Fire hazard. This product is not designed for use with flammable
liquids.
Make sure to use the specified tubing size.
Plumb the sample and drain lines
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 damage to the analyzer will occur
due to backpressure. Make sure that the drain lines are open to air.
N O T I C E
Do not connect a hose to the case drain unless necessary because the case
drain hose can supply a path for corrosive fumes to enter the analyzer from the
facility drain.
Plumb the drain hoses and the sample lines to the analyzer. Refer to
Figure 16 and Figure 17 . The drain hoses are supplied by the user. The
sample tubing is supplied with the analyzer.
Make sure that all the drains are at least 305 mm (12 in.) below the drain
block of the analyzer and drain to a facility chemical drain. Remove the
knock-out plugs in the bottom of each bottle enclosure to connect the
drain hoses.
If a case drain hose is necessary, make sure that there is an air break
between the case drain hose and the facility drain and that the facility
drain has a fume trap.
