Attach Barrel/Purge 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.

5. Press the Pullback button to retract barrel, until there is just a small gap between barrel and

adapter.

6. Slide barrel retainer over the barrel and thread one turn onto the adapter.

7. Replace tip cap with dispense tip. Tighten barrel retainer.

8. Still in MANUAL mode, press the foot pedal to purge 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 Ultra 2800 dispenser, Syringe Barrel Attachment

Guide, for simple, step-by-step instructions.

Removing the syringe barrel

1. Press F1 to get the Retract to Home screen. Select Yes. This will retract the plunger into the

cable assembly.

2. Unscrew the barrel retainer from the adapter.

3. Slide the syringe barrel off the plunger.

4. Discard the barrel, or if storing for later use, replace the dispense tip with a tip cap.

5. Screw the barrel retainer back onto the adapter.
