Hayward Pro Logic Models: PL-PS-4 PL-PS-8 PL-PS-16 PL-PS-16V Installation - Page 6

1. Preparing Pool/Spa Water General Water Chemistry Salt is required only if you are using the chlorinator features on the Pro Logic Control. If you are NOT using the chlorinator, it is recommended that you follow all of the other chemistry recommendations besides salt. Refer to the description of the Pro Logic configuration menu for information on enabling/disabling the chlorinator (see page 24). Water Chemistry The table below summarizes the levels that are recommended by the Association of Pool and Spa Professionals (APSP). The only special requirements for the Pro Logic are the salt level and stabilizer. Saturation index The saturation index (Si) relates to the calcium and alkalinity in the water and is an indicator of the pool water "balance". Your water is properly balanced if the Si is 0 ±0.2. If the Si is below -0.2, the water is corrosive and plaster pool walls will be dissolved into the water. If the Si is above +0.2, scaling and staining will occur. Use the chart below to determine the saturation index. Si = pH + Ti + Ci + Ai - 12.1 ºC ºF Ti Calcuim Hardness Ci Total Alkalinity Ai 12 53 .3 75 1.5 75 1.9 100 1.6 100 2.0 16 60 .4 125 1.7 125 2.1 19 66 .5 150 1.8 150 2.2 200 1.9 24 76 .6 250 2.0 200 2.3 250 2.4 29 84 .7 300 2.1 400 2.2 34 94 .8 600 2.4 300 2.5 400 2.6 600 2.8 39 103 .9 800 2.5 800 2.9 How to use: Measure pool pH, temperature, calcium hardness, and total alkalinity. Use the chart above to determine Ti, Ci,and Ai from your measurements. Insert values of pH, Ti, Ci and Ai into the above equation. If Si equals .2 or more, scaling and staining may occur. If Si equals -.2 or less corrosion or irritation may occur. -.2 0 .2 CORROSIVE SCALING OK The pool's chemistry must be balanced BEFORE activating the Pro Logic's optional chlorinator function. NOTE: If the pool does not have new water, add metal remover and non-copper based algaecide to the pool, per manufacturer's instructions. This ensures a quick, troublefree transfer to the Pro Logic system. 3 if any output is configured as a variable speed pump VSP Speed % Toggle between % and RPM Move to previous/next configuration menu This is the unit of measure for displaying the speed of the variable speed pump.

Maintenance Menu (only displays if Sensing System is enabled) The Maintenance Menu will be displayed only if the optional AQL-CHEM is used and the Sensing System is enabled in the Chemistry Config. Wizard. This menu is used to perform functions relating to the AQL-CHEM ORP and pH sensing kit. pH Calibration Wizard, + to enter Push to access pH Calibration Wizard Move to previous/next menu item Use this Wizard to calibrate the AQL-CHEM's pH probe. This requires a manual pH test of the pool water using a dependable red phenol test kit. Clean Probe Wizard + to enter Push to access Clean Probe Wizard Move to previous/next menu item Use this Wizard to clean the AQL-CHEM's ORP and pH probes. The probes must be clean and free from oil, chemical deposits and contamination to function properly. Slow response, increased need to calibrate, and inconsistent readings are indications that the probes need to be cleaned. 40
