Shine a flashlight through the cell.
For G.P. Systems, open control/analysis unit and check optical train for proper beam alignment from source end to detector input.
Remove the cell assembly. Inspect the cell as described in E.P. Systems. Disassemble the cell in a dry room where needed and clean the cell with hot water and detergent.
7.7Sample System Maintenance
The sample system can be quickly cleaned. All components are connected to the equipment panel by Swaglok type fitting. Remove all components and clean with hot water and detergent. It is recommended to renew, rather than clean the piping which makes up the sample flowpath.
7.8Zero Filter Replacement
The system is equipped with a polypropylene element when the range is 10 ppm or less. A new filter releases small amounts of signal producing chemicals, which produce an unacceptable zero reading for this narrow range. The poly propylene filter(s) element must be cleaned and rinsed of contaminats before use. Wash thoroughly in dtergent, hot eater, then rinse capiously with very clean dimeneralized or tap water severa times before
Clean througly or replace the filter element:
1.Stop the sample flow.
2.Open the zero system vent valve. This will vent most of the zero system water.
3.With an adjustable wrench, open the filter housing.
4.Replace the polypropylene filter element. Clean the element when it not appear very dirty and reinstall or replace with a spare unit. For cleaning procedure see Section 7.8.
5.After installation, with the proper care that the gaskets are in place and the filter housing properly tightened, start the sample flow. Flush the new filter element by filling and draining the filter housing with sample several times, by means of the safety vent valves, V4 and V3.
