In the event of spills or leaks from the sample and enclosure drains, some waste may be released. Waste
contains sample and chemical reagents in low concentration. Refer to the reagent MSDS and local regulatory
agencies for correct waste disposal.
Note: Make sure that the enclosure drain is open. The drain must be open to remove sample water if leaks occur.
3.4.1 Install the sample line
Use the contents of the installation kit to install the sample line. Select a sample point that represents
the condition of the entire system. To avoid irregular results, do not install the sample line close to
points of chemical additions. Figure 6 shows examples of sample line installations.
Note: Sample pressure greater than 10 psig at the instrument inlet can cause the reagents and sample to overflow.
To connect the sample line, refer to Figure 7. Make sure that the tubes are pushed all the way on the
connector. Hold the sample tube inside the analyzer and push the shutoff valve onto the tube. Do not
bend the sample tube. Incorrect installation can cause the tube to come off of the connector when
water pressure is applied.
