Step 3
Rinse the sensor in flask 2 (water). Then shake gently to remove excess water.
• The sensor must be calibrated when your pH Perfect is first installed and each time your pool is
restarted at the beginning of the season (with new buffer solutions).
• The procedure is to be repeated if an abnormal amount of corrective solution is consumed
(pH minus or pH plus).
• The calibration procedure can only be carried out when filtration is stopped because of the
dual feed.
Step 4
