To ensure your device continues to perform optimally, the pH probe should be calibrated if the displayed value differs from the measurement in the pool.
To do this, go to the “pH calibration” menu and follow the instructions.
Two methods are available:

“Pool value”: with this method, the pH is measured in the pool using a photometer and compared with the probe signal. This is the most accurate method.
“pH 7 buffer solution”: with this method, a buffer solution with a known pH of 7 is used. This method is less accurate, but it has the advantage of not requiring a photometer.

For your device to inject the correct amount of chlorine, the redox setpoint must be properly adjusted.
First, ensure that the pool water parameters are correctly set:

• Total alkalinity (TAC): minimum 80 mg/l
• pH: 7.0 – 7.4
• Indoor pools: chlorine level (DPD1): 0.8 – 1.2 mg/l
• Outdoor pools: stabiliser 30–50 mg/l, chlorine level (DPD1): 1.5 – 3 mg/l

If necessary, manually adjust these parameters using the appropriate treatment products. Then start your device while stopping the chlorine injection. After a few minutes, the redox probe reading (in mV) will stabilise.
Record the value measured by the probe and enter it as the new setpoint.

To keep your device in perfect working condition, it is recommended to carry out the following tasks:

Weekly checks

• Ensure your filtration system is in perfect working order.
• Check the pH and chlorine levels, preferably using the BAYROL Technik Electronic Pooltester.
• Visually inspect the installation for any leaks in all components, lines and pipes.

Annual maintenance

• Replace the pH probe and calibrate it using pool water.
• Replace the redox probe and adjust the correct mV setpoint. Make sure the chlorine level in the pool water is at the desired level.
• Replace the peristaltic tubes of the dosing pumps.
• Check the injection lances, suction and discharge hoses for pH corrective product and liquid chlorine, and replace them if necessary.

In case of active winterisation

The pool filtration system remains in operation.

• Stop the filtration pump.
• Rinse the dosing pump pipes with clean water (see “Special functions” menu).
• Empty all dosing pump pipes.
• Remove the probes from their holders and store them in their container, preferably filled with saturated KCl solution or clean pool water. Store the probes in a cool, dry place, protected from frost.
• Insert ½" plugs in place of the probe holders.
• Store the containers of pH‑Minus Liquid Domestic or pH‑Plus Liquid and Chloriliquid in a cool, dry place.

In case of passive winterisation

The pool filtration system is switched off.

• Stop the filtration pump.
• Rinse the dosing pump pipes with clean water (see “Special functions” menu).
• Empty all dosing pump pipes.
• Close and drain the filtration system. Ensure that the entire pool circulation system is drained as much as possible. Refer to your installer’s instructions.
• Remove the probes from their holders and store them in their container, preferably filled with saturated KCl solution or clean pool water. Store the probes in a cool, dry place, protected from frost.
• Store the containers of pH‑Minus Liquid Domestic or pH‑Plus Liquid and Chloriliquid in a cool, dry place.
   

A software update for your device is required. To do this, please download the latest version below and follow the instructions provided in the update manual.
