The AquaRite® – CUL Electrolytic Chlorine Generator is an automatic chlorine generation system designed for pool or spa sanitation. It operates by converting a low concentration of salt (sodium chloride) in the pool water into free chlorine, which then kills bacteria and algae. After killing bacteria, the chlorine reverts back to sodium chloride, creating a continuous recycling process that virtually eliminates the need to add sanitizing chemicals to the pool. Salt only needs to be added when water is replenished due to backwashing, draining, or splashing.
Function Description:
The device generates hypochlorous acid, which acts as the sanitizing agent. It is designed for residential pools and spas, with a maximum output of hypochlorous acid equivalent to 0.45 kg of chlorine per day. The system includes a FLO sensor that cuts off power to the cell if no water flow is detected, preventing the build-up of flammable gases. For proper operation, the AquaRite CUL Electrolytic Chlorine Generator must be wired to the same circuit as the filter pump, ensuring chlorine generation only occurs when the pump is providing flow.
Important Technical Specifications:
- Part No.: AQ-RITE-CUL
- Registration Number: 28325 (Pest Control Products Act)
- Maximum Water Volume: 95,000 Litres (25,000 Gallons)
- Electrical Ratings:
- Power: 110-130VAC, 2A, 50/60Hz or 220-250VAC, 1A, 50/60Hz.
- Wiring: Copper wire only, must conform to local and NEC/CEC codes.
- Ground Fault Protection: Connect only to a circuit protected by a class-A ground fault interrupter.
- Bonding: Requires an insulated or bare copper conductor not smaller than 8 AWG US / 6 AWG Canada to connect to the local common bonding grid.
- Enclosure: Suitable for indoor or outdoor mounting (raintight).
- Mounting Distance: Minimum of 2 meters (5 ft.) horizontal distance from the pool/spa.
- Plumbing: Designed for 51mm (2") PVC pipe; adapters (not included) can be used for 38mm (1 ½") plumbing. The flow switch requires at least a 25cm (12") straight pipe run before (upstream) it.
- Salt Level: Ideal range is 2.7-3.4 g/l (2700-3400 ppm), with 3.2 g/l (3200 ppm) being optimal.
- Chlorine Residuals: Minimum of 1 ppm for swimming pools, 3 ppm for spas.
- Maximum Spa Water Temperature: 40°C.
- Certifications: C-UL Listed 6D22, NSF Certified to ANSI/NSF Standard 50 Swimming Pool and Spa Chlorinator.
Usage Features:
- Main Switch (Ignored when Remotely Controlled):
- AUTO: Normal operation, chlorine production based on the "Desired Output %" dial setting for the entire filtering/pumping cycle.
- SUPER CHLORINATE: Produces chlorine at the maximum rate for 24 hours (or until power is turned off) to address high bather loads, cloudy water, or other purification needs. Overrides the "Desired Output %" dial.
- OFF: Turns off chlorine production. Power is controlled by the filter pump timer.
- Chlorine Level Dial ("Desired Output %" - Ignored when Remotely Controlled): Adjusts the amount of chlorine produced. Users should periodically check pool chlorine levels and adjust as needed.
- LCD Display: Shows salt level in ppm (parts per million). Can be switched to grams/liter and display temperature in Celsius/Fahrenheit.
- Indicator LEDs:
- POWER: Indicates input power.
- GENERATING: Steady when producing chlorine; flashing if water is too hot or cold to operate.
- SUPER CHLORINATE: Illuminates during super-chlorination.
- REMOTELY CONTROLLED: Illuminates when a remote pool automation control (e.g., Goldline Aqua Logic, Pentair Intellitouch, Polaris Eos) is controlling the unit; flashing if the automation control is in SERVICE or TIME-OUT mode.
- NO FLOW: Illuminates when no water flow is detected, halting chlorine generation; flashing indicates a 15-60 second time delay.
- CHECK SALT: Flashing if salt level is low (below 2700 ppm) and efficiency is reduced; steady if salt level is too low (below 2300 ppm) and generation is halted.
- HIGH SALT: Illuminates if salt level is too high, halting chlorine generation.
- INSPECT CELL: Flashing indicates reduced cell efficiency or scheduled inspection time; steady indicates greatly reduced efficiency and halted generation.
- Compatibility: Designed to operate with most pool automation controls (except Jandy AquaLink RS).
Maintenance Features:
- Cell Inspection: Recommended every 3 months or after cleaning the filter (approximately every 500 hours of operation). The "Inspect Cell" LED will flash as a reminder.
- Cell Cleaning:
- Visually inspect for scale formation or debris.
- Flush with a high-pressure garden hose.
- If deposits persist, use a plastic or wood tool to scrape them off (avoid metal tools).
- For severe cases, mild acid washing (4:1 water to muriatic acid solution) can be used. Ensure the wiring harness compartment is not submerged.
- Salt Level Management: Add salt directly to the pool (not the skimmer) and brush to speed dissolution. Run the filter pump for 24 hours to disperse salt evenly. To lower high salt levels, partially drain the pool and refill with fresh water.
- Water Chemistry Monitoring: Periodically test pool water for salt level, stabilizer (cyanuric acid), pH, calcium hardness, and total alkalinity to prevent corrosion or scaling.
- Winterizing: Drain all water from the pump, filter, and supply/return lines in areas with freezing temperatures to prevent damage to the cell and flow switch. The electronic control can withstand winter weather and does not need to be removed.
- Spring Start-up: Do not activate the unit until pool water chemistry has been brought to proper levels. If using new water, add metal remover and non-copper based algaecide.
- Troubleshooting Diagnostics: A "diagnostic" button allows sequential display of: pool temperature, cell voltage, cell current, desired output %, instant salinity, product name, and software revision level.
- Replacement Cells: Only use replacement cells specifically labeled for the AquaRite CUL Electrolytic Chlorine Generator, REGISTRATION NUMBER 28325, PEST CONTROL PRODUCTS ACT. The cell has a life expectancy of 10,000 hours under normal use.
