Introduction
This quick start guide provides essential installation and startup instructions for the Zodiac Ei² iQ salt electrolysis system. For comprehensive details, users should consult the full online manual, accessible via a QR code scan (typically found on the product or documentation cover), and adhere to all safety warnings before beginning installation.
All assembly, electrical installation, and maintenance tasks should be performed by authorized, qualified technicians who have thoroughly read all provided installation and service instructions.
General Characteristics
The Zodiac Ei² iQ system is a salt electrolysis system designed to maintain pool water healthiness by producing free chlorine. It consists of two main components: an electrolysis cell and a control unit. The electrolysis cell contains titanium plates (electrodes) that, when an electric current passes through them and the salt solution, generate free chlorine. The system operates when the pool's filtration system (pump and filter) is running. The control unit includes safety devices and a micro-controller for managing operations. A key feature is the automatic electrode cleaning system, which prevents the buildup of incrustations.
Safety Warnings and Recommendations
Installation and handling of this equipment must only be performed by suitably qualified technicians. All applicable accident prevention standards and electrical installation regulations must be respected.
- Ensure electrical disconnection via a switch or circuit breaker compliant with IEC 60947-1 and IEC 60947-3 for omnipolar cut-off.
- The switch must be easily accessible and marked as the disconnection element.
- The equipment must be powered through a residual current device (RCD) not exceeding 30 mA and must be earthed.
- Installation must comply with IEC / HD 60364-7-702 and relevant national standards for swimming pools.
- The manufacturer is not responsible for issues arising from unauthorized assembly, installation, or component manipulation.
- This appliance is not intended for use by persons with reduced physical, sensory, or mental capabilities, or lack of experience, unless supervised by a responsible person. Children should be supervised to ensure they do not play with the appliance.
- If the power cable is damaged, it must be replaced by the manufacturer, their service agent, or a similarly qualified technician.
- Do not attempt to modify the control unit for operation at different voltages.
- Ensure all electrical connectors are tightened properly to prevent overheating.
- Always disconnect the system from the power supply and ensure no water is flowing before installing or replacing any component. Use only genuine replacement parts.
- Install the equipment in a well-ventilated area, away from flammable materials, as it generates heat.
- Despite its IP rating, do not install in areas with a risk of flooding.
- The equipment is designed for permanent connection to the water supply; do not use a temporary hose.
- A mounting bracket is included; refer to installation instructions for use.
Initial Start-Up
- Ensure the filter is 100% clean and the pool water is free of copper, iron, and algae. Verify that any installed heating equipment is compatible with salt water.
- Balance the pool water to achieve more efficient treatment with lower free chlorine levels and extend electrode life by reducing limescale.
- Maintain the salt level at the recommended 5 g/L (5 kg/m³ or 0.5%), within the system's operating range of 3-8 g/L.
- Before starting the operating cycle, disconnect the control unit and run the filter pump for 24 hours to ensure complete salt dissolution.
- Start the saline electrolysis system, setting it to maintain free chlorine levels within the recommended range of 0.5-2 ppm.
Pool Water Balance
Maintain the following water parameters:
- Total alkalinity: 80-150 mg/L (ppm)
- pH: 7.2-7.6
- Free chlorine: 0.5-2 mg/L (ppm)
- Chlorine stabiliser: 25-30 mg/L (ppm). For pools exposed to strong sunshine or intensive use, maintaining 25-30 mg/L of stabiliser (isocyanuric acid) is advisable.
Refer to the full manual for detailed information on sensor installation/calibration (pH, ORP, g/L, temperature) and electrolysis cell/peristaltic pump maintenance.
Components and Installation
Components
The system includes the main Equipment (control unit), Electrolysis Cell, Temperature kit, Installation kit, and optional pH kit and ORP kit (available for Ei2 iQ pH EVO models). A Flow switch kit may also be included.
Wall-Mounting
The equipment should be installed upright on a rigid, dry, and well-ventilated surface. It is recommended to protect the equipment from weather and avoid creating corrosive atmospheres. Mounting typically involves screws such as 5x35 mm or 7x35 mm.
Electrolysis Cell Electrical Connections
The cell must be installed in a horizontal tube, ensuring water flows through it at an angle or inclination not exceeding 30°. Note the direction of water circulation. The installation involves fitting the cell into the pipe using an adapter (e.g., DN50 mm), securing it with a clamping ring, and connecting the electrical supply cable according to color codes (e.g., BLACK WIRE, RED WIRE, BLUE WIRE (AUX), ORANGE WIRE (TEMP)).
Installation Diagram
The installation diagram illustrates the system's plumbing and electrical connections. It shows the main equipment, filter, electrolysis cell, pH sensor, ORP sensor, flow switch, and pH pump connected to the pool's water circuit and a 230 Vac power supply. This diagram represents a typical setup for an Ei2 iQ pH EVO model with all options, though layouts may vary by specific model.
Inside View and User Interface
Inside View
The internal view shows the control unit's layout, including the ON/OFF switch, connections for the Cell, 230 Vac supply, ORP sensor, pH sensor, pH pump (with fuse), Modbus communication, Flow sensor, and covers. It also indicates connections for Wi-Fi/BT and external ORP control.
Starting Sequence
The startup sequence involves powering on the unit. Users can activate/deactivate Wi-Fi/BT and pH/ORP drivers. The interface displays firmware version, IOT settings, and model information. A reset to factory defaults option is available.
User Interface
The main "Home" screen (Ei2 iQ pH EVO) displays key parameters: Electrolysis % (set point and current), Current pH (with set point), and Current mV (ORP) (with set point). Navigation is done via INFO, SET, and '+' buttons. Additional displays show Current g/L and Current temperature. The interface also indicates active alarms, such as PS (Pump Stop), and equipment polarity (Direct/Inverted).
Configuration Menu
The configuration menu is accessed by pressing the "INFO" button for 5 seconds. It allows adjustment of various settings, including:

Troubleshooting Common Problems
| Message | Solution |
|---|---|
| Flow alarm (FE / FS) | Indicates the cell is not fully flooded or there is no water flow. Check the pump, filter, and backwash valve; clean if necessary. |
| STOP CL alarm (CLE / CLI) | CLE: Stopped by an external controller. Check the controller and reading. If no external controller, disable CLE function. CLI: Stopped by ClmV or Clppm value. Check pool chlorine level with a photometer or test strip. Clean and calibrate ORP/ppm sensor if needed. |
| ORP (mV) - High alarm | Low or high alarms indicate readings outside safety limits. High ClmV limits are fixed (e.g., > 855 mV). Check pool chlorine, clean/calibrate ORP sensor. Address low free chlorine/high total chlorine with superchlorination. If ppm is high and mV is low, check cyanuric acid. High deviation during calibration (±60 mV) may indicate sensor or solution issues. |
| pH Low/High alarm | Low or high alarms indicate readings outside safety limits. Safety limits are fixed (e.g., pH < 6.5 or > 8.5 for Standard mode). Check pool pH with a photometer or test strip. Clean/calibrate pH sensor. Manually adjust pH if necessary (e.g., to 8.45 for Standard mode) for dosing to resume. High deviation during calibration (±1 pH unit) may indicate sensor or solution issues. |
| PUMP-STOP alarm | The dosing pump stops after a programmed time (default 60 min) without reaching the pH set point. Check pool pH, clean/calibrate pH sensor, check water alkalinity, and check acid levels in the container. |
| Cell alarm | Indicates the electrode is at the end of its life (passivated). Estimated electrode lifetime is 8,000-10,000 hours. Replace the electrode if necessary. |
| Low/High TEMPERATURE sensor alarm | Appears when temperature values are outside the user-set range (default OFF). Low temperatures can reduce production due to low conductivity. |
| Low/high g/L alarm | Appears when salt (g/L) values are outside the user-set range (default OFF). Incorrect salt levels affect output due to water conductivity. |
| Alarms E1-E5 |
