The Jandy AquaPure Electronic Chlorine Generator is a device designed to automate pool sanitation by producing chlorine from salt dissolved in the pool water. It uses electrolysis to convert sodium chloride (salt) into hypochlorite (liquid chlorine), which then sanitizes the pool by oxidizing organic material and killing algae. After sanitizing, the hypochlorite reverts to salt, allowing the process to repeat. The system comprises a control center, an electrolytic cell, and a flow/temp/salinity sensor.
Function Description:
The AquaPure system continuously generates chlorine, reducing the need for manual addition of chlorine. It is designed to maintain a consistent chlorine level in the pool, improving water quality and reducing the effort involved in pool maintenance. The control center manages the chlorine production, while the electrolytic cell performs the electrolysis. The flow/temp/salinity sensor monitors critical parameters like water flow, temperature, and salt levels to ensure safe and efficient operation. The system can be integrated with a Jandy AquaLink RS control system for enhanced automation and remote control.

Pool Sizing (Residential Pools):
- PURE700: One (1) unit per 57 m³ (up to 15,000 gal) pool (year-round use); One (1) unit per 66 m³ (up to 17,500 gal) pool (winterized).
- PURE1400: One (1) unit per 114 m³ (up to 30,000 gal) pool (year-round use); One (1) unit per 132 m³ (up to 35,000 gal) pool (winterized).
Optimum Pool Water Conditions:
- Free Chlorine: 1.0 - 3.0 PPM (Above 3.0 PPM may cause corrosion of pool metals).
- Combined Chlorine (Chloramines): None (Super Chlorinate to remove all Chloramines).
- pH: 7.2 - 7.8 (Use MURIATIC ACID to lower pH and Soda Ash to raise pH).
- Chlorine Stabilizer (Cyanuric Acid): 50 - 75 PPM.
- Total Alkalinity: 80 - 120 PPM.
- Calcium Hardness: 150 - 400 PPM.
- Metals (Copper, Iron, Manganese): None.
- Nitrates: None.
- Salt (NaCl sodium chloride): Recommended range is 3.0 - 3.5 gpl (grams per liter) or 3000 - 3500 PPM. The AquaPure display indicates the salinity level of the pool water.
Usage Features:
- Front Panel Controls: The control center features a display and buttons for adjusting chlorine production rate, checking salinity, and viewing pool temperature.
- Chlorine Production Rate Adjustment: Arrow buttons (A and B) allow for increasing or decreasing chlorine production in 1% increments.
- Salinity Check: Button C displays the salinity of the water in gpl.
- Boost Mode: Button D, when pressed for 10 seconds, activates the Boost mode, which sets chlorine production to maximum (100%) for 24 hours. This is useful for shocking the pool.
- Temperature Display: Button D also displays the pool water temperature in Fahrenheit or Celsius.
- Beep Control: The system volume can be adjusted, and the display can be toggled between different screens.
- AquaLink RS Integration: The AquaPure system can be connected to a Jandy AquaLink RS control system, allowing for remote control and advanced automation features. This integration enables the AquaLink RS to control chlorine production and monitor system status.
- Winter Mode: The AquaPure can operate in winter conditions, but specific recommendations apply for colder temperatures to prevent over-chlorination. Below 51 degrees Fahrenheit, chlorine production should be limited or turned off.
- Self-Cleaning Cell: The electrolytic cell features an automatic cleaning cycle (Cell Reversing) to prevent scale buildup. The frequency of this cycle can be adjusted.
- Safety Features: The system includes warnings for electrical shock, fire, personal injury, and death. It requires installation by a qualified service professional and proper grounding. A ground fault circuit-interrupter (GFCI) is mandatory for the power supply.
Maintenance Features:
- Daily Maintenance: Check chlorine level using a reliable test kit. Maintain ideal range of 1-3 PPM.
- Weekly Maintenance: Test pH level and adjust to 7.2-7.8.
- Monthly Maintenance: Test salt level using a test kit or by observing the AquaPure control center display. Maintain 3.0-3.5 gpl. Take pool water sample to Pool Professional once per month. Test total alkalinity, stabilizer (cyanuric acid), calcium hardness, and metals.
- Electrolytic Cell Cleaning: The cell has an automatic cleaning feature (Cell Reversing). If manual cleaning is required, it involves removing the cell and soaking it in a mild acid solution (e.g., muriatic acid) to remove scale and debris. This should be done by a qualified service professional.
- Flow/Temp/Salinity Sensor Cleaning: The sensor should be cleaned periodically to ensure accurate readings. This involves removing the sensor and cleaning any debris or buildup.
- Winterizing: Proper winterization procedures are necessary to protect the system from freezing temperatures and ensure longevity. This may involve draining water from the cell and sensor, and storing them in a protected area.
- Troubleshooting: The manual provides a comprehensive troubleshooting guide with common problems, possible causes, and corrective actions, including service codes and additional letter codes displayed on the control center.
- Replacement Kits: Exploded views and part lists are provided for the control center, electrolytic cell, and flow sensor to facilitate ordering replacement parts.
