ACF5000 FTIR ANALYZER SYSTEM | OI/ACF5000-EN REV. A 11
Safety instructions for handling the analyzer system with
integrated FID
Safety measures
If an FID (VOC analyzer) is installed in the analyzer system, the following
safety measures are taken at the factory to ensure safe operation:
Installation of a hydrogen flow restrictor in the cabinet wall (bulkhead
fitting with an integrated flow restrictor, max. 10 l/h, for connection to
the combustion gas line),
Use of stainless steel piping, compression fittings and valves,
Shutoff of the hydrogen supply in the event of malfunctions,
Check of the combustion gas paths for leaks inside the analyzer cabinet,
Installation of pressure equalization fittings on the top of the cabinet to
allow escape of hydrogen to the outside in the event of leaks.
As an additional safety measure, the analyzer system can be equipped with
the option “Hydrogen monitoring of the analyzer cabinet” (see page 18)
The combustion gas path in the analyzer cabinet and especially in the inte-
gral FID must not be opened! The combustion gas feed path can become
leaky as a result!
If the combustion gas path inside the analyzer cabinet nevertheless is
opened, it is essential that it be subjected to a leak test with a hydrogen leak
detector after it is closed again!
The bulkhead fitting with integral flow restrictor for connection of the com-
bustion gas line is a safety-relevant component. It may be replaced only by
certified service personnel.
The integrity of the combustion gas path in the analyzer system as well as
the combustion gas feed line must be checked prior to commissioning as
well as regularly during operation.
Combustion gas that escapes from leaks in the gas paths can cause fires and
explosions, even outside the analyzer system!
Sufficient ventilation must be provided at the installation site of the analyzer
system.
