Safety information about gases

The measuring instrument requires various gases for operation and measurement with
different hazard potentials. Supply all gases to the device and remove all waste gases
from it through pipelines which comply with the listed switching, connection and
pipework plans in the relevant chapters.
When working on the gas pipelines, always ensure there is adequate
ventilation and protect yourself from gases which contain aggressive or
CAUTION toxic components.
When mixed with air, gases may form an explosive mixture or be toxic,
harmful or polluting.
CAUTION
Do not supply the device with any gas which contains more than 3.0%
v/v of oxygen. Il n'est pas autorisé de connecter un gaz contenant plus de
3 % d'oxygène (basé sur le volume).
It is not allowed to connect gasses that are flammable or explosive under
CAUTION exclusion of oxygen (i.e. acetylene (C2H2)). Il n'est pas autorisé de
connecter des gaz inflammables ou explosifs à l'exception de l'oxygène
(par exemple, l'acétylène (C2H2)).
Only natural gas and gases similar to natural gas (all components in gaseous
form) as specified in the technical specifications or approved calibration gases
may be used in the specified pressure range.
ATTENTION
For other gases and pressures, please contact your TAC before use.
The equipment should not be installed in a location where it might be
subjected to external conditions which might cause electrostatic charges
on non-conducting surfaces.
CAUTION
The breather valve is not part of the waste gas system and is in direct contact with the
ambient atmosphere. Gas will only escape from the breather valve in the event of a
fault. Take suitable precautions to discharge it. For example, for installations in a
building, this may take the form of a vent line into a safe ventilation area or appropriate
ventilation of the installation site.
The breather valve must not be sealed or blocked.
It may only be replaced by personnel authorized by Honeywell.
