6.1 Commissioning the Analyzer
Refer to Appendix A for details of reagents, calibration solutions
and cleaning solutions.
Before operating the analyzer:
1. Ensure the analyzer has been installed correctly – see
2. Ensure all reagent, calibration and cleaning solution
bottles are filled with the appropriate solutions.
3. Ensure the reagent bottles are mounted safely and
securely in the trays* (if supplied) and the bottle tops are
fitted securely.
*These accessories are not included with all models.
6.1.1 Start-up and Configuration
The following steps describe briefly how to start up and
configure the analyzer prior to operation:
1. Clip the pump plattens into place.
2. Ensure at least one sample stream is connected and
flowing.
3. Ensure the drain tube from the analyzer is:
a. connected and directed to a drain
b. as short as possible and routed as vertically as
possible.
4. Switch on power to the analyzer.
5. After the initial power up procedure a message is
displayed asking if the 'Power Up Sequence' should be
aborted. Select 'Stop' to abort the automatic start up.
6. Check that the failure icon (
) is
not
displayed in the
diagnostic window. If it is displayed, resolve the cause of
the failure before proceeding.
7. Purge the zero calibration line, secondary calibration and
clean solution lines as follows:
a. Press the
key, select 'Calibration & Maintenance'
and select the 'Manual Test Settings' button.
b. Select 'Test Pumps' and increase the sample pump
speed to 5 rpm using the key pad.
c. Exit the 'Test Pumps' page and enter the 'Test Valves'
page.
d. Select 'Cleaning ON' to energize the clean valve.
Leave on for at least 1 minute to flush the clean
solution line.
e. De-energize the clean valve and energize the
secondary calibration valve in the 'Test Valves' page.
Leave on for a least 1 minute to flush the secondary
solution line.
f.
De-energize the secondary calibration valve and
energize the zero cal valve. Leave on for at least 1
minute.
g. Once all lines have been flushed, select 'Normal Mode'
to exit 'Manual Test Settings'. The analyzer returns to
the correct pump speed and de-energizes the valves.
h. A recovery period is initiated (this can be dismissed to
access the menu).
8. Press the
key, select 'Calibration & Maintenance' and
select 'Solution Replacement'. Select 'Replace Cleaning
Solution' and then 'Replace Secondary Cal Solution' – this
updates the dates they were installed.
9. Select 'Replace All Reagent Solutions' – this initiates a
purge sequence followed by a recovery sequence that
enables the analyzer to stabilize.
10. Initiate a Manual Clean procedure.
At this stage a baseline calibration must be performed.
Warning.
Protective eye wear and protective hand wear must be worn
when contact with chemicals is possible. Take appropriate
Health & Safety precautions.
Note.
The analyzer reading takes some time to settle after
the initial Commissioning procedure – this is due mainly to
the gradual wetting of the internal plastic flow path.
Therefore, if an accurate calibration is required it is advisable
to wait several hours before initiating a calibration.
