CAL
The pH probes/sensor has been factory calibrated. However it is a good practice to check the adjustment for the
probe periodically (say 6 months or earlier if required). The probe should be cleaned first (refer under Maintenance
page 13 for cleaning) and allowed to settle down for about 4-5 minutes before adjusting/calibrating. Calibration
solution is available via AstralPool as a spare part.
pH When the controller is in Manual Off mode, remove the pH probe from the pipe line (shut off the filter pump and
close any isolation valves to avoid water spill), clean the probe (see under Maintenance) and place it in a 7.5 pH
