8. Fill the arterial drip chamber to an acceptable level using the  key (level adjust) key on
the blood pump. Close the arterial pressure monitor line clamp and disconnect the line
from the arterial pressure port so the port is open to atmosphere.
Warning! The  Level Adjust key on the Blood Pump module can only be used to raise the
level in the arterial chamber. Do not press the Level Adjust key so long that the pressure
transducer protector becomes wet. Wet transducer protectors must be replaced to avoid
erroneous pressure readings.
9. The blood pump will start and continue to run until the pre-set amount of saline has been
flushed through the circuit. When blood pump stops, clamp the patient end of the venous
bloodline.
10. Insert the venous bloodline into the venous line clamp and optical detector on the level
detector module. Close the optical detector door.
Warning! The tubing beneath the venous drip chamber must be inserted into the venous line
clamp and the optical detector.
11. Adjust the fluid levels in the drip chambers by pressing the appropriate 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.
12. 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.
13. 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.
14. 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.
