Attaching the Barrel / Purging the Tip
NOTE:
Stay in MANUAL mode for all steps to attach the barrel.
1. Unscrew and remove the barrel retainer from the adapter.
2. Put a tip cap on the syringe barrel and hold barrel next to the flexible cable assembly.
3. From MANUAL mode (Hand icon light on), advance the plunger by pressing the Forward button, just until the
plunger reaches past the piston.
4. By hand, insert the plunger into the barrel, pressing it snugly into the piston.
When the plunger fits into the piston, stop pressing Forward. If you continue, excess pressure can build inside the
barrel and may cause it to burst, resulting in serious injury.
WARNING
5. Press the Pullback button to retract the barrel until there is just a small gap between the barrel and the adapter.
6. Slide the barrel retainer over the barrel and thread one turn onto the adapter.
7. Replace the tip cap with a dispense tip. Tighten the barrel retainer.
8. Still in MANUAL mode, press the foot pedal to purge the dispense tip. Press until fluid almost fills the tip and
dispenses. Be sure not to overfill the tip since this results in excess back pressure, which can cause oozing.
NOTE:
See the handout provided with your Ultimus IV dispenser, “Syringe Barrel Attachment Guide,” for
simple, step-by-step instructions.
