10. Run the blood pump to flush saline through the circuit until a fluid level is detected in the
venous drip chamber. The blood pump will stop when the level detector senses a level of
fluid.
11. Press the RESET key on the control panel to restart the blood pump and continue
flushing saline through the blood circuit in accordance with established facility protocol
regarding dialyzer rinsing.
12. After the required saline amount has passed through the circuit, press the Start/Stop key
on the blood pump to stop the pump.
13. Clamp the patient end of the venous bloodline.
14. Adjust the fluid levels in the drip chambers by pressing the appropriate  or  level
adjust keys. Close the venous pressure monitor line clamp and disconnect the monitor
line from the venous pressure port so the port is open to atmosphere.
15. Aseptically connect the patient end of the arterial bloodline to the patient end of the
venous bloodline using a sterile recirculation piece. Unclamp both lines.
16. Set the blood pump rate to 350-400 ml/min. Press the blood pump Start/Stop key to
start the pump and begin recirculation. If necessary, press the RESET key to clear any
alarms.
17. Ensure that the extracorporeal circuit is free of air bubbles.
Note: The dialysate lines will have to be attached at the appropriate point during the priming
process, depending on facility procedure and manufacturer's instructions. If 1.5x or 2x
dialysate flow (Auto Flow) is selected, be sure that the dialysate flow rate is at least the
minimum required rate.

Prime Amount Method

1. Connect the dialyzer end of the arterial bloodline to the arterial port of the dialyzer.
Rotate the dialyzer to the arterial end down position.
2. Connect the dialyzer end of the venous bloodline to the venous port of the dialyzer.
3. Hang a saline bag and attach an administration line, if not already attached, to the saline
port on the arterial bloodline. Aseptically spike the saline bag.
4. Gravity prime the patient end of the arterial bloodline below the saline "T" with saline.
When primed, clamp off the patient end of the arterial bloodline.
5. If the heparin pump is to be used: connect the heparin syringe, prime the heparin line
with heparin, and load heparin syringe into heparin pump. If the heparin pump is not
used, clamp the heparin line.
6. On the control panel keypad, press the Prime key.
7. Press the blood pump Start/Stop key and run the blood pump at a rate of 150 ml/min.
Adjust the flow rate by pressing the  (up) or  (down) keys.
