before any connection to avoid particle injection into the hydraulic system. If particulate matter is
present in the sample, pre-filtration is necessary. A filter should be inserted in the sample line. One is
available as an option.
Connecting the drain tube
The drain outlet is located on the bottom of the analyzer. A 12 x 17 mm pipe is delivered with the
analyzer and should be connected to the drain outlet at one end and the other fed to a drain for
sample evacuation.
Reagents installation
The canisters are installed in the canister holder (No. 10 in
1. Prepare the reagents.
2. Install and connect the conditioning solution (diisopropylamine).
3. Install and connect the reactivation solution (blue R label).
4. If you have this option, install and connect the auto calibration solution
(yellow CAL label).
Magnetic stirrer installation
1. On the front of the panel, remove the plastic bag from the overflow vessel (No. 5 in
on page 6).
2. Remove the magnetic stirrer from the bag and install it in the overflow vessel.
Reagents volume declaration
Note: As you will now be using the analyzer menus to input data, it may be useful to familiarize yourself with the
data entry procedures by reading the section entitled

3. Check that there are no air bubbles in the reagent tubes for reactivation and auto calibration.
4. The next step allows you to regulate the sample flow rate on the measurement channel.
5. The analyzer automatically empties and refills the overflow vessel to determine the flow rate
which is displayed on screen.
6. The flow rate should be 6 to 9 L/hour.
7. Using a screwdriver, regulate the channel's sample flow (No. 3 in
counter-clockwise to increase the flow rate or clockwise to decrease the flow rate.
8. The process is repeated until the flow is correctly regulated for the channel. At this point select
OK.
9. On completion, an Action completed message will be displayed. Select Esc to exit.
