from the water bottle and set it aside, with the connector pointing upward if possible. Use
the paper towels to dry any water that leaks out of the water connector tubing.
28. Remove the resin bed by pressing down on the metal set plate and then pulling the resin
bed downward and away from the DI water reservoir. Hold the resin bed over a flask,
remove the red plug, and drain water from the resin bed. You may need to gently shake the
resin bed to help the draining process.
29. Return the resin bed to the Analyzer. Depress the metal set plate and insert the post at the
top of the resin bed up into the DI water reservoir. When the resin bed is securely in place,
release the set plate.
30. Reattach the DI water connector tubing to the bottom of the resin bed, making sure that
the tab extends through the slot on the set plate by rotating the tubing.
31. Empty the water in the water bottle and replace the water bottle cap.
32. Locate the green restrictor tubing that connects to each solenoid valve (see Figure 46).
33. Disconnect the restrictor tubing and pump tubing from each solenoid valve. To remove
water from the measurement module, follow this step for both pieces of tubing: squeeze
the water bottle; attach the nozzle of the water bottle to the tubing, gently release the
pressure on the water bottle to suck the water into the water bottle; disconnect the water
bottle from the pump tubing (see Figure 47).
34. Reattach each piece of green restrictor tubing and norprene tubing to the solenoid valves.
35. Close the Analyzer case.
The second task is to drain the sample side of the fluidics.
36. Turn the Analyzer on with the main power switch.
37. Disconnect the Sample Inlet from the Analyzer, so that there is no sample source.
38. Press the Start Analysis button. Let the Analyzer run until sample stops flowing out of the
waste tubing. As soon as sample stops flowing, press the Stop Analysis button.
39. Turn the Analyzer off with the main power switch.
40. Disconnect the waste tubing from the Analyzer.
41. Remove any printer, alarm, analog output, or computer cables and the power cord
connected to the Analyzer. Note that you may need an electrician to help you disconnect
the Analyzer from the power supply.
You can now repackage the Analyzer and ship it to GE Analytical Instruments.
For international shipments, coordinate with a GE Analytical Instruments representative to ensure
quick passage through customs.
