Put the analyzer in shutdown mode
Stop the analyzer before maintenance tasks are started. When the analyzer is stopped, the
colorimeter cell is flushed, then the sample flow, mixer motor, air pump and heater turn off. The
controller menus stay active.
1. Push menu.
2. Select STOP ANALYZER, then YES to confirm.
Note: If START ANALYZER is shown, the analyzer is already in shutdown mode.
3. Wait for the status to show 100% completion.
4. Close the shut-off valves in the sample lines, then complete the maintenance task(s).
Put the analyzer back into operation
After maintenance tasks are complete, start the analyzer.
1. Make sure that all the tubing is connected and that the lower door is closed and latched.
2. Open the shut-off valves in the sample lines.
3. Push menu.
4. Select START ANALYZER.
The analyzer starts normal operation.
Clean the instrument
N O T I C E
Never use cleaning agents such as turpentine, acetone or similar products to clean the instrument including the

Clean spills
CAUTION
Chemical exposure hazard. Dispose of chemicals and wastes in accordance with local, regional and
national regulations.
1. Obey all facility safety protocols for spill control.
2. Discard the waste according to applicable regulations.
Sample line and valve cleanup
CAUTION
Chemical exposure hazard. Obey laboratory safety procedures and wear all of the personal protective
equipment appropriate to the chemicals that are handled. Refer to the current safety data sheets
(MSDS/SDS) for safety protocols.
New tubing, valves and other sample conditioning equipment may be contaminated with silicate-
based substances (oils, dust). These may contribute to slightly high readings until they are cleaned.
1. Flush the sample line with sample for one to two hours.
2. For an expedient procedure, inject one to four liters of a dilute caustic solution such as 1N (5%)
sodium hydroxide solution into the front end of the sample line. Force the solution through the
analyzer to clean sample system components.
Clean the sample cell
CAUTION
Chemical exposure hazard. Obey laboratory safety procedures and wear all of the personal protective
equipment appropriate to the chemicals that are handled. Refer to the current safety data sheets
(MSDS/SDS) for safety protocols.
Put the analyzer in shutdown mode. Refer to Put the analyzer in shutdown mode on page 4.
Clean the sample cell in the colorimeter as needed. Refer to Figure 1 and Figure 2.
Items to collect:
• Cotton swabs, wooden or paper. Do not use swabs with plastic sticks.

applicable reagent delivery valve.
The quantity of reagent that is supplied
to the sample cell is incorrect.
Complete the diagnostic test for reagent delivery.
Refer to Diagnostic test for reagent delivery
on page 11. If the reagent delivery is incorrect,
look for a blockage in the tubing or replace the
applicable solenoid valve.
The quantity of calibration solution that
is supplied to the sample cell is
incorrect.
Complete the diagnostic test for calibration solution
delivery. Refer to Diagnostic test for calibration
solution delivery on page 12. If the calibration
solution delivery is incorrect, look for a blockage in
the tubing or replace the applicable solenoid valve.
The stir bar is not installed correctly or
does not move.
Note: The stir bar moves intermittently during
measurements.
Install the stir bar. Make sure that the stir bar moves
during measurements.
The instrument
reading is low or
less than zero.
