default (when pH exceeds setpoint, the pH chemical feeder is activated). If the

sanitizer or other factors of the application cause the pH to decrease, base feed mode

must be selected.

Note: In certain unusual applications, pH correction may be required in both acid

feed and base feed modes. The third relay can be programmed as described later in

this manual to accommodate this requirement.
