Pool Relax Bromine
Bring the pH value of the pool water to 7.2. You can manually dose the pH to do so (see "pH measuring and control module"). If the
pH value differs widely from 7.2, you can use pH-Minus/pH-Plus in a granular form (it is important that you follow the dosing
instructions on the product package). It is important that you check the pH value with the supplied pool tester.
First, bring the bromine value of the swimming pool water to the desired value. (Recommendation: 2-4 mg/l). ATTENTION:
Depending on the pool size and water temperature, this bromine value may not reach its final level until after several days. To
ensure a sufficient degree of water disinfection from the beginning, we recommend an initial disinfection with chlorine, e.g. with
Chlorifix. It is important that you check the bromine value with the supplied pool tester.
When you adjust the pH and bromine value of the pool water, you can simultaneously calibrate the pH and redox electrodes with
the supplied buffer solution. Apply the 1-point calibration method for both electrodes.
The redox value that results when the bromine value of the pool water is adjusted (recommendation:
2-4 mg/l) can be used as the redox setpoint. A precondition is that the pH value must already be close to the setpoint (+/- 0.1) and
the redox electrode must be calibrated with the redox buffer. Under certain conditions, the measurement of the redox potential may
take longer than expected. Please wait until the displayed value of mV has fully stabilized.
As soon as the pH and redox values in the pool water are close to the setpoints, you can set the control of the two control modules
to Auto.
We recommend that you monitor the control behaviour over a period of time and adjust it to the conditions prevailing in the pool, if
necessary. In particular, this applies when the current values in the pool still vary widely from the setpoints.
