Chapter 4: Installation
3. The waste tube fitting requires a vent tube to be attached to ensure that corrosive and noxious gases
are routed away from the instrument. The vent tube should be connected to the upper straight barb
fitting and routed at least 2 meters away.

If the Online unit is installed in a closed cabinet or small enclosed room, it is required to vent the
waste line as described in step 3.

The waste container can be located on or below the surface on which the Analyzer is at or below the
bottom of the Analyzer. Do not place the waste container higher than that surface because the gas-
liquid separator will not drain properly. Also, try to minimize the length of tubing used and ensure a
straight tubing path (avoid bending the tubing).
Warning
To protect against inhalation of toxic fumes, make sure the Analyzer is installed in a
well-ventilated area. Depending on the composition of the sample, halogens such
as chlorine or bromine, or toxic fumes from fluoride, cyanide, or other toxic salts,
can be emitted into the Analyzer’s waste. To protect against inhalation of
hazardous fumes, add sodium hydroxide (lye) or sodium carbonate (soda ash) to the
waste container to neutralize acid in the waste. Avoid stratification of the waste
within the container by occasionally agitating the container.
