To Remove the Syringe on the 7693A ALS
To remove a syringe:
1 Unplug the injector cable, and if desired, mount the
injector on a parking post.
2 Open the injector door.
3 Slide the syringe carriage to the top position.
4 Completely loosen the plunger thumb screw until it
reaches the stop, and lift the plunger carrier off of the
syringe plunger.
5 Open the syringe latch by swinging it in a
counterclockwise direction.
6 Carefully pull the top of the syringe out of the flange
guide, then lift the needle out of the needle support foot.
To install a syringe, see “To Install a Syringe on the 7693A
ALS” for details.
Be careful not to bend the syringe needle. Only pull the syringe out
of the carriage until clear. The needle bends easily when still seated
in the needle support guide.
