NOTICE:
Failure to adhere to the listed water chemistry parameters may result in premature
failure of the heat exchanger and will
void the warranty.

WATER CHEMISTRY PARAMETERS
Table 10.
ALKALINITY High or Low:
“Total alkalinity” is a measurement of the total amount of alkaline chemicals in the water, and
control pH to a great degree. (It is not the same as pH which refers merely to the relative
alkalinity/acidity balance.) Your pool water’s total alkalinity should be 100 - 140 ppm to permit
easier pH control.
A total alkalinity test is simple to perform with a reliable test kit. You will need to test about
once a week and make proper adjustments until alkalinity is in the proper range. Then, test only
once every month or so to be sure it is being maintained. See your local pool dealer for help in
properly balancing the water chemistry.
