B.3.8 Installing the Sampling Needle
The AS-HV is shipped with a PEEK Sampling Needle Kit (P/N 064511).
An optional Sampling Needle Kit–PTFE Lined and Sleeved (P/N 064056)
is available, also.
1. Check that the power to the AS-HV is off.
2. Manually rotate the sampling arm so that it can be easily worked on.
3. Move the Z-axis slide to the top of the carriage (see Figure B-6 ).
4. Slide the sampling needle mounting block into the Z-axis slide,
ensuring that the sampling needle (PEEK Sampling Needle Kit,
P/N 064511; Sampling Needle Kit–PTFE Lined and Sleeved,
P/N 064056) passes through the accessories plate, and secure it with
the knurled mounting nut (see
Figure B-6 ).
5. Screw the sampling needle guide (P/N 064519) onto the underside of
the accessories plate.
NOTE The sampling needle guide ensures that the
PEEK needle does not bend or flex as it pierces
the septum in the sample container cap.
To avoid injury, always turn off the power to the AS-HV before
installing or removing the sampling needle.
Afin d'éviter toute blessure, couper impérativement l'alimentation
secteur avant d'installer ou de démonter l'aiguille de prélèvement.
Um Verletzungen zu vermeiden, schalten Sie den AS-HV bitte immer
aus, ehe Sie die Probennadel installieren oder deinstallieren.
