CAUTION: To prevent the unlikely possibility of contracting a
waterborne illness, maintain water chemistry within step 6
parameters. If you or other bathers experience such a condi-
tion, discontinue use and seek medical attention.
15. Establish a sanitizer reading between 3.0-4.0 ppm chlorine or
2.0-4.0 ppm bromine, then allow the spa 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 sani-
tizer reading within the levels recommended by the Association of
Pool And Spa Professionals/USA printed on the inside cover of this
manual. If sanitizer levels are not stable at this time, it will be neces-
sary 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 con-
trols by rotating them clockwise to maximize heat retention when spa
is not in use.
