A TOO HIGH OR LOW pH IRRITATES SKIN
> Ensure that:
- The probe bottle has been removed from the pH probe (see p08)
- The pH probe was calibrated less than 6 months ago (see p36)
- The pH probe is not dirty (see p39)
> Manual control: select “pH-” or “pH+” product according to the type of pH deviation.
> Automatic regulation: check the correct operation of the material
INDOOR DISPLAY - pH reading
The pH is a scale (without any units) measuring the acidity (0 to 7) or the alkalinity (7 to 14) of the pool. The
pH is the concentration of the hydrogen ions. For a swimming pool, the ideal pH which is generally advised
is close to 7.3 (to be confirmed by your swimming pool supplier according to your installation).
Note: the precision of the pH measurement is very closely associated with regular pH probe maintenance.
Checking for any contamination regularly (see p33) and calibrating it before the summer season (see p36)
are recommended.
If the pH value is high or low, check if an air bubble at the bottom of the pH probe is resulting in a bad
measurement. Shake the pH probe (as for a mercury thermometer) so that any air bubbles rise up by
the centrifugal force.
The factory set points of the upper and lower pH alarms are 6.7 and 7.9. These values can be modified via the alarm mode
(see p. 32).
