Chemical exposure hazard. Dispose of chemicals and wastes in accordance with local, regional and
national regulations.
N O T I C E
Do not connect the drain lines to other lines because backpressure or damage to the analyzer can occur. Make
sure that the drain lines are open to air.
N O T I C E
To prevent backpressure and damage to the analyzer, make sure that the analyzer is higher than the facility
drain(s) used and that the drain line has a constant downward slope.
Use the supplied tubing (6 mm), shut-off valve, Y-strainer with filter and pressure regulator to plumb
the drain and the sample to the analyzer. Refer to
Figure 5 and Figure 6 . The sample line tubing that
goes into the plumbing access ports must be 6 mm. Tubing of 1/4 in. can be used for the sample line
up to the valve or to the y-strainer, but not into the plumbing access ports of the analyzer. For correct
drainage, install the drain lines at least with a 1-inch decrease in height per 1 foot of tubing length.
