Section 5 Startup

5.1 Start the instrument

Note: Install the pressure plate correctly to prevent sample flow directly into the reagents. Refer to
valve pressure plate on page 11.
1. Open the supply valve to the instrument.
2. Let the pressure in the tubes stabilize.
Note: If leaks occur under pressure, examine all connections. Secure connections until all leaks have stopped.
3. Set the power to on.
4. Operate the instrument for approximately 2 hours with the sample and reagents.
Note: The sample cell will have bubbles on the surface until it is fully wetted. The bubbles can cause irregular
readings until the sample flow stabilizes.

5.2 Prime the reagents (optional)

Prime the reagents to decrease the start up time to 15 minutes.
1. Set the sample flow to the instrument to off.
2. Disconnect the reagent feed line after the "Y" fitting at the colorimeter.
3. Connect a syringe to the tubing that comes from the "Y" fitting.
4. Loosen the two screws on the pump pinch plate so that the reagents can be pulled through the
reagent lines.
5. Use the syringe to remove the air and fill the lines with reagent.
