NSTALLATION
WARNING: POSSIBLE EXPLOSION HAZARD
In the event that flammable sample is to be introduced into this analyzer, it must
be equipped with accessory kit PN 624080, which restricts sample flow and
provides automatic sample shutoff in the event of burner flameout. DO NOT
OPERATE WITHOUT SAMPLE FLOW RESTRICTOR IN PLACE.
containment system should also be thoroughly leak checked.
designed considering application on hydrogen sample (LEL=4% v/v).
instrument must not be used on a sample having a LEL less than 4% in air.
2.6 GAS CONNECTION
For external gas lines, the use of all new tubing throughout is strongly recommended.
Copper refrigeration tubing is preferred. Stainless steel tubing is less desirable,
because it contains hydrocarbon contaminants, necessitating thorough cleaning
before installation.
In connecting gas supply lines and associated fittings, use Teflon tape only. Do not
use pipe thread compound or other substance with an organic base.
WARNING: POSSIBLE EXPLOSION HAZARD
Do not apply power to analyzer or ignite burner until all leak checks have been
performed and until the environment of the analyzer has been determined to be
non-hazardous. See Section 2.7 for leak check procedure.
This analyzer has been designed for use in environments that do not contain
combustible or explosive materials.
This analyzer uses a fuel containing hydrogen. Leakage from the fuel containment
system can result in an explosion. The fuel supply and containment system, both
inside and outside the analyzer, should be carefully checked for leaks upon
installation, before initial startup, during routine maintenance or any time the integrity
of the sample containment system is broken.
If hazardous sample is to be introduced into this analyzer, the leak check
procedure should also be applied to the sample containment system, both
inside and outside the analyzer.
Proceed as follows:
1. Check analyzer to make sure that plugs and caps are removed from all inlet and
outlet fittings.
