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.

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.
1. Put the supplied analyzer bottles (reagent, standard solution and
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
Installation manual for the power switch location.
3. Close the analyzer door and close the door latches. Keep the
analyzer door closed during operation so that the temperature control
system operates correctly.
Prime the analyzer
Make sure to plumb the sample lines and drain hoses and install the
reagent and standard bottles before this task is started.
