Overview Overview This section reviews the procedure for installing a nonEPC split/splitless inlet on an Agilent 6890 Gas Chromatograph (hereafter referred to as the GC). Before you begin, review the safety information found on the inside of the front cover. A G1585A must be installed prior to this installation. - Page 4 Overview Heater/sensor wire Chemical filter Split/splitless inlet Flow label plate Manual flow controller Power switch...

Page 7: Installing The Inlet
Installing the inlet Installing the inlet From the front of the instrument, locate the inlet chassis. Inlet chassis Remove the round metal cutout in the front or back inlet position, if necessary. Insert a screwdriver blade into the slot in the cutout and move it back and forth until the cutout breaks free from the sheet metal. - Page 8 Installing the inlet Carefully remove the scribed circle of insulation from the oven top to create an opening into the oven, if necessary. Method 1: Use a sharp knife to cut out the insulation using the scribed circle as a guide. Method 2: Pierce the insulation with a screwdriver.
- Page 9 Installing the inlet From the left side of the GC, locate the heater/sensor wire and its corresponding connector. Tuck the heater/sensor wire underneath the clip at the side of the GC and connect it to the nearest square connector. = Heater/sensor cable routing Back inlet connector Front inlet connector...
- Page 10 Installing the flow manifold Installing the flow manifold If you are installing an inlet in the back position, remove the flow bezel bracket. Remove the hex nut at the bottom of the bezel support bracket using a 7-mm nut driver. Set it aside. Remove the flow-control label plate from the inlet front or back position on the flow bezel.
- Page 11 Installing the flow manifold Remove the (25-mm) screw from the flow carrier. Position the flow module so that the hole in its bracket lines up with the holes in the carrier. Place the flow module on the two threaded studs on the back of the flow bezel.

Large-hole insulation Small-hole insulation Insulation cup From inside the oven, install the two heat-resistant screws in the cutouts adjacent to the inlet. Do not tighten the screws. Push the insulation cup over the front or back inlet until it is flush with the oven top and rotate it until the slots in the cup hook over the screws.
- Page 15 Restoring the GC to operating condition Restoring the GC to operating condition Reinstall the flow carrier cover and replace the two screws. Replace the fan cover. Reinstall the injection port cover or tray bracket. Plug in and turn on the GC. The GC is aware that a nonEPC inlet is present—it looks for the heater/ sensor connections—but does not know what kind.
