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.

The pressure regulator is set to a fixed pressure and cannot be changed.
Use the supplied tubing (6 mm), Y-strainer with filter and pressure
regulator to plumb the drain and the sample to the analyzer. Refer to
Figure 6 . The sample line tubing that goes into the plumbing access
ports must be 6 mm. Tubing of 1/4 in. may be used for the sample line
up to the valve/y-strainer but not into the plumbing access ports of the
analyzer.
