Automatic Regulation Just Regul - DUO pH+Rx

• Automatic self-cleaning regulation JustRegul.
• Automatic measurement and dosing JustRegul by the French manufacturer Pool-technologie is intended for private pools.
• JustRegul measures water Redox potential and pH using an ORP probe.

JustRegul station DUO pH+Rx automatically measures and monitors the water value and ORP. The device automatically doses pH and controls the sanitization unit according to the redox potential of the pool water.

This device controls the sanitization unit thanks to measuring the oxidation-reduction potential (ORP). To maintain optimal water quality, the redox method works with a reference space and compares it to the set value. If regular measurements reveal a deficiency or excess of chlorine (each pool water is different), recalibrate the redox according to the instructions in the manual to obtain the ideal value.

Contents of the package:
1x Control unit with pH pump
2x 50 mm Ø ½’’ fittings
1x pH probe
2x calibration solutions pH7 and 10
5 m semi-rigid tubing
1x injector Ø ½ ’’
1x probe holder Ø ½’’
1x suction basket


During the initial installation of the device, or at the start of each new season, check and perform the following items:

WATER STATE	The water should be clean, free of algae and other impurities.
pH VALUE 7.0 < pH < 7.4	Before starting the device, manually adjust the pH to the range 7.0 – 7.4.
Stabilizer value < 20 ppm	For optimal operation of the redox probe, it is recommended to have a stabilizer (iso-cyanuric acids) lower than 20 parts per million (mg / l).
Free CL value > 0,5 ppm	The water should already have chlorine above 0.5 ppm. Use chlorine shock.
Temperature > 15°C	The pool water temperature must not be below 15°C.
Hardness	Water hardness should be within moderate ranges (250-500ppm).

In case of winterizing the pool (draining and/or stopping filtration), perform the following operations:

• Remove pH and redox probes from the pipes (if installed).
• Store the probes in a container of water so that the probes are always submerged and cannot dry out or freeze.
• Rinse the flexible tubing of the peristaltic pump with clean water. Store the dosing liquid container in a frost-free place and use the "MA" function from the pH control menu (see § 4.2).
• After bringing the system back into service at the start of the season, remember to recalibrate.

More information regarding installation, parameter settings, usage, maintenance, etc. can be found in the manual, which is available in the Download section.
