Priming
The AS performs the following operations during priming:
•
The sampling needle arm moves to the waste port and expels any
fluid from the needle.
•
The sampling needle arm moves to the flush port and delivers a
volume of flush fluid. This primes the lines from the flush reservoir to
the syringe and through the sampling needle assembly (see
Figure 2-22 ).
When the sample preparation option is installed, additional priming is
required to prime the lines from the reagent reservoir(s) to the sample
syringe (see
Figure 2-24 ). See Section B.3.13 for instructions on priming
the liquid lines.

Figure 2-22 shows the fluid connections to the sample syringe and flush
reservoir when no sample prep option is installed.
