If the pH control point is active in the chemical feed mode for more than 30 minutes, the main
alarm will turn ON and will shut off both the acid and oxidation pumps.
If the ORP control point is active in the chemical feed mode for more than 30 minutes, the main
alarm will turn ON and will shut off both the acid and oxidation pumps.

Silence
If there is an alarm, press the Alarm Silence button on the operator interface panel (See Fig. 2) to
silence the alarm and a red indicator light on the button will be on.
Don’t forget to turn off the
“Alarm Silence” button after the problem is fixed.

Reset
