Please note the following recommended water chemistry parameters are for residential pool /
spa applications only. Follow local regulatory guidelines for any commercial pool applications.

Parameter Units Min Ideal Max Min Ideal Max
Free Chlorine ppm mg/L 1.0 2.0 - 4.0 5 2.0 3.0 - 4.0 10
Combined Chlorine ppm mg/L 0.0 0.0 0.2 0.0 0.0 0.5

Calcium Hardness ppm mg/L 150 200 - 400 1000 100 150 - 250 1000
Salt ppm mg/L 2000 2500 - 4500 ** 2000 2500 - 4500 **
Cyanuric Acid (stabilizer) ppm mg/L 0 30 - 50 *** 0 30 - 50 ***
** Typically 6,000 ppm (mg/L) or less is recommended; unit can operate with levels as high as 35,000+
ppm (mg/L).
*** This is dictated by state or local codes but is typically 80 ppm (mg/L).
See "Basic Water Chemistry" and "Using the Saturation Index" sections later in this manual for further
information concerning pool / spa water chemistry maintenance requirements. Refer to the
"Troubleshooting" section for assistance with resolving low or high chlorine issues.
