3Ć39 Maintaining the System
Yearly Maintenance
Perform the following procedures every 12 months. These procedures are based on
analyzing 30 samples per day. If your laboratory analyzes more than 30 samples
per day, perform this maintenance more frequently.
Use this procedure to replace the tubing on the sample pump, the waste pump, the
reagent pump, and the CO-ox module pump. The sample pump, waste pump, and
CO-ox module pump tubing assemblies each contain one piece of tubing. The
reagent pump tubing assembly contains two pieces of tubing.
Replacing the Pump Tubing
NOTE: When you replace pump tubing, replace the tubing for all the pumps.
Replacing the tubing on only one or two pumps can affect pump calibration and
cause incorrect flow rates.
Materials required:
S sample pump tubing assembly
S waste pump tubing assembly
S reagent pump tubing assembly
S CO-ox pump tubing assembly
