Jacuzzi J-145 Owner's Manual page 25

15. Establish a sanitizer reading of 3.0-4.0 ppm free chlorine or 2.0-
4.0 ppm bromine, then allow the hot tub to set undisturbed for 8
hours. Retest water after 8 hours to determine if sanitizer levels
are stable. If sanitizer levels are stable, your spa is ready for use.
To ensure healthy water conditions, always maintain a constant
sanitizer reading within the levels recommended on the inside cover
of this manual. If sanitizer levels are not stable at this time, it will be
necessary to repeat this procedure in its entirety (steps 1-15) until
stable sanitizer readings are achieved.
16. After adequate sanitizer levels are achieved, close all spa air controls
to maximize heat retention when spa is not in use.
