WARNING: Never leave an open spa unattended, especially if there are children present!
BUILDING A SANITIZER ROUTINE
During the first month of ownership, measure the sanitizer residual daily in order to establish standards for User Load and Usage Time versus Sanitizer Needed.
• The User Load of the spa is the number of times anyone enters the spa.
• The Usage Time is simply the amount of time a user spends in the spa.
• Sanitizer Needed is the amount of Free Available Chlorine (FAC) needed to accommodate the number of users and their combined usage time.
For example, two spa users who regularly use the spa once an evening for twenty minutes create a specific and somewhat consistent demand on the sanitizer. During
the first month of ownership, these two users can determine exactly how much sanitizer to use in order to maintain the proper residual. If, at any time, the user load
and/or usage pattern changes dramatically (invited guests), the amount and frequency of sanitizer required increases dramatically.
The greater the usage time, or the bather load, the faster the residual value is diminished.
