8. Alarms and Troubleshooting Guide
8-108
• If the Reprime volume count does not count down from 100 to 0 ml, check
and make sure that:
• The bags are fully spiked and clamps are fully opened.
• The pump tubing is filled with fluid, is not stretched and is seated firmly
within the Fluid Out sensor (open the door to fill tubing with fluid, if
necessary.)
• Fluid Out sensor is clean and there is nothing obstructing contact with the
sensor.
REPRIMING THE MAIN SYSTEM FLUID CIRCUIT WHEN THE RESERVOIR
REMAINS EMPTY AFTER EXTENSIVE OPERATION
• If the Reprime procedure cannot be completed or the reservoir chamber stays
empty after a Reprime, the hydrophobic air vent filter on top of the reservoir
chamber may be clogged by blood particulates. Under this condition, air in the
reservoir chamber can be forced back into the fluid bag by using procedure
below:
Pierce both bag spikes into separate fluid bags and open both clamps to
allow the air in the reservoir chamber to escape into one of the fluid bags.
Press REPRIME to recirculate the fluid in the disposable set to remove air
remaining in the disposable set.
• Inspect the disposable set and patient line to make certain that there is no air.
• If the air could not be returned into the fluid bag, either replace reservoir
chamber or restart the system and replace the disposable set and proceed with
the original prime.
