14 DF-760E Cautions
CAUTION: OXYGEN SENSOR USE WITH PURE OXYGEN
ATTENTION : UTILISATION DU CAPTEUR D'OXYGÈNE AVEC
DE L’OXYGÈNE PUR
The DF-760 should not be used with pure oxygen. The oxygen sensor can
be permanently damaged by operation with a pure oxygen sample gas.
Le DF-760 ne doit pas être utilisé avec de l'oxygène pur. Le capteur
d'oxygène peut être endommagé de façon permanente s'il est utilisé avec
un échantillon gazeux d'oxygène pur.
CAUTION: INERT, TOXIC AND COMBUSTIBLE GASES
ATTENTION : GAZ INERTES, TOXIQUES ET COMBUSTIBLES
The DF-760, DF-750 and DF-745 analyzers have been designed for use with
inert, non-toxic, non-combustible sample gases only, such as nitrogen, helium
or argon. The DF-760, DF-750 or DF-745 may be used with the combustible
gas hydrogen if the analyzer has been factory ordered with the Hydrogen
Service Safety System option. The DF-750 and DF-745 may be used with the
reactive gas pure oxygen. The DF-740 is intended for use with the toxic gas
ammonia. The DF-730 is intended for use with the toxic gas HCl. The DF-
745SG approved gas list is ever expanding, but it includes: N2, O2, H2, He, Ar,
CO2, CO, SF6, Ne, Kr, Xe and N2O. Check your order paperwork to
determine whether your analyzer is intended for use with a toxic or
combustible gas. For toxic and combustible gases, observe the following
special installation and operation precautions:
1) Be sure to know the sample gas composition and the safe handling
requirements for that gas composition.
2) Install a shutoff valve on the sample gas inlet so that gas can be turned
off in an emergency.
3) Check all external plumbing connections for tightness before
pressurizing the sample system.
4) Vent the analyzer outlet into the appropriate facility vent system --
away from personnel (for toxic gases) and away from sources of
ignition (for combustible gases).
5) Turn off the sample gas before disconnecting the analyzer.
6) For many toxic gases a breathing air safety monitor can be purchased
(from a safety products distributor) that will notify the user if an unsafe
amount of the toxic gas is detected.
Servomex cannot be responsible for direct or consequential damages that result
from using the analyzer with these gases.
