1. Introducció
This manual provides essential information for the installation, operation, and maintenance of your Astralpool Micro RX Automatic Chlorine Regulator. Please read this manual thoroughly before using the device to ensure safe and efficient operation.
The Astralpool Micro RX is an electromagnetic regulator designed for automatic control and regulation of chlorine (Redox) levels in swimming pools. It precisely monitors the water's Redox potential and injects chemical products as needed using a peristaltic pump. This system ensures optimal water quality, reduces manual maintenance, and enhances pool safety.
2. Informació de seguretat

4. Configuració i instal·lació
Proper installation is crucial for the correct functioning of the Micro RX regulator. Follow these steps carefully:
- Muntatge de la unitat: Use the provided wall mounting kit to securely attach the Micro RX unit to a vertical surface near your pool's filtration system. Ensure it is protected from direct sunlight and excessive moisture.
- Installing the Probe: Install the Rx probe into the probe holder. The probe holder should be installed in the pool's circulation line, typically after the filter and heater, but before any chemical injection points. Ensure the probe is always submerged in water when the system is running.
- Tubs de connexió:
- Connect the suction tube from the chemical container (e.g., liquid chlorine) to the suction strainer, then to the inlet of the peristaltic pump.
- Connect the discharge tube from the pump outlet to the injection valve. The injection valve should be installed into the pool's return line using the provided support collars.
- Connexió elèctrica: Connect the Micro RX unit to a 230V power supply. Ensure the connection is secure and protected from water.
- Calibració inicial: Before first use, the Rx probe must be calibrated using the provided calibration solutions. Refer to the "Operating" section for detailed calibration instructions.
5. Instruccions de funcionament
The Micro RX regulator is designed for user-friendly operation. Follow these steps to set up and maintain your desired chlorine (Redox) levels.
5.1 Power On and Display
Once connected to power, the LED display will illuminate, showing the current Redox potential in mV. The unit will automatically begin monitoring the water.
5.2 Calibració
Regular calibration of the Rx probe is essential for accurate readings and effective regulation. Perform calibration:
- Premeu el botó CAL button. The display will enter calibration mode.
- Follow the on-screen prompts (if any, or refer to specific model instructions for calibration solution values).
- Immerse the probe in the first calibration solution. Wait for the reading to stabilize, then confirm.
- Esbandiu la sonda amb aigua destil·lada.
- Immerse the probe in the second calibration solution. Wait for the reading to stabilize, then confirm.
- The unit will save the calibration settings and return to normal operation.
5.3 Setting the Setpoint
The setpoint is the desired Redox value you want to maintain in your pool water.
- Premeu el botó SET button. The display will show the current setpoint value.
- Utilitza el CAL i SET buttons (or dedicated up/down buttons if available) to adjust the setpoint to your desired value (e.g., 650-750 mV for typical chlorine levels).
- Premeu SET again to confirm and save the new setpoint.
The Micro RX will now automatically inject chlorine when the measured Redox level falls below the setpoint, and stop when the setpoint is reached or exceeded.
6. Manteniment
Regular maintenance ensures the longevity and accuracy of your Astralpool Micro RX regulator.
- Neteja de la sonda: Periodically clean the Rx probe to remove any deposits that may affect its accuracy. Use a soft brush and a mild cleaning solution specifically designed for probes, or distilled water.
- Calibració de la sonda: Recalibrate the probe regularly (e.g., monthly or as recommended by pool professionals) to ensure precise readings.
- Electrode Wear Monitoring: The unit features an electrode wear monitoring function. If an alert is displayed, inspect or replace the Rx probe as necessary.
- Peristaltic Tube Inspection: Inspect the peristaltic pump tubes for signs of wear, cracks, or blockages. Replace them if necessary to maintain proper dosing.
- Chemical Levels: Ensure the chemical container connected to the suction tube always has sufficient product. The unit has a safety feature for empty dosing.
- Neteja general: Keep the exterior of the unit clean and free from dust and chemical spills.
