C A U T I O N
Explosion hazard. Use only the supplied regulator from the
manufacturer.
C A U T I O N
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 or backpressure and 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.
N O T I C E
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.
