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.
Si = pH + Ti + Ci + Ai - 12.1

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.

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 20).
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 “bal-
ance”. 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.
