9. Remove the bottle cap and protective seal from the analyzer bottles.
10. Make sure that 12.7 mm (0.5-in.) of the tubing comes out of the

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.

Examine the sample conditioning block filter

If the sample condition block filter is removed from the instrument, make sure to
replace it with an alternative filtration system of 0.5 µm or smaller. Failure to
supply the required filtration will void the instrument warranty.
Unfiltered sample flows around the outside of the filter to continuously
self-clean the filter. Increase the sample flow to the sample conditioning
block as necessary to improve self-cleaning. Set the flow rate to
100–2000 mL/minute (500–1000 mL/minute is recommended).
