- Bomba dosificadora: Delivers pH correction solution as needed to maintain desired levels.
This system is recommended for both above-ground and in-ground pools up to 60 m³.
Components:
- Control Unit with integrated pH controller and dosing pump.
- Electrolysis Cell (transparent housing with electrodes).
- pH Probe.
- Flow Sensor.
- Piping and connection accessories.
4. Instruccions de configuració
Careful installation is crucial for the proper functioning of your Gre SCGPHP60 system. Follow these steps for a successful setup:
4.1. System Assembly and Plumbing
- Preparació de les canonades: Cut and glue the PVC pipes and fittings to create the bypass system as shown in the diagram. Ensure all connections are secure and watertight.
- Install Saddle Clamps: Drill holes in the main pipe for the pH probe and flow sensor. Attach the saddle clamps, ensuring the rubber gaskets are correctly seated to prevent leaks. Secure them with bolts and nuts.
- Install pH Probe and Flow Sensor: Carefully insert the pH probe and flow sensor into their respective saddle clamps. Tighten the connections to ensure they are firmly in place.
- Connect Dosing Pump Tubes: Attach the clear dosing tubes to the pH dosing pump on the control unit and to the injection point on the plumbing. Ensure the tubes are cut to the appropriate length and secured with the provided fittings.
- Connect Electrolysis Cell: Integrate the electrolysis cell into the bypass plumbing. Ensure the flow direction matches the arrows on the cell.

4.2. Connexions elèctriques
- Unitat de control de muntatge: Securely mount the blue control unit in a dry, protected area, preferably within a pool equipment shed.
- Connectar l'alimentació: Connect the main power cable to a suitable electrical outlet.
- Connect Cell Cables: Attach the cables from the electrolysis cell to the designated terminals on the control unit. Ensure correct polarity (red to red, yellow to yellow, etc.) and tighten the nuts securely.
- Connect pH Probe and Flow Sensor Cables: Plug the cables from the pH probe and flow sensor into their respective ports on the control unit.
- Connect Dosing Pump Power: Ensure the dosing pump is correctly connected to the control unit.

4.3. Initial Pool Preparation
- Add Salt: Ensure the pool water has a salt concentration of 4 g/l (grams per liter). This is crucial for the electrolysis process. Maintain a range of 3.2 g/l to 4 g/l for optimal performance.
- Assegurar el flux d'aigua: The system requires a minimum water flow rate of 3 m³/h to operate correctly. Ensure your pool pump is capable of providing this flow.

5. Instruccions de funcionament
Once installed, the Gre SCGPHP60 system is designed for automated operation. Here are the key aspects of its functionality:
5.1. Engegada i configuració inicial
- Encès: Turn on the main power to the system. The control unit will initiate a self-check.
- Producció de clor: The system will begin producing chlorine via salt electrolysis. The production rate can typically be adjusted via the control panel to suit your pool's needs.
- pH Monitoring: The pH controller will continuously monitor the pool's pH level. The current pH value will be displayed on the control unit.
- pH Dosing: If the pH deviates from the set point, the dosing pump will automatically inject pH correction solution (acid or base, depending on your setup and pool needs) to restore balance.
5.2. Funcions del tauler de control
- Power Selector (ON/OFF): Activates or deactivates the system.
- SALT Indicator: Illuminates to indicate the salt level in the pool. Refer to the specific salt level requirements in the setup section.
- pH Display: Shows the current pH value of the pool water.
- Botó SET: Used to enter the settings menu for adjusting parameters like desired pH level or chlorine production intensity.
- Botó CAL: Initiates the calibration process for the pH probe.
Refer to the detailed instructions in the full product manual for specific parameter adjustments and calibration procedures.
6. Manteniment
Regular maintenance ensures the longevity and efficiency of your Gre SCGPHP60 system.
6.1. Electrolysis Cell Cleaning
The electrolysis cell may accumulate scale over time, especially in hard water areas. Regular inspection and cleaning are necessary.
- Freqüència: Inspect the cell monthly or as recommended by the system's indicators.
- Procediment: Disconnect power. Remove the cell from the plumbing. Clean the electrodes using a diluted acid solution (e.g., muriatic acid) or a specialized cell cleaning product, following the manufacturer's instructions. Rinse thoroughly with clean water before reinstallation.

6.2. pH Probe Calibration
The pH probe requires periodic calibration to ensure accurate readings.
- Freqüència: Calibrate the pH probe at the beginning of each swimming season and periodically throughout, or if readings appear inaccurate.
- Procediment: Use certified pH calibration solutions (e.g., pH 7.0 and pH 4.0 or 10.0). Follow the calibration steps outlined in the control unit's menu using the CAL button.
