1.1 Rosemount™ Gas Chromatograph safety warnings
Observe these safety messages for the Rosemount 370XA Gas Chromatograph.
WARNING
EXPLOSION HAZARD
Do not open when energized or when an explosive atmosphere may be present.
Failure to de-energize the analyzer may cause serious injury or death to personel.
WARNING
EXPLOSION HAZARD
Keep cover tight while circuits alive.
Failure to de-energize the analyzer before removing the cover may cause serious injury or
death to personel.
WARNING
EXPLOSION/FIRE HAZARD
Do not open when an explosive atmosphere may be present.
Do not open while energized.
Use supply cables or wires suitable for at least 80 ℃ (176 ℉).
Failure to observe this warning may cause serious injury or death to personnel.
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

2 Installation
2.1 Installing the gas separation kit
These are the installation instructions for the actuation and carrier gas hardware
separation kit for the Rosemount™ 370XA Gas Chromatograph.
This installation kit contains the hardware necessary to separate the actuation gas supply
from the carrier gas supply for the analyzer.
The contents of the kit are listed in Table 3-1 and are illustrated in Figure 3-1.
Procedure
1. Shut off the carrier and actuation gas supply.
2. Disconnect the actuation gas tubing from the tee fitting and analyzer manifold as
shown in Figure 3-2. Note that the tee fitting may be positioned differently in the
original installation.
3. Screw the cap plug (Figure 3-2, Item A) onto the tee fitting where the actuation gas
tubing was attached. If the analyzer is in a factory supplied enclosure proceed with
Step 4, Step 5 and Step 6. Otherwise skip to Step 7.
4. If the analyzer is in a factory supplied enclosure, drill another hole through the
enclosure to install a bulkhead fitting for the actuation gas supply. The gas line
bulkhead fittings are located on the lower left side of the enclosure. Drill a 29/64 in.
diameter hole approximately 1 in. to 1½ in. horizontally from the forward bulkhead
fitting as shown in Figure 3-3. Install the bulkhead fitting (Table 3-1, Item G).
5. Cut a length of ⅛ in. tubing (Item F) sufficient to extend from the actuation gas
manifold inlet to the bulkhead fitting. A tubing nut and front and rear ferrules
(Table 3-1, Items C, D and E) are required to connect the tubing to the manifold.
The bulkhead union includes the nut and ferrules.
6. Trim the remaining unused tubing to connect the other end of the bulkhead fitting
to the actuation gas supply. A ⅛ in. tube fitting with male ⅛ NPT threads (Figure
3-2, Item B) is commonly used to connect ⅛ in. tubing to the actuation gas pressure
regulator.
7. Cut a length of ⅛ in. tubing (Table 3-1, Item F) sufficient to extend from the
actuation gas manifold inlet to the actuation gas supply. A tubing nut and front and
rear ferrules (Table 3-1, Items C, D and E) are required to connect the tubing to the
manifold. A ⅛ in. tube fitting with male ⅛ NPT threads (Table 3-1, Item B) is used to
connect ⅛ in. tubing to the actuation gas pressure regulator.
8. Open the carrier and actuation gas supplies and set the pressures as appropriate.
