The unique ones are identified in Figure 2. Capillary column spring clips Valve box blanking plate Oven bracket assembly Compact splitter with makeup gas assembly This assembly is shipped in a plastic bag to keep contaminants out of the tubing and the fittings. Do not open the bag until you are ready to install the splitter.

Figure 3 Remove the valve box cutout WARNING 18 Installation and Operation Guide Hardware Installation 2 3 This exposes a layer of soft insulation. Remove it to expose the hard oven insulation. Remove the precut insulation piece at the location shown in Figure 4. Figure 4 Remove the insulation cutout 4 Replace the soft insulation. Install the valve box blanking plate, using one screw at the front and one at the rear to secure it. See Figure 5.

Clip — (1 of 4) Oven shroud Figure 6 Oven clips 20 Installation and Operation Guide Hardware Installation 2 Install the Bracket and Splitter The splitter is usually installed on the right side of the oven. note The body of the splitter may be discolored as a result of the deactivation process. This is not a defect. 1 Place the bracket against the side of the oven. The two notches should be up and the standoffs should face the center of the oven. 2 Use two T-shaped thumbscrews to fasten the bracket to the T-slots in the oven wall (Figure 7). Figure 7 Installing the bracket Installation and Operation Guide 21 2 Hardware Installation CAUTION Use extreme care to prevent any fragments of insulation or other material from entering the makeup gas tubing or the fittings on the splitter assembly. Such materials could block the internal passages in the splitter or the bore of the capillary restrictors. CAUTION In the following steps, bend the tubing over an object such as your thumb to avoid kinks. 3 Open the plastic bag and remove the splitter assembly. Install a plastic cap on the end of the makeup gas tubing. Place small pieces of tape over the open end of the fittings. 4 Prebend the tubing according to Figure 8. This will make splitter installation much easier. 5 Push the end of the makeup gas tubing up through the top oven wall so that the end of the tubing comes out in the hole of the valve box blanking plate. 22 Installation and Operation Guide Hardware Installation 2 6 Route the prebent tubing against the oven wall and top to keep it clean for future maintenance. It should be behind the back detector location. 7 Screw the splitter assembly to the bracket (three screws).

To supply the makeup gas froma PCM 1 Connect the tubing from the PCM to the 1 meter length of stainless steel tubing from the kit with a union. 2 Connect the free end of the stainless steel tubing to the tubing from the splitter assembly with a union. See Figure 10. Stainless steel tubing PCM -□——□-► To splitter Union Union Figure 10 Plumbing a PCM makeup supply To supply the makeup gas from an Auxiliary Pressure controller 1 Install the brown-dot frit (part no. 19231-60610) in the output channel. See your GC manual for details. 2 Connect the tubing from the Auxiliary Pressure controller to the tubing from the splitter assembly with the 1/8 to 1/16-inch stainless steel reducing union. This completes the hardware installation. 24 Installation and Operation Guide Agilent G3180B Splitter Kit Installation and Operation Guide • • # # • • • 3 Splitter Configurations Typical Configurations 26 Splitting to an MSD 28 Custom Configurations 29 Restrictor id and length 32 Maximum and minimum flows 33 Column outlet pressure 34 Inlet pressure 34 Restrictor and Column Installation 35 Ins...
