Changing the pH Setpoint The HCC 2000 is preset from the factory to maintain pH at 7.5. To set pH control at a different level, perform the following: 1. Press the pH Setpoint Adjustment Button (#4) until the green "SET" LED is illuminated. 2. Press the arrow-shaped pH Channel Increase Button (#2) or pH Channel Decrease Button (#3) until the digital display matches your desired pH control level. 3.

Changing the ORP Setpoint The HCC 2000 is preset from the factory to maintain ORP at 650 mV. This is the generally accepted world standard for safe drinking water. In order to meet Health Department standards for a particular pool or spa, the ORP setpoint may be changed to maintain a desired sanitizer level by performing the following: 1. Manually test pool or spa to confirm that the current sanitizer reading (chlorine, bromine, etc.) is the level you wish to maintain. 2. Note the ORP reading displayed by the controller. 3. Press the ORP Setpoint Adjustment Button (#8) until the green "SET" LED is illuminated. 2. Press the arrow-shaped ORP Channel Increase Button (#6) or ORP Channel Decrease Button (#7) until the digital display matches the ORP reading previously noted. 3. The controller will automatically return to the normal operating mode after twenty seconds, storing any changes. The ORP setpoint should be changed as needed to maintain sanitizer residuals in conformance with Health Department standards. Manually Activating pH Feed To manually enable the pH chemical feeder press the pH Channel Mode Selection Button (#5) until the green "MANUAL" LED is illuminated. The chemical feeder will operate continuously for 30 minutes, and then automatically revert to "Auto" to prevent accidental over-feeding. CONTENTS COPYRIGHT 2010 HAYWARD INDUSTRIES, INC.
