control unit and that the wire is not cut or damaged. Make sure you have at least 12" of straight pipe before the flow switch. If there is adequate flow and the LED is still on, check that the arrows on the flow switch (on top of hex) are pointing in the direction of flow. 6. "Test Salt Level" LED illuminated or flashing Take a sample of your pool water to your local Authorized Aqua Rite Dealer and have the salt level tested. No salt test is completely accurate and the test results may vary from the salt level on the Aqua Trol display. If salt level is low, add salt according to chart on page 4. 7. "High Salt" LED illuminated Check salt level in pool/spa. If salt level is too high, lower salt level by draining some of the pool water out of the pool and replace with fresh water. Continue until the salt concentration is at recommended levels. 8. "Inspect Cell" LED flashing Inspect and clean cell according to directions on page 8. When done, press the "diagnostic" button for 3 seconds to stop the "Inspect Cell" LED flashing. 9. "Inspect Cell" LED illuminated Remove and inspect the cell for scale. If the cell is scaled, follow the directions on page 8 for cell cleaning. If the pool has the proper amount of salt and the "Inspect Cell" LED is still illuminated, the cell may be worn and need replacement. 10. Possible causes of little or no free chlorine residual - Aqua Trol switch in OFF position. - Desired Level % adjustment setting is too low. - Low stabilizer (Cyanuric Acid). - Filter pump switched off or filter pump time too short (8 hours for average size pools, more for large pools) - Salt level too low (below 2500 ppm, Low Salt LED on). - Salt level too high (High Salt LED on). - Very warm pools increase chlorine demand--increase Desired Level % or filter run time. - Cold water (below 50F) causes Aqua Trol to stop generating (Generating LED flashing). - Excessive scaling on cell. - High level of Nitrogen in pool water. - "Yellow Out" or similar treatment recently used. Some yellow algae treatments will use chlorine at a very high rate and deplete the residual free chlorine. Manually shock the pool if indicated in the directions on the algae treatment. It still may be a matter of days before the pool returns to "normal" and chlorine tests will show the desired 1-3ppm free chlorine reading. 11. "-Pcb-" displayed and all 4 red/yellow LEDs are illuminated. A possible Printed Circuit Board fault has been detected. 14
