spa’s control system is factory-programmed with one filter cycle
that will run in the evening when energy rates are often lower. The
time and duration of the filter cycle can be set according to your
needs. In addition, a second filter cycle can be enabled. Filtration
time may need to be increased with heavy bather load.
See instructions for setting filtration cycles, see your owner’s manual.
