cabling under the injection port cover are properly routed in their channels.
Choosing the turret type to use
Your HP G2613A Injector comes with 2 types of turrets, a standard turret for use
with or without a tray, and an alternate 8 sample position turret which is used
without a tray. If you are using the optional HP G2614A Tray, the injector comes
pre-configured with the proper turret type.
If you are not using a tray, you may use 1 to 3 sample vials in the standard turret.
If you wish to use up to 8 sample vials, you may remove the standard turret and
install the alternate 8 sample position turret. See Removing the turret for details.
Note After changing turrets, it is recommended that you perform the turret alignment

Maintenance
This section contains some suggestions for ensuring good performance of your
HP 7683. The maintenance interval varies with the use of the instrument.
Caution Do not use any lubricants on the HP 7683 Automatic Liquid Sampler. They may
effect the chemical performance of the GC and damage the instrument.
On an occasional basis:
❒Clean the surface of the tray arm, gripper, gripper jaws, and tray quadrants.
❒Clean the needle guide and nearby surfaces of the injector. Dust and dirt
accumulate in these areas and can be picked up by the syringe needle and
carried into the inlet.
❒Clean the surface of the injector. Vacuum off any dust that builds up around
the vents.
❒Make sure the injector mounting post is tight.
❒Make sure the tray mounting screws are tight.
❒Make sure the knurled nut on the top of the turret is tight.
❒Be sure all the cables are securely attached.

Removing the turret
If you need to remove or replace your turret, use the following instructions for
proper replacement.
1. Disconnect the injector cable from the GC.
2. Open the injector door. Unscrew and remove the knurled nut from the top
of the turret. See Figure 9.
3. Rotate the turret so that the open section faces the back of the tower and
the arrow on top of the turret points directly back (see Figure 9). Push the
stripper arm toward the back, then lift the turret up so that it clears the
center shaft.
4. To install the replacement turret, align the tab on the motor hub with the
slot in the underside of the turret.
5. Push the stripper arm to the back of the tower, insert the turret with the
open section facing the back of the tower and the arrow pointing back, and
install the turret with the tab seated in the slot. Seat the turret on the hub,
rotating it gently if necessary until it drops completely into position. The top
of the threaded shaft should be almost level with the top of the turret.
6. Replace the knurled nut and tighten it firmly (finger-tight).
7. Close the injector door.
8. Plug the injector cable into the GC and check for the Ready light.
