Observe the wash probe spray pattern during the prime. There should be three distinct and
straight streams in a triangular pattern spraying from each probe.
NOTE
If a pattern of distinct streams is not observed during prime, check for proper water pressure in
the hydropneumatic system. If the water pressure is adequate, check the probe tips for broken glass.
6
When the priming has stopped, turn the wash station to check the tips of the probes for
obstructions. Check for debris like glass from the cuvettes or resin beads, which can cause a
blockage of the probes. Manually remove any obstruction. You can use a small can of
compressed air to remove the blockage by blowing air through the probes from the probe top.
If you cannot remove the blockage, contact Beckman Coulter Support Center for instructions
on how to replace cuvette washer probes.
7
Place each of the first three wash probes into three 13 × 100 mm test tubes (one probe per test
tube). Be careful to keep the probes above the surface of the liquid.
