4. Setup and Installation
Installation of the BAYROL Salt Relax Pro should be performed by a certified technician. The following steps provide a general overview:
- Mounting: Securely mount the control unit in a dry, well-ventilated area, away from direct sunlight and corrosive chemicals.
- Plumbing: Install the electrolytic cell in the pool's return line after the filter and heater. Ensure proper water flow through the cell.
- Electrical Connection: Connect the control unit to a dedicated power supply, ensuring it is protected by a Residual Current Device (RCD).
- Sensor Connection: Connect the temperature sensor, and optional pH and Redox sensors, to the designated ports on the control unit.
- Salt Addition: Add the required amount of salt to the pool water to achieve a concentration of 1.5 g/l. Allow the salt to dissolve completely before starting the system.
- Initial Power-Up: Power on the unit and follow the on-screen prompts for initial configuration, including language selection and pool volume.
Refer to the detailed installation guide provided with the product for specific wiring diagrams and plumbing instructions.
5. Operating Instructions
5.1. Basic Operation
The Salt Relax Pro features an intuitive color screen and simple menu navigation.
- Main Screen: Displays current chlorine production percentage, water temperature (if sensor connected), and system status.
- Navigation Buttons: Use the UP/DOWN arrows to navigate through menus and adjust settings. The OK button confirms selections.
- Production Adjustment: Adjust the chlorine production level (e.g., 30% shown in image) based on your pool's needs and water test results.
5.2. Boost Function
The "Boost" function allows for a temporary increase in chlorine production, acting as a shock treatment for your pool water. This is useful after heavy use, rain, or when algae growth is observed.
- Activating Boost: Navigate to the "Boost" option in the menu and activate it. The system will produce a higher quantity of chlorine for a set period.
- Duration: The duration of the Boost cycle is typically pre-set or configurable within the menu.
- Monitoring: Monitor chlorine levels after a Boost cycle to ensure they return to safe operating ranges.
5.3. pH and Redox Module Integration (Optional)
If equipped with optional pH and Redox modules, the system can automatically regulate pH levels and optimize disinfectant production.
- Automatic pH Regulation: The pH module will automatically dose pH correction chemicals to maintain optimal pH levels.
- Redox Control: The Redox module ensures the appropriate level of disinfectant production based on the water's oxidation-reduction potential.
- Calibration: Periodically calibrate the pH and Redox sensors according to the instructions provided with the respective modules.
6. Maintenance
6.1. Self-Cleaning Electrolytic Cell
The Salt Relax Pro features a self-cleaning electrolytic cell through polarity reversal, which minimizes scale buildup and ensures consistent disinfection.
- Regular Inspection: Periodically inspect the cell for any excessive scale buildup that the self-cleaning function might not fully remove.
- Manual Cleaning (if necessary): If significant scale is present, carefully remove the cell and clean it using a diluted acid solution specifically designed for chlorinator cell cleaning. Follow the cleaning product's instructions.
- Rinse Thoroughly: After cleaning, rinse the cell thoroughly with fresh water before reinstallation.
6.2. General Care
- Keep Unit Clean: Wipe the exterior of the control unit with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Check Connections: Periodically check all electrical and plumbing connections for tightness and signs of wear.
- Water Chemistry: Regularly test your pool water for salt levels, pH, and chlorine to ensure optimal system performance and water balance. Maintain salt levels at approximately 1.5 g/l.
7. Troubleshooting
This section addresses common issues you might encounter with your Salt Relax Pro.
| Problem | Possible Cause | Solution |
|---|---|---|
| No Chlorine Production | Low salt level, dirty cell, no power, low water flow. | Check salt level and add salt if necessary. Inspect and clean the electrolytic cell. Verify power supply to the unit. Ensure pool pump is running and water flow is adequate. |
| Error Message on Screen | Sensor malfunction, system fault, low/high salt. | Note the error code and consult the detailed manual for specific troubleshooting steps. Check sensor connections. Verify salt levels. |
| Inconsistent Chlorine Levels | Incorrect production setting, fluctuating water chemistry, cell scaling. | Adjust production setting. Regularly test and balance pool water chemistry (pH, alkalinity, stabilizer). Clean the electrolytic cell. |
If you encounter issues not listed here or if solutions do not resolve the problem, contact BAYROL customer support or a qualified pool technician.
