Setting the redox level (redox kit option)
The redox level tells you the oxidation potential, i.e. the disinfectant capacity of the water.
Setting the redox set point is the last step in setting the AquaRite LT.
To find the optimum redox level for your pool, follow the steps below:
1) Start up the pool filtration system (the salt in the pool must be evenly dissolved).
2) Add chlorine to the swimming pool until it reaches 1 to 1.5 ppm. This level is achieved with (approximately 1 to 1.5 g/m
The pH level must vary between 7.2 and 7.5.
3) After 30 min. Check whether the level of free chlorine in the pool (manual DPD1 test kit) is between 0.8 and 1.0 ppm.
4) Look at the redox value on the screen and enter it as the redox set point.
5) The next day, check the free chlorine levels (manual DPD1 test kit) and the redox level. Increase / reduce the setting, if required.
Remember to check all your water parameters at regular intervals (2-3 months) (see table) and adjust the redox set point according to
the steps listed above.
