4. Opsætning og installation

Proper installation is crucial for the optimal performance of your pH regulator. It is recommended to install this unit alongside a salt chlorinator, as salt electrolysis tends to increase water pH.

4.1 Montering af controlleren

1. Choose a suitable location near your pool's filtration system, ensuring it is protected from direct weather exposure.
2. Use the provided mounting screws to securely attach the pH controller unit to a vertical surface.

4.2 Connecting the Tubing and Valves

1. Connect the PVC aspiration tube to the inlet port of the peristaltic pump on the controller.
2. Attach the foot valve to the other end of the PVC aspiration tube and place it into your pH reducer chemical container.
3. Connect the PEHD injection tube to the outlet port of the peristaltic pump.
4. Install the FPM injection valve into your pool's return line (after the filter and heater, if applicable) using the saddle clamp. Ensure the valve is positioned to inject the pH reducer into the main water flow.
5. Connect the PEHD injection tube to the injection valve.

4.3 Connecting the pH Probe

1. Carefully uncap the pH probe.
2. Connect the pH probe cable to the designated port on the controller unit.
3. Install the pH probe into the pool's circulation system, typically in a bypass line or a dedicated probe holder, ensuring it is constantly immersed in flowing water.

4.4 Calibrating the pH Probe

Accurate calibration is essential for precise pH readings.

1. Prepare the calibration solutions (pH 7.02 and pH 4.00).
2. Follow the specific calibration procedure outlined in the controller's display menu (refer to the "CAL ENTER" button on the unit). Typically, this involves rinsing the probe, immersing it in pH 7.02 solution, confirming the reading, then rinsing and immersing in pH 4.00 solution and confirming.
3. Once calibrated, the probe is ready for use.

5. Betjeningsvejledning

The Gre CPH14 automatically regulates pH levels. Once installed and calibrated, minimal user intervention is required.

1. Tænd: Connect the unit to a suitable power outlet. The display will illuminate.
2. Set Target pH: Use the controller's buttons (e.g., "ESC", "SET") to navigate the menu and set your desired pH target value (typically between 7.2 and 7.6 for swimming pools).
3. Automatisk drift: The controller will continuously monitor the pool's pH level via the probe. If the pH deviates from the set target, the peristaltic pump will automatically inject the pH reducer until the desired level is restored.
4. Overvågning: Periodically check the display to ensure the pH is within the desired range.

6. Vedligeholdelse

Regular maintenance ensures the longevity and accuracy of your pH regulator.

• pH Probe Cleaning: Clean the pH probe regularly (e.g., monthly or as needed) to remove any buildup that may affect its accuracy. Use a soft cloth and a mild cleaning solution specifically designed for pH probes.
• pH Probe Re-calibration: Re-calibrate the pH probe periodically (e.g., every 3-6 months, or if readings appear inaccurate) using fresh calibration solutions.
• Check Chemical Levels: Ensure there is always sufficient pH reducer chemical in the container connected to the aspiration tube.
• Inspicer slange: Periodically check the PVC and PEHD tubing for any signs of wear, cracks, or blockages. Replace if necessary.
• Vinterisering: During winter months or extended periods of non-use, disconnect the unit, drain all tubing, and store the controller and probe in a dry, frost-free environment.
