WINTERIZING
In case of pool winterizing (draining and/or stop of the filtration), achieve the following operations :
✓ Remove the pH probe of the pipe.
✓ Keep it in his original protection filled with city water (or in a glass), in a place where it will not freeze
during winter.
✓ Rinse the flexible pipe of the peristaltic pump with clean water. Put a tin of water in the place of the pH
corrective agent tin and use the function “MA” of the pH control menu (see § 4.2, p.18).
CALIBRATION OF THE Ph PROBE
The pH probe is submitted to the referential curve which moves in the time, depending on the using of the
pool. For an optimal regulation, it is important to proceed to a calibration each starting of the swimming pool
or changing of the probe.
Before proceeding to a calibration, provide you of pH7 and pH10 standard solutions.
✓ Reach the setting menu and then press 3 s on the key .
✓ Select the « CA » code using the keys and valid by .
✓ The screen flashes « 7,0 », the first calibration point.
✓ Dip the pH probe in the pH 7 solution and valid by .
The displayer will show alternatively 7,0 and – flashing during the calibration (1 to 5 minutes)
If the measured value is correct, the device shows « oh » and then displays the value 10.
✓ Rinse the pH probe in the water and drain it without drying it with a rag.
✓ Insert the pH probe in the pH 10 solution and then valid by .
The displayer will show alternatively 10 and - - flashing during the calibration (1 to 5 minutes).
If the measured value is right, the device shows « Oh » and then fall over towards the current display of the
pH.
Note : the probe being in the pH 10, the device flashes 10, because it measures a high pH. The pH high alarm will
disappear from the real measure of the swimming pool.
If one of the values is incorrect, the device shows « Er ». Your pH probe is probably no more usable (lifespan),
to proceed to its replacement, contact your professional.
✓ Remove the cork and then put back the probe on the probe holder.
