Page 17: Calibration
Calibration The Analyzer has been shipped with a factory calibration. Typically this calibration is accurate enough for most applications. Lab standards can be used to verify the analyzer’s accuracy. When using a laboratory standard, allow at least 500 mL of sample to flush through the cell before the analysis. -
Page 18: Maintenance
Maintenance The analyzer has been designed to minimize the total amount of maintenance time. Typically the analyzer requires less than 2 hours of maintenance per month. Maintenance Schedule Routine maintenance of the analyzer is limited to a few periodic procedures as follows: Daily - Observe analyzer and confirm normal operation Quarterly*... -
Page 19: Maintenance Procedures
Maintenance Procedures The following pages are procedures describing the routine maintenance operations. Interrupting On-Line Operation To interrupt on-line operation the “Main Menu” key is pressed. If the security code has been set to a value other than 0, the security code must be entered. Sample Line Screens The sample line inlet is equipped with a small mesh screen to prevent the entry of large particles and debris into the system. - Page 20 Peristaltic Pump Maintenance To ensure reliable operation of this analyzer the peristaltic Air Pump requires the following maintenance procedures: 1.) The Air Pump Head Assembly requires replacement on a periodic basis – every second reagent change – typically every six months. A replacement pump head is provided in the “Startup Kit”...

Page 23: Flow Cell - Physical Cleaning
Flow Cell - Physical Cleaning n most applications, the acid based reagent and cleaning solution will keep the flow cell windows clean. However, in some waste-water or industrial installations or under severe operation conditions, a film may build up on the windows that the cleaning solution does not remove. (as evidenced by, for instance, less than 1 volt detector signal when doing a manual zero). -
