What Is ORP?

ORP (Oxidation-Reduction Potential, or Redox) is measured in millivolts (mV) and indicates the sanitizing power of your water. The more active disinfectant there is in the water, the higher the ORP value.

PoolOne-ORP measures this value continuously. When it drops below the set point, the pump doses disinfectant into the system and stops once the set point is reached. The right ORP value depends on the pool type and disinfectant used, so please consult our team before setting it.

Step 1
Measure ORP
The probe reads the water flowing past continuously.
Step 2
Compare with set point
The unit checks whether the value is below the set point.
Step 3
Dose disinfectant
The peristaltic pump doses into the line and stops at the set point.

Installation Notes
Before You Install
1
Install the ORP probe and chemical injection point at the positions specified in the manual (see the manual image below).
2
When used with a salt chlorinator, connect the electrical system to an earth (ground) point to eliminate stray electrical current.
3
Choose a disinfectant suited to your pool and tubing material. Consult our team before changing chemicals.

Powered by 220 - 240 Vac. Installation by a qualified technician is recommended. Make sure line pressure does not exceed the pump's maximum back-pressure (1.5 bar).

Maintenance Tips
1
Inspect the tubing and fittings regularly. Replace the tubing immediately if you see leaks or wear.
2
Clean the ORP probe as described in the manufacturer's manual to keep readings accurate.
3
Refill the chemical tank before it runs empty so the pump does not draw air and dosing stays continuous.
