2. With the analyzer inlet and outlet water connections open to atmosphere, apply
power to the analyzer.
3. In the TOC setup dialog box under the general tab, select “use pump”.
4. At the home screen, touch the << icon to open the sliding toolbar.
5. Touch the diagnostics icon.
6. Touch the tests tab, then touch the plumbing test icon.
7. Follow the procedure described in Plumbing test, page 131, to drain the water from
the analyzer (flow through cell with pump and sample from all four bottles locations).
8. If necessary, repeat Step 4 through Step 7 until all water has drained from the
analyzer.
