Important:
The sensor must be calibrated when your pH First is first installed and
ideally every two months there after.
> Calibration must be done each time your pool is restarted at the beginning

> The procedure should be repeated if an abnormal amount of corrective solu-
tion is consumed (pH minus or pH plus).
> The calibration procedure can only be carried out when filtration is stopped.
> Before calibrating, stop filtration and close the valves so as to isolate the
pH sensor holder from flowing water.
