Operating Your Spa
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.
Safety Suction System
Your new Cal Spa is equipped with a state-of-the-art Safety Suction System. This will automatically shutdown
the spa in the event of a filtration or suction restriction, and display SF on the topside control panel. If this
happens, check all suction fittings and filter cartridge(s) for obstructions. Then, reset the system by pressing any
control panel button.
