1.1 Rosemount 370XA Hydrogen Conversion Kit Gas Chromatograph safety warnings
Observe these safety messages for the Rosemount 370XA Hydrogen Conversion Kit Gas
Chromatograph.
WARNING
EXPLOSION HAZARD
Failure to de-energize the analyzer may cause serious injury or death to personnel.
Do not open when energized or when an explosive atmosphere may be present.
Keep cover tight while circuits are live.
WARNING
EXPLOSION/FIRE HAZARD
Failure to observe this warning may cause serious injury or death to personnel.
Do not open when an explosive atmosphere may be present.
Do not open while energized.
Use supply cables or wires suitable for at least 176 °F (80 °C).
WARNING
BURN HAZARD
Internal components may be hot. Failure to allow the GC to cool down may result in injury
to personnel.
Allow the GC to cool down before disassembling any components.
Always wear proper personal protective equipment (PPE) when disassembling the
analyzer.
WARNING
Physical access
Unauthorized personnel may potentially cause significant damage to and/or
misconfiguration of end users’ equipment. This could be intentional or unintentional and
needs to be protected against.
Physical security is an important part of any security program and fundamental to
protecting your system. Restrict physical access by unauthorized personnel to protect end
users’ assets. This is true for all systems used within the facility.

2.1 Installing the Rosemount 370XA helium to hydrogen gas conversion kit
These are the instructions to install the hardware for the helium to hydrogen gas
conversion kit for the Rosemount 370XA Hydrogen Conversion Kit Gas Chromatograph.
The installation kit (7A00003) contains the hardware necessary to convert helium to
hydrogen gas for the GC.
WARNING
Explosion Hazard
Before converting carrier gas to hydrogen, review local hazardous area requirements to
ensure compliance.
The procedure to convert the Rosemount 370XA Gas Chromatograph from helium to
hydrogen gas includes:
• Changing the thermistors (2-6-5000-084)
• Adding a carrier shut-off valve (2-4-4000-197)
• Purging the carrier gas
• Adjusting the carrier pressure (MON2000 2-3-9000-522)

2.2 Installing the carrier shut-off valve
This procedure describes installing the carrier shut-off valve and tubing for hydrogen
applications.
Refer to the Parts List and the following steps to perform this task.
WARNING
Explosion Hazard
Do not use hydrogen for valve actuation.
Procedure
1. Shut off the carrier and actuation gas supply.
2. Wait until the carrier gas pressure gauge reads zero psi.
3. Disconnect the carrier gas tubing from the tee fitting that is connected to the
carrier gas supply.
