Instructions for PS234 test kit

>CHLORINE DROP-COUNT (FAS/DPD TEST (record as ‘FC’ and/or ‘CC’ above)

1. Rinse and fill clear chlorine test tube to the 10 ml mark on the side.
2. Add 1 scoop of FAS-DPD #1 powder and swirl. (Don’t worry if some remains undissolved)
3. Carefully add drops of FAS-DPD #2 reagent, 1 drop at a time. Be sure to use #2, not #3. Swirl after each drop. Continue until the pink color disappears. Divide the number of drops by 2 for your FREE chlorine reading. (10 drops = 5 ppm free chlorine). Chart in the “FC” box.
4. To test combined chlorine, continue by adding 5 drops of FAS-DPD #3 potassium iodide solution & swirl to mix. If the sample remains clear, you have no combined chlorine.
5. Otherwise, add drops of FAS-DPD #2 reagent as before, until the color disappears. Divide number of drops by 2 for COMBINED chlorine reading. Chart in the “CC” row, NOT the TC row. NOTE: FC + CC = TC. FAS – DPD TC readings will not match OTO readings exactly.

>DAILY CHLORINE COLOR COMPARATOR (OTO) TEST (‘TC’)

1. Rinse and fill yellow-side tube of the test block with pool water to line.
2. Add 5 drops R-0600 OTO solution. Cap and invert to mix.
3. Match color with chlorine color standard. – be careful of background. Chart as TC.
NOTE: OTO testing is less accurate, but very reliable. If there is no yellow color, after adding OTO, you have NO chlorine of any kind. If the solution turns orange, check with FAS-DPD to make sure level is below 20 ppm. If the solution turns brown, do NOT swim – chlorine levels are above 50 ppm, and will damage suits and may irritate skin!

>pH TEST (record as ‘pH’)

1. Rinse and fill pH (reddish) side tube of test block with pool water to line.
2. Add 5 drops R-0014 phenol red solution. Cap and invert to mix.
3. Match sample color with pH color standard.
4. If the chlorine level is above 15 ppm wait till the chlorine drops before testing.
NOTE: for OTO & pH testing, use white inside label as background.

>TOTAL ALKALINITY TEST (TA, alkalinity – Record as ‘Alk’)

1. Rinse and fill large comparator tube to the 25 ml mark with pool water.
2. Add 2 drops ALK #1 & swirl to mix. Add 5 drops ALK #2 indicator & mix. Sample should turn green.
3. Add ALK #3 one drop at a time, swirling between drops. Continue adding drops till sample changes from green to red. Multiply the number of drops of ALK #3 used by 10. Record this reading as “Alk”.
NOTE: colors may 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.

>CALCIUM HARDNESS TEST (CH, hardness – record as ‘Cal’)

1. Rinse and fill large comparator tube to the 25 ml mark with pool water.
2. Add 20 drops CAL#1 and mix. Add 5 drops CAL #2 and mix. A red color indicates calcium’s presence.
3. Add CAL #3 one drop at a time, swirling after each drop. Continue till color changes to blue.
4. Multiply number of drops by 10. This is your calcium hardness reading. Record as “Cal”.
5. On pools with ionizers, ‘mineral tabs’, Nature2, Pristine Blue, or copper algaecides, add TWO drops of CAL #3 BEFORE adding Cal #2. Include these drops in your count.

>CYANURIC ACID TEST (stabilizer, conditioner – record as ‘Cya’)

1. Rinse, empty & fill the CYA dispensing bottle to the 1st line mark with pool water.
2. Fill with CYA#1 reagent to the 2nd line. Cap, mix & wait 30 seconds.
3. Get the clear tube, marked “C.A. VIEW TUBE”, and hold it at waist level in outdoor light. 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 completely when viewed from the top.
4. If the black dot never disappears, you have ZERO stabilizer. If it disappears instantly, your stabilizer level is greater than 150 ppm. Otherwise raise the tube to eye level, find the scale on the side of the tube, marked 100 at the lowest point and 20 at the highest.
5. Read the liquid level in the tube against the scale. This is your CYA level.

>GETTING GOOD RESULTS

1. ALWAYS rinse the test cells with pool water BEFORE beginning testing.
2. ALWAYS rinse the test cells with clean pool water or tap water AFTER finishing your tests.
3. ALWAYS recap the reagent bottles promptly. Both the DPD powder (FASDPD #1) and the FAS drops (FASDPD #2) need to be tightly capped.
4. NEVER collect your water sample from the surface of the pool. Fully submerge the collection vessel upside down before allowing pool water to enter.
5. NEVER leave your PS234 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.
6. When using the color match pH or OT chlorine tests, the color of the background will affect your ability to read the results. Best results will come from using a white sunlit (or sky lit) light surface as background. The inside label of the pS200 is there for exactly this purpose, but do not place the testblock directly against the lid label. Hold it at least 2” away from the label. Avoid strongly colored backgrounds, such as green trees or lawn, or blue sky.



IMPORTANT
1.Keep DPD powder DRY!!
2.Use only 1 dipper full of powder.
3.Use a completely dry dipper: allow a wet dipper to dry COMPLETELY
Before re-using
4.If powder turns medium gray or darker order a replacement.
