Step 3: Review Solutions for Basic Problems
If a visual inspection of the Analyzer does not help you identify the source of the problem you are
experiencing, consult the specific problems discussed in this section.
The Analyzer Will Not Power On
The Analyzer’s main power switch is a circuit breaker. If conditions cause the breaker to be
switched to the Off position during normal operation, simply press the switch into the On position to
resume operation; if the Analyzer was taking measurements when the power interruption occurred,
it will automatically resume analysis when power is restored. If you are unable to switch the breaker
to the On position (e.g., it repeatedly switches back to the Off position), you should contact
Technical Support for assistance.
Problems with the DI Water Pump
If the Analyzer is making a loud squealing sound or if water is not filling the tubing that leads to the
resin bed, it is likely that the DI water pump has not been properly primed. To prime the pump, you
will need the water bottle from the Analyzer’s accessories kit and a bottle or tray to collect water.
1. Make sure the Analyzer is powered on.
2. Remove the Lower tube (Item 1 in Figure 39) from the bottom of the resin bed. Place the
tube into a bottle or tray, as water will drain from this tube.
3. Remove the inlet cover on the DI water reservoir (Item 3 in Figure 39). Water will drain from
the tube when you remove the inlet cover.
4. When water starts flowing through the tube, replace the inlet cover.
5. Connect the tube back to the resin bed.
6. If necessary, add water to the DI water reservoir with the water bottle.
7. Wait 1 to 5 minutes and then turn off the Analyzer.
8. Wait 1 minute, and then power the Analyzer on. If you observe small bubbles in the tubing
that leads to the resin bed, tap the tubes to dislodge the bubbles.
9. Allow the DI water pump to circulate water for at least 10 minutes.
