Hayward AquaRite® 120 Operation Manual - Page 9

The Aqua Rite electrolytic cell has a self cleaning feature incorporated into the electronic control's logic. In most cases this self cleaning action will keep the cell working at optimum efficiency. In areas where water is hard (high mineral content) and in pools where the water chemistry has been allowed to get "out of balance", the cell may require periodic cleaning. The "Inspect Cell" LED will indicate if cell efficiency is decreased and servicing is necessary. If the "Inspect Cell" LED remains on after a thorough cleaning, the cell may be worn and require replacement. Servicing and Cleaning the Aqua Rite cell Turn off power to the Aqua Rite before removing the electrolytic cell. Once removed, look inside the cell and inspect for scale formation (light colored crusty or flaky deposits) on the plates and for any debris which has passed through the filter and caught on the plates. If no deposits are visible, reinstall. If deposits are seen, use a high pressure garden hose and try to flush the scale off. If this is not successful, use a plastic or wood tool (do not use metal as this will scratch the coating off the plates) and scrape deposits off of plates. Note that a buildup on the cell indicates that there is an unusually high calcium level in the pool (old pool water is usually the cause). If this is not corrected, you may to have to periodically clean the cell. The simplest way to avoid this is to bring the pool chemistry to the recommended levels as specified. Mild Acid Washing: Use only in severe cases where flushing and scraping will not remove the majority of deposits. To acid wash, turn off power to Aqua Rite. Remove cell from piping. In a clean plastic container, mix a 4:1 solution of water to muriatic acid (one gallon of water to one quart of muriatic acid). ALWAYS ADD ACID TO WATER NEVER ADD WATER TO ACID. Be sure to wear rubber gloves and appropriate eye protection. The level of the solution in the container should just reach the top of the cell so that the wire harness compartment is NOT submerged. It may be helpful to coil the wiring before immersing the cell. The cell should soak for a few minutes and then rinse with a high pressure garden hose. If any deposits are still visible, repeat soaking and rinsing. Replace cell and inspect again periodically. Winterizing The Aqua Rite electrolytic cell and flow detection switch will be damaged by freezing water just as your pool plumbing would. In areas of the country which experience severe or extended periods of freezing temperatures, be sure to drain all water from the pump, filter, and supply and return lines before any freezing conditions occur. The electronic control is capable of withstanding any winter weather and should not be removed. Spring Start-up DO NOT turn the Aqua Rite on, until the pool water chemistry has been brought to the proper levels. This information can be found on page 1. 9 Controls Main Switch AUTO: For normal operation, the Main Switch should be left in the AUTO position. In this position the Aqua Rite will produce chlorine according to the "Desired Output %" adjustment setting for the entire filtering/pumping cycle. SUPER CHLORINATE: When you have an abnormally high bather load, a large amount of rain, a cloudy water condition, or any other condition which needs a large amount of purification to be introduced, put the Main Switch in the SUPER CHLORINATE position. This electronically "super chlorinates" (shocks) the water for 24 hours (filter pump must be on during this time) or until the power has been turned off, whichever comes first. At the end of the super chlorinate time, be sure to put the switch back into the AUTO position. OFF: The OFF position prevents the Aqua Rite from energizing the electrolytic cell. In this position there is no chlorine generation. NOTE: To service any of the pool equipment or the Aqua Rite, turn the power off at the circuit breaker. Indicator LED's POWER When illuminated, the Aqua Rite has input power. GENERATING This LED is on steady during normal operation. When flashing, the pool water is too hot or cold to operate. SUPER CHLORINATE Illuminates during super-chlorination. See description above. REMOTELY CONTROLLED When illuminated, indicates that a remote pool automation control (Hayward/Goldline Pro Logic, Pentair Intellitouch, Polaris Eos, etc.) is controlling the Aqua Rite--the main switch and "Desired Output %" adjustment are inactive. When flashing, the Pro Logic, Intellitouch or Eos is in SERVICE or TIME-OUT mode and the Main Switch and "Desired Output %" adjustment are active. NO FLOW When illuminated, the flow switch has detected no water flowing and the Aqua Rite has stopped generating chlorine. A flashing LED indicates a 15-60 second time delay period. CHECK SALT When flashing, the salt level is low (below 2700 ppm) and Aqua Rite is generating at low efficiency. When illuminated steady, the salt level is too low and Aqua Rite has shut down. Before adding large quantities of salt, it is advisable to have your salt level professionally checked. HIGH SALT When illuminated, the salt level is too high and Aqua Rite has shut down. INSPECT CELL A flashing indicator signifies that either the cell efficiency is reduced or that it is time for regularly scheduled cell inspection. In either case, inspect cell and clean if necessary. When illuminated steady, cell efficiency is greatly reduced and the Aqua Rite has stopped producing chlorine. Inspect, clean or replace if necessary. 6
