces of tubing than the other, proceed
to the next step.
