WARNING .
POSSIBLE EXPLOSION HAZARD
This analyzer is of a type capable of analysis of sample gases which may be flammable. If used for
analysis of such gases, the instrument must be either in an explosion-proof enclosure suitable for
the gas, or, protected by a continuous dilution purge system in accordance with Standard
ANSI/NFPA-496-1086 (Chapter 8) or IEC Publication 79-2-1983 (Section Three).
If gases are introduced into this analyzer, the sample containment system must be carefully leak-
checked upon installation and before initial start-up, during routine maintenance and any time the
integrity of the sample containment system is broken, to ensure the system is in leak-proof
condition. Leak-check instructions are provided in Section 2-7, page 2-10.
Internal leakage of sample resulting from failure to observe these precautions could result in an
explosion causing death, personal injury, or property damage.
