  Matthew TaylorAug 18, 2025
  If the chlorine output meter needle is in the red zone on your compupool products Lighting Equipment, it could be due to a few reasons. First, the output dial might be turned up too high; try turning it down until the needle returns to the green zone. Secondly, the salt content might be too high; reduce the pool water salinity to 2500 – 3000ppm by backwashing the filter and adding fresh water. Finally, high pool water temperature can also cause this issue; in this case, turn the output dial down until the needle is back in the green zone.

  If you're experiencing low water flow through the cell in your compupool products Lighting Equipment, start by checking that the pump is operating correctly and turns on and off with the chlorine generator via the timer. Ensure that the pump strainer baskets are not clogged. Verify that all valves are opened correctly and check for any blockages. If the filter is dirty, clean or backwash it. For multi-speed pumps, increase the pump speed to ensure consistent and sufficient water flow through the Cell Housing.

  If you observe low or no chlorine residual in your compupool products Lighting Equipment, there are several potential reasons. First, ensure that the chlorine production dial is set to "High" to rule out insufficient chlorine output. Verify that the pool filtration pump and chlorine generator are running for sufficient operating hours. Check the stabilizer (cyanuric acid) level in the pool water and adjust to maintain a level of 30 – 60 ppm. Also, make sure the pH level is within the range of 7.2 – 7.8. If there was a heavy bather load, rain, or organic matter, allow the unit to run for a 24-hour period. Check the salt content and add salt to bring salinity to 2500 – 3000ppm. Inspect the cell for calcification or clogging and clean it. For high nitrates, phosphates or metals presence in po...

  If your compupool products Lighting Equipment shows low or no chlorine production, several factors could be responsible. Begin by ensuring the chlorine production dial is set to the "High" position. Confirm that the pump is running correctly and the Cell Housing is filled with water. Verify the salt content and add salt to the pool to achieve a salinity of 2500 – 3000ppm. Inspect the cell for calcification or clogging and clean it. Check if the circuit breaker has popped and reset it by pressing the yellow reset button. Examine the Cell Cable for any damage. Ensure the Cell Cable wires are correctly positioned (thin wire in the middle) at the junction box and firmly tightened. If none of these steps resolve the issue, the Electrolytic Cell may be nearing the end of its life and require rep...
