The Aspiration Needle in the Tower Module should be cleaned regularly to remove
protein buildup or debris and reduce the possibility of a blockage. The procedure
for cleaning the needle differs slightly on the CS and SL models. Both procedures
are described below.
WARNING: Potential Biohazard. The needle in the Tower Module is
sharp and potentially contaminated with infectious materials. Avoid any
contact with the needle.
1. CELL-DYN Enzymatic Cleaner
2. Diluent
3. Three empty VACUTAINER
4. Gloves, lab coat, and safety glasses
1. Aliquot approximately 2 mL of Enzymatic Cleaner into one of the
VACUTAINER ® tubes.
2. Aliquot approximately 2 mL of diluent each into the other two
VACUTAINER ® tubes.
3. If necessary, press the [CHANGE SAMPLER] soft key in the RUN screen to
select the Closed Mode.
4. In the RUN screen, press [SPECIMEN TYPE] followed by [BACKGROUND]
5. Place the enzymatic cleaner tube followed by the two diluent tubes in a
Sample Loader rack.
NOTE: A convenient way to perform this procedure is to add the tubes to
the end of the last run of the day.
6. Position the rack on the load side of the Sample Loader (refer to Figure 13.7
if necessary). Make sure the Tower Cover is closed.
CAUTION: The Sample Loader will not operate unless the Tower Cover
is in place.
7. Press the [START LOADER] key to initiate processing.
8. Audible beep tones indicate that processing is completed.
9. Run at least three background counts to rinse the system. Check that the
background counts are acceptable before running controls or patient samples.
If the counts are unacceptable, troubleshoot accordingly (refer to Section 10:
Troubleshooting and Diagnostics; Subsection: Troubleshooting Guide).
10. When cleaning is completed, remain in the RUN screen to process patient
samples or press [MAIN] to return to the MAIN MENU.
