Installing a Redox Pool Controller: How to Do It?

Redox control allows for assessing pool water quality and measuring the disinfectant power of automatic treatment. It becomes essential when the pool is covered with a shelter or a tarp. Additionally, it saves time by reducing human intervention, manual checks, and adjustments, which are often approximate and not always done at the right time.

How to Install the Redox Controller?

The Redox controller is installed in the technical room during pool construction or renovation. It operates in conjunction with an automatic chlorine, bromine dispenser, or a saltwater chlorinator. It is unnecessary to install it if the treatment is manual. The Redox potential measurement is sensitive to pH variations, so a pH regulator is necessary.

Pre-installation Steps for the Redox Controller

To install the Redox controller yourself, solid knowledge in plumbing and electricity (particularly complying with NF-C 15 100 standards) is required.
Reading and following the installation manual and understanding the overall pool operation are essential. Professional intervention can be beneficial.
The technical room must be frost-free, without humidity or condensation, protected from water splashes, rain, and sun, with a temperature not exceeding 40°C (depending on devices).
Before any intervention in the technical room during renovation, the power supply is turned off, the pool filter valve is set to "Close," and the hydraulic circuit valves are closed.

Where to Place the Redox Controller?

The first step is to install the control box. It should be mounted on a solid, clean wall with minimal deformation. It must be close enough to the power supply or the pool's electrical panel, the automatic treatment system, and the Redox probe.
A mounting kit is often provided with the device.
The electrical circuit is protected by a differential, and the control box by a fuse or a suitable circuit breaker.

Step Two: Installing the Redox Probe

Generally, the Redox probe is installed after the filter, before the electrolysis cell or the automatic chlorine or bromine dispenser, and before the pH injection point if there is a regulator. A distance between the Redox measurement point and the pH injection point may be recommended.
A saddle clamp and probe holder, usually supplied with the device, are installed directly on the pool's return pipe.
If multiple probes are required for the pool's proper operation, installing an analysis chamber via a bypass, which houses the Redox, pH, and/or temperature probes, is beneficial. This avoids drilling the pipe in several places and limits potential leaks.
Then, remove the cap protecting the probe bulb, insert the probe vertically into its specific housing, probe holder, or analysis chamber without touching the tube. The bulb must be immersed in water.

Step Three: Connecting the Redox Controller

This part requires a lot of attention and precision.
Now, connect the Redox probe to the control box, link the control box to the automatic chlorine or bromine dispenser, or the saltwater chlorinator, and connect the Redox control box to the pool's electrical panel.
One solution, one advice: follow the installation manual instructions scrupulously!
The Redox setpoint can be adjusted following the programming protocol. The probe is factory calibrated; however, checking and correcting the calibration with a buffer solution at least once a year, at the end of winterizing, and mid-season is necessary.
Finally, turn on the power supply in the technical room, open the water circulation valves in the pool circuit.
Before starting the Redox controller, ensure the water is balanced, with a pH between 7.2 and 7.6, a stabilizer level ideally between 20 and 30 mg/l, and alkalinity below 100 mg/l, as these factors influence the accuracy of the Redox measurement.

The installation of the Redox controller is complete. The device will now adjust the disinfectant production according to the pool's actual needs, not at regular intervals. Enjoy swimming regardless of the weather conditions and pool usage.
