3.10.2 Periodically
• Check the alignment of the sampling arm needle. If the needle is not
centered in the inject port opening when it enters the port, realign the
needle using the Needle Alignment Wellness panel in Chromeleon or
Chromeleon Xpress (see Section 5.8
).
• Remove the drip tray (see Section 5.5), rinse the tray and the leak
sensor, dry thoroughly, and replace (see Section 5.6
).
• Check for leaks from the inject port, the syringe(s), the syringe
valve(s), and the sampling needle line. If leaks occur, see Section 4.2
.
• Monitor the usage of replaceable parts. The Chromeleon Wellness
panel displays the usage counters for the various parts. Replace or
service parts when recommended and reset the usage counter
afterwards (see Section 5.2.1
).
3.10.3 Annually
Perform the AS preventive maintenance procedure. An AS Preventive
Maintenance Kit (P/N 060581) is available for this purpose. The kit
provides parts and instructions for performing the procedure.
