8.1.2 Solution Replacement

The analyzer has predictive capability that notifies when the
solutions require changing. For details of the reagent, clean and
calibration solutions, refer to Appendix A, page 64.
The analyzer is taken offline when solution replacement is in
progress.
Note. To prevent air getting into the reagent lines, ensure
the peristaltic pumps are switched off prior to lifting the
reagents lines out of the reagent bottles. This is done either
automatically by entering the solution replacement page or
manually through the Manual Test Settings menu.

8.1.3 Annual Service

The analyzer is taken offline and the pumps are stopped when
an annual service is in progress.
The annual service requires the pump tubing and all capstans to
be replaced. Once the service has been completed, the last
annual service date is reset and a purge routine is run
automatically. After each annual service, perform a manual clean
and, 6 hours later, a baseline calibration.
It is recommended that the pump tubing and pump capstans in
the annual pump refurbishment kit are replaced after one year of
operation.
