g.
If air is detected during Prime, the volume countdown will be reset to 100
ml again. Air in the disposable set is recirculated back to the reservoir
chamber and vented out the hydrophobic filter located on top of the
reservoir chamber or back into the fluid bags if both bag spikes have
pierced the fluid bag(s) and both bag clamps are opened. Heating occurs
during Prime. The prime sequence will stop automatically when
countdown reaches 0 ml. If after 30 seconds the countdown does not
decrease to at least 87 ml, the system will stop and prompt the user with
the Prime screen to unclamp the lines and restart the Prime.
h.
If Prime has to be stopped, press STOP. This does not bypass the full
prime. The prime volume countdown will remain on the screen. To
continue Prime, press RESUME PRIME. When the process is complete,
no air should remain in the main system fluid circuit.
CONTROLS
PRIME
Press the PRIME key to prime the reservoir, heat
exchanger, pressure chamber and tubing by
recirculating 100 ml of fluid at 500 ml/min through the
main flow path. A countdown of volume, from 100 ml
to 0 ml completes the prime, appears on the screen.
Fluid heating begins when the countdown reaches 60
ml.
THIS STEP IS IMPORTANT FOR PATIENT
SAFETY AND CANNOT BE BY-PASSED.
STOP
Stops the pump and places the system in standby,
ready to continue on request. But will not by-pass the
full Prime.
RESUME PRIME
Continues the priming process if the STOP key was
pressed during Prime.
