4. Setup
The Pentair R151076 test kit requires minimal setup. Upon receiving your kit, ensure all components listed in Section 3 are present and undamaged. Familiarize yourself with the color comparison charts on the test vial assembly for both pH and Chlorine readings.
5. Operating Instructions
Follow these steps for accurate testing of your pool or spa water:
- Step 1: Collect Water Sample
Submerge the dual test vial assembly into your pool or spa water to elbow depth, away from return jets. Fill both vials to the indicated fill line. - Step 2: Add Reagents
- For Chlorine (CL) Test: Add 5 drops of OTO (Orthotolidine) Solution to the vial marked 'CL'.
- For pH Test: Add 5 drops of Phenol Red Solution to the vial marked 'pH'.
- Step 3: Cap and Mix
Securely cap both vials. Invert the test kit several times to thoroughly mix the water samples with the reagents. - Step 4: Read Results
Hold the test kit against a white background in natural light. Compare the color of the water in the 'CL' vial to the Chlorine color comparator (range 0.3 - 3.0 ppm). Compare the color of the water in the 'pH' vial to the pH color comparator (range 7.2 - 8.2). The ideal chlorine range is typically 1.0 to 1.5 ppm, and the ideal pH range is 7.4 to 7.6. - Step 5: Rinse After Use
After recording your results, empty the vials and rinse them thoroughly with clean water. Cap the vials and store the kit in its case.
6. Maintenance
- Rinse test vials thoroughly after each use to prevent residue buildup and ensure accurate future readings.
- Store the kit in a cool, dry place, away from direct sunlight and extreme temperatures, to prolong the life of the reagents.
- Check reagent expiration dates periodically. Replace reagents as needed to ensure accuracy.
7. Troubleshooting
- Inaccurate Readings: Ensure vials are clean and free of residue. Check reagent expiration dates. Ensure proper lighting when reading results (natural daylight is best, avoid direct sunlight).
- No Color Change: Verify that reagents were added correctly and in the specified amount (5 drops per vial). Ensure the water sample was collected properly.
- Cloudy Sample: Ensure the water sample is free of debris. If water is excessively cloudy, allow it to settle or filter before testing.
