ASTRALPOOL SMART NEXT Chlorine Generator User Manual

1. Introduction

The ASTRALPOOL SMART NEXT 21 g/h is an advanced electronic chlorine generator designed for the automatic disinfection of swimming pool water up to 80 m³. This system produces chlorine from salt dissolved in the pool water, providing a continuous and effective sanitization method. It aims to simplify pool maintenance by reducing the need for manual chlorine dosing and improving water quality.

This manual provides essential information for the safe and efficient installation, operation, and maintenance of your ASTRALPOOL SMART NEXT system. Please read it thoroughly before attempting any installation or operation.

The control unit features a digital display showing water parameters like pH and temperature, along with various control buttons. The electrolytic cell is a cylindrical transparent component with internal electrodes, designed for inline installation in the pool's plumbing system.

2. Safety Information

Always observe the following safety precautions to prevent injury and damage to the equipment:

• Electrical Safety: Ensure the power supply is disconnected before performing any installation, maintenance, or troubleshooting. All electrical connections must be made by a qualified electrician and comply with local electrical codes.
• Chemical Handling: Although the system generates chlorine, proper handling of pool chemicals (e.g., pH adjusters, salt) is still required. Always wear appropriate personal protective equipment (PPE) such as gloves and eye protection.
• Water Quality: Maintain proper water balance (pH, alkalinity, calcium hardness) as recommended for your pool. Incorrect water chemistry can damage the electrolytic cell and other pool equipment.
• Children and Pets: Keep the unit and all pool chemicals out of reach of children and pets.
• Ventilation: Ensure adequate ventilation in the area where the unit is installed, especially if other pool chemicals are stored nearby.

3. Package Contents

Verify that all components are present and undamaged upon unpacking:

• ASTRALPOOL SMART NEXT Control Unit
• Electrolytic Cell (Chlorine Generator Cell)
• Flow Switch (if included with model)
• pH Probe (if included with model)
• Temperature Sensor (if included with model)
• Mounting Hardware
• User Manual (this document)

If any items are missing or damaged, contact your dealer immediately.

4. Setup and Installation

4.1 Pre-Installation Checks

• Ensure the pool volume does not exceed 80 m³ for optimal performance.
• Verify the pool's plumbing system is compatible with the cell's connections.
• Confirm the electrical supply matches the unit's requirements (refer to specifications).
• Ensure adequate space for mounting the control unit and cell, allowing for ventilation and future maintenance.

4.2 Mounting the Control Unit

Select a dry, well-ventilated location, protected from direct sunlight and rain. Mount the control unit vertically using the provided mounting hardware. Ensure it is easily accessible for operation and display viewing.

4.3 Plumbing the Electrolytic Cell

The electrolytic cell must be installed in the pool's return line, after the filter and heater (if applicable), and before any chemical feeders. Ensure the flow direction arrow on the cell matches the water flow. Use appropriate PVC fittings and primer/cement for a watertight seal. Allow sufficient curing time before starting the pump.

4.4 Electrical Connections

All electrical connections must be performed by a qualified electrician. Connect the control unit to a dedicated, properly grounded electrical circuit protected by a Ground Fault Circuit Interrupter (GFCI) or Residual Current Device (RCD). Connect the electrolytic cell and any sensors (pH, temperature, flow) to the designated terminals on the control unit as per the wiring diagram in the full technical manual.

5. Operating Instructions

5.1 Initial Startup

1. Add Salt: Ensure the pool water has the correct salt concentration (typically 3,000-4,000 ppm, refer to specifications for exact range). Allow salt to dissolve completely before starting the system.
2. Balance Water: Adjust pH, alkalinity, and calcium hardness to recommended levels.
3. Power On: Turn on the power supply to the ASTRALPOOL SMART NEXT control unit.
4. Pump On: Start the pool circulation pump. Ensure water is flowing through the electrolytic cell.
5. System Initialization: The unit will perform a self-check. Follow any on-screen prompts for initial setup, such as language selection or date/time.

5.2 Control Panel Overview

Figure 2: Close-up view of the ASTRALPOOL SMART NEXT control unit's digital display. The screen shows numerical readings for pH (e.g., 7.31) and temperature (e.g., 28.3°C), along with a circular graphic indicating chlorine production levels. Below the main readings are icons and indicators for various functions and statuses, including menu navigation, information, calibration, and alarm indicators.

The control panel features a digital display and several buttons for navigation and settings. The display typically shows:

• Current Chlorine Output: Indicated by a percentage or graphic.
• Water Parameters: pH, ORP (Redox potential), Temperature (if sensors are connected).
• System Status: Flow, cell status, error codes.

Refer to the detailed technical manual for specific button functions and menu navigation.

5.3 Adjusting Chlorine Production

The chlorine output can be adjusted to meet your pool's sanitization needs. Access the settings menu on the control unit and modify the production percentage. Start with a moderate setting and adjust based on daily chlorine residual tests (e.g., 1-3 ppm free chlorine).

5.4 Super Chlorination (Boost Mode)

For periods of heavy bather load, rain, or algae presence, the system may offer a "Boost" or "Super Chlorination" mode. This temporarily increases chlorine production to maximum levels. Consult your manual for activation and duration settings.

6. Maintenance

6.1 Electrolytic Cell Cleaning

Over time, calcium and other mineral deposits can accumulate on the cell plates, reducing efficiency. The system may indicate when cleaning is required. To clean the cell:

1. Disconnect Power: Turn off the power to the chlorine generator and pool pump.
2. Remove Cell: Disconnect the cell from the plumbing and electrical connections.
3. Inspect: Visually inspect the plates for scaling.
4. Acid Wash: Prepare a mild acid solution (e.g., 1 part muriatic acid to 4 parts water, always add acid to water). Submerge the cell plates in the solution, ensuring the electrical connections remain dry. Allow to soak until deposits dissolve (usually 10-15 minutes). Do not scrub with abrasive materials.
5. Rinse and Reinstall: Rinse the cell thoroughly with fresh water and reinstall it, ensuring all connections are secure.

Perform this cleaning as needed, typically every 3-6 months, depending on water hardness.

6.2 Sensor Calibration and Cleaning

If your system includes pH or ORP sensors, they require periodic calibration and cleaning to ensure accurate readings. Refer to the detailed manual for specific calibration procedures using buffer solutions. Clean sensors gently with a soft brush and mild detergent, rinsing thoroughly.

6.3 Winterization

In regions subject to freezing temperatures, the ASTRALPOOL SMART NEXT system must be properly winterized. This typically involves:

• Disconnecting power.
• Draining all water from the electrolytic cell and associated plumbing.
• Removing the electrolytic cell and sensors, cleaning them, and storing them in a dry, frost-free location.
• Protecting the control unit from extreme temperatures and moisture.

7. Troubleshooting

This section addresses common issues. For more complex problems, contact technical support.
