7.
Turn on the console, and set the speed to approximately 1500 RPMs with the clamps still on the drainage and return tubing in
the basin.
8.
Remove the clamp from the drainage tubing and then remove the clamps from the return tubing. Allow the priming solution to
recirculate until all visible air is removed.
CAUTION: Ensure that the open ends of the tubing segments remain submerged during recirculation to avoid air
entrainment.
9.
Inspect the circuit to ensure all air has been removed. If there is residual air, continue to run the pump with the open ends of
the tubing in the basin to complete the de-airing process.
CAUTION: If air is entrained in the pump head, turn the set speed to zero, and then walk the air bubble out of the pump.
10.
Replace the clamps on the inflow and outflow tubing in the basin. The circuit is now ready for use.
Submersion Technique – Wet connection
The wet connection submersion technique should be performed using aseptic techniques. To prime the pump:
1.
Fill a large sterile basin with three liters of a warm balanced electrolyte solution.
2.
Slowly submerge one end of the drainage tubing segment, then gradually submerge the entire piece, allowing the tubing to fill
completely from one end to the other, remaining under the surface at all times. Clamp both ends of the tubing segment once all air
has been dispelled and tubing is primed. Repeat for the return tubing segment.
CAUTION: The CentriMag pump may magnetically attract to a metal basin. Use caution if a metal basin is used.
3.
Open the pump package. Submerge the pump in the saline, rotating from side to side to ensure complete removal of air.
CAUTION: The outside of the pump packaging is not sterile.
4.
Remove the clamp from one end of the drainage tubing segment and then connect it to the inflow of the pump. Remove the
clamp from one end of the return tubing segment and then connect it to the outflow of the pump. Ensure that all of the
connections are made while the components are fully submerged.
