Spa Owner Responsibilities
Balancing the pH level and Total Alkalinity to the “OK” range.•
NOTE: The generation of chlorine from salt will cause the pH to drift upwards
initially. Check the pH level at least once a week after initial start-up, and once
a month after normal use patterns have been established. Adjust as needed to
maintain water quality. An extensively high pH will cause premature failure of
the system, cloudy water, and decreased effectiveness of the sanitizer.
Maintaining low Hardness levels using the Vanishing Act calcium remover as •
needed.
NOTE: The ACE system works best with low levels of calcium and minerals
in the water. Softened water prolongs the life of hot tub equipment, while
enhancing the soaking experience. The ideal hardness level when using the
ACE system is 50 ppm.
Inputting Spa Size and Use Level.•
Checking chlorine level before each use after initial start-up to determine best •
Use Level to maintain healthy water quality.
Conducting a check up every 30 days, which includes testing and balancing the •
spa water, and reconfirming Use Level.
NOTE: The 30-day cycle begins when the Use Level is confirmed at start-up,
and resets any time the Use Level is changed or re-confirmed. The water care
icon will flash as a reminder when each 30-day cycle is over.
Establishing a chlorine residual at start up. •
Manually flushing plumbing lines by super-chlorinating or “shocking” the spa monthly.•
IMPORTANT: Ensure that the chlorine level is always between 3-5ppm before using
the spa. Add chlorine manually if needed.
System Status
Water Care Icon – The water care icon, located on the icon bar below the screen of •
the main control panel, will be illuminated once the ACE salt water sanitizing system
