Replacing The Diaphragm Pumps - Siemens ADVIA 2120 Operator's Manual

5. Wet the new clot filter with water and place it into the filter adapter fitting.
Orientation of the filter is not important.
6. Reconnect the filter adapter fitting to the selector valve. Finger tighten.
IMPORTANT
Be very careful not to misthread the fitting. Misthreading could strip the
valve which will prevent proper operation.
7. Run a sample and visually check for air bubbles in the sample line between
the selector valve and the UFC block.
8. Check aspiration rate.
9. If air bubbles appear, check that the filter adapter fitting is screwed on
correctly and that it is finger-tight, then repeat step 7. If air bubbles still
appear, disconnect the filter adapter fitting and check for dust or debris in the
fitting and in the port.
If air bubbles still persist, call Siemens technical support.
