Set the sample flow rate
Set the sample flow rate through the sample conditioning block. Set the
flow rate to 100–2000 mL/minute (500–1000 mL/minute is
recommended).
Measure the flow rate by putting the sample bypass drain tubing into a
large measuring container (flask or cylinder) over a set amount of time.
Collect the sample flow for 15 seconds, then multiply the collected
volume (mL) by 4 to identify the flow rate (mL/minute). Keep the end of
the sample bypass drain tubing no higher than the sample conditioning
block when the flow is measured.
Prepare Reagent 2 (HR hardness analyzer only)
Reagent 2 is supplied as a liquid and a powder that must be mixed
together before use. The approximate shelf life of the prepared reagent
is 3 months.
1. Remove the cap and seal from the Reagent 2 bottle. The seal can be
discarded.
2. Put the supplied powder funnel in the Reagent 2 bottle.
3. Add the powder to the liquid.
4. Install the original cap.
5. Hold the cap tight to prevent loosening and shake the bottle until the
powder is dissolved.

cleaning solution) in the bottle enclosures.
Put the bottles in the bottle enclosures as follows:
• Left enclosure: Reagent 1, Reagent 2, Reagent 3 (if present)
• Right enclosure: Standard 1, Standard 2, Cleaning solution
2. Remove the bottle cap and protective seal from each analyzer bottle.
3. Pick up the tube assemblies that go into the analyzer bottles. Make
sure that 12.7 mm (0.5-in.) of the tubing comes out of the bottom of
each straw.
4. Install the correct analyzer bottle cap and tube assembly on each
bottle. Each tube has a label that identifies the corresponding bottle.
Turn on the analyzer
1. Open the analyzer door.
2. Set the power switch to on. Refer to Product overview in the
