Maintaining the Analyzer 4-15
CAUTION
After repositioning the aspirator assembly, finger-tighten the thumb screws,
being careful that they are not cross threaded. Overtightening of the screws
can warp the baseplate, which will cause misalignment of the sampler. Mis-
threading the thumb screws can cause needle damage.
10. Place the tubes going to the autosampler centering collar into the "hook" on
the side of the IDee reader.
11. Close the front cover.
12. Run saline and whole blood primers to verify system performance.

To replace the sheath filters
1. Carefully pull the filter toward you just enough to
remove it from its mounting and gain access to the
tubing. Place paper towels under the filter to catch
any fluid that leaks out when you remove the filter.
