PS232 Label Instructions

PS232 Box-label Instructions

Rinse and fill large clear tube with the white lid to the 10 ml mark on the side.
Add 2 scoops of DPD powder (R-0870) and swirl. (If 1 scoop turns the water pink, you don�t need more.)
Carefully add drops of R-0871 FAS-DPD reagent, 1 drop at a time. Be sure to use R-0871. Swirl after each drop. Continue until the pink color disappears. Multiply the number of drops by 0.5 for your FREE chlorine reading. (10 drops = 5 ppm free chlorine). Chart in the �FC� box.
To test combined chlorine, continue by adding 5 drops of R-003 and swirl. If the sample remains clear, you have no combined chlorine.
Otherwise, add drops of R-0871 as before, till the color disappears. Multiply the number of drops by 0.5 for your COMBINED chlorine reading. Chart in the �CC� row, NOT the TC row.

Rinse and fill small comparator tube of the large test block with pool water to the 9 ml mark.
Add 5 drops each of R-0001 and R-0002. Cap and invert to mix.
Match color with chlorine color standard. -- be careful of background. Chart as FC.
To test for total chlorine, continue by adding 5 drops R-0003. Cap and invert to mix.
Match color immediately, and record reading as TC, and NOT CC. CAUTION: this test is not accurate above 5 ppm, and may read �0� when chlorine levels reach 15 ppm or higher.

Rinse and fill large comparator tube to the 44 ml mark with pool water.
Add 5 drops R-0004. Cap and invert to mix.
Match sample color with pH color standard. If sample is between two colors, reading is the average.
If the chlorine level is above 12 ppm, first add ONE drop only R-0007 thiosulfate reagent from the alkalinity test group, and mix, before adding the R-0004.

1. Rinse and fill large comparator tube to the 25 ml mark with pool water.
Add 2 drops R-0007 and swirl to mix. Add 5 drops R-0008 and swirl. Sample should turn green.
Add R-0009 one drop at a time, swirling between drops. Continue adding drops till sample changes from green to red. Multiply the number of drops of R-0009 use by 10. Record this reading as �Alk� NOTE: colors make go from blue to yellow (instead of green to red) if oxidizer levels (peroxide, oxy-shock, chlorine or bromine) are high. This does not invalidate the test.

Rinse and fill large comparator tube to the 25 ml mark with pool water.
Add 20 drops R-0010 & mix. Add 5 drops R-0011L & mix. A red color indicates calcium�s presence.
Add R-0012 one drop at a time, swirling after each drop. Continue till color changes to blue.
Multiply number of drops by 10. This is your calcium hardness reading. Record as �Cal�.
On pools with ionizers, �mineral tabs�, Nature2, Pristine Blue, or copper algaecides, add TWO drops of R-0012 BEFORE adding R-0011L. Count these drops in your reading.

Rinse and fill the flip-top CYA dispensing bottle to the 7 ml mark with pool water.
Add R-0013 to the bottle, to the 14 ml mark. Cap, mix, and wait 30 seconds.
Rinse the small comparator tube on the testblock. Hold the test block at waist level in outdoor light, and slowly fill the small comparator tube with the mix from the CYA dispensing bottle, just until the black dot at the BOTTOM of the tube disappears when viewed from the top.
If the black dot never disappears, you have ZERO stabilizer. If it disappears instantly, your stabilizer level is greater than 150 ppm.
Otherwise, turn the test block around, and find the scale on the side of the small tube, marked 100 at the lowest point, and 30 at the highest. Read the liquid level in the tube against the scale.

ALWAYS rinse the test cells with pool water BEFORE beginning testing.
ALWAYS rinse the test cells with clean pool water or tap water AFTER finishing your tests.
ALWAYS recap the reagent bottles promptly. In particular, the FAS/DPD reagent (R-0871) can be rendered inaccurate if left open for as little as � hour!
NEVER collect your water sample from the surface of the pool. Fully submerge the collection vessel upside down before allowing pool water to enter.
NEVER leave your PS232 at pool side in the sun, or in a hot pump house or garage. Store it indoors. Instead, use the inexpensive PS200 as a quick poolside tester!
When using the color match pH or DPD-chlorine tests, the color of the background will affect your ability to read the results. Best results will come from using a sunlit (or sky lit) light surface as the background. You may be able to use the top label of the PS232 for this purpose, but do not place the testblock directly against the lid label. Hold it at least 6� away from the label. Avoid strongly colored back grounds, such as green trees or lawn, or blue sky.
