Gre SWGA100 Salt Chlorinator with pH Controller - Instruction Manual

1. Product Overview

The Gre SWGA100 Salt Chlorinator is an all-in-one device designed for automatic pool water disinfection. It generates chlorine from common salt through electrolysis, eliminating the need for storing and handling chemical products. This model is suitable for pools up to 100 m³ and includes an integrated pH controller and peristaltic pump for precise pH management.

Key features include:

• Automatic chlorine generation (21 grams per hour) for pools up to 100 m³.
• Integrated pH controller and peristaltic pump.
• Connectivity via the Fluidra App for remote management and control.
• Five operating modes: Standard, Boost, Cover, Slave, and Biopool for optimized function and energy saving.
• Intuitive interface displaying important parameters like chlorine level and water temperature.

2. Safety Information

Please read all safety instructions carefully before installation and operation. Failure to follow these instructions may result in injury or damage to the equipment.

• Ensure the device is securely and stably inserted into the pool.
• Avoid touching the device when it is powered on.
• Keep the device away from children and pets.
• Always disconnect power before performing any maintenance or adjustments.
• Consult a specialized technician if you have any doubts regarding installation or operation.

3. Setup and Installation

The installation and configuration of the Gre SWGA100 are designed to be quick and straightforward. Follow these steps for proper setup:

1. Prepare the Pool: Fill the pool with water. Add common salt until the concentration reaches between 3000-5000 ppm (parts per million).
2. Unpack Components: Carefully remove the chlorinator unit and all accessories from the packaging.
3. Attach Connectors: The device comes with 1-1/2" input and output connectors. Ensure these are securely attached to the chlorinator cell.
4. Connect to Filtration System: Integrate the salt chlorinator into your pool's filtration system. Ensure the water flow direction is correct through the chlorinator cell. The device should be installed after the filter and before the return to the pool.
5. Power Connection: Connect the power cable to the device and then to a suitable electrical outlet (AC110-220V, 50-60Hz). The screen will illuminate, indicating it's ready for configuration.
6. Secure Placement: Insert the device securely and stably into the pool or ensure it is properly mounted in the technical room.

4. Operating Instructions

Once installed and powered on, the Gre SWGA100 is ready for operation. The intuitive interface allows for easy monitoring and adjustment.

1. Initial Start-up: Turn on the device. Allow it to operate until the chlorine level in the pool is between 1.0 and 3.0 ppm.
2. pH Monitoring: Regularly monitor the water's pH level and maintain it between 7.2 and 7.6. The integrated pH controller will assist in this process.
3. Operating Modes: The device offers five distinct modes to suit various water conditions and pool needs:
   • Standard: Regular operation for consistent chlorine production.
   • Boost: Increases chlorine production for periods of heavy use or high organic load.
   • Cover: Adjusts operation when the pool is covered, reducing chlorine output.
   • Slave: Allows the device to be controlled by an external system.
   • Biopool: Specific mode for optimized biological water treatment.
4. Remote Control (Fluidra App): Utilize the Fluidra App to manage and control the electrolysis process remotely, ensuring clean and crystal-clear water from anywhere.

5. Maintenance

Regular maintenance ensures the longevity and optimal performance of your salt chlorinator. The Gre SWGA100 is designed for ease of maintenance.

• Self-Cleaning Function: The device features a self-cleaning function to prevent mineral buildup on the electrolysis cell. Refer to the device's interface or the Fluidra App for details on activating and scheduling this function.
• Cell Inspection: Periodically inspect the electrolysis cell for any signs of excessive scaling or damage. Clean the cell manually if necessary, following the instructions in the full user manual.
• Water Chemistry: Continue to monitor salt levels and pH regularly. While the device automates chlorine production and pH control, occasional checks are recommended to ensure optimal water balance.
• Winterization: During off-season or prolonged periods of non-use, follow the winterization procedures outlined in the comprehensive user manual to protect the device from freezing temperatures and ensure proper storage.

6. Troubleshooting

The Gre SWGA100 is equipped with an automatic fault alarm system to indicate operational issues. When an error code appears on the display, consult the full user manual for specific troubleshooting steps related to that code.

Common issues and general advice:

• Low Chlorine Production: Check salt levels in the pool. Ensure the electrolysis cell is clean and free of scale. Verify the operating mode is appropriate for current conditions.
• pH Imbalance: Check the pH probe for cleanliness and calibration. Ensure the peristaltic pump is functioning correctly and the pH correction fluid reservoir is not empty.
• No Power/Display Off: Check the power connection and the electrical outlet. Ensure no circuit breakers have tripped.
• Flow Issues: Ensure the pool pump is running and there is adequate water flow through the chlorinator cell. Check for blockages in the plumbing.
