Maintaining the Analyzer 4-5
6. Attach a piece of 0.030-inch ID tubing to a syringe, then flush each port on
the autosampler collar or the waste port on the manual closed-tube sampler
collar with water.
IMPORTANT
To prevent autosampler centering collar lock ups, apply Parker
Super O-lube (or equivalent lubricant) to the barrel part (
1 ) of
the centering collar.
Do not get lubricant near the needle port or the needle base ( 2 ).
NOTE
The dual Autosampler has two centering collars, one for
analyzer sampling and one for optional Autoslide sampling.
Both Centering collars use the same cleaning method.

8. Remove the needle cover and carefully replace the collar over the needle. On
the autosampler centering collar, be sure to turn the spring-loaded knob back
to its original position.
9. On the autosampler, reposition the autosampler aspirator assembly. Make
sure that it drops firmly in place over the guide pins, then reconnect the
sample line to the base of the centering collar.
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. Snap the manual-sampler centering collar into place.
12. Close the analyzer cover.
13. Turn on the analyzer power.
14. Check saline background count and run whole blood primers to verify system
performance.
