Operating Your Spa
Setting Filtration Cycles
Your spa will automatically filter itself twice a day. To set the filtration time, turn off the power to the spa at
the GFCI breaker. Turn the GFCI breaker back on at the time of day you would like to start the filtration cycle.
The first cycle will start after the spa is powered up. The second filtration cycle will begin twelve hours later.
The filtration cycle duration is preset to 2 hours (F2). To change the duration of the filtration time, press the
Temp pad, then press the Jets pad. Press the Temp button again to choose from 2,4,6,8, and 12 hours twice a
day (FC = Filtration Continuous).
After selecting the desired filtration cycle duration, press the Jets pad to exit the filtration program. The
circulating pump and ozone generator (optional) will run during filtration cycles.
NOTE: The filtration cycle settings of F8 and FC are only intended for use with the optional Spa Cal™
Filtration System.
