To remove larger debris missed by the primary filtration system, the 

control system can activate a secondary filtration system. These cycles 

utilize Jets Pump 1 and the second filter cartridge to quickly “skim” the 

water of large debris and minimize their “bath-tub ring” effect.

B. 

Your new spa includes a

 24-hour primary filtration system, which 

filters the water continuously (factory default). The circulation pump 

draws water through the skimmer bag and one of the two filter cartridges 

to effectively remove small debris in your spa. The factory default setting 

is PF6. This setting should not be altered. Running the circulation pump 

less than the factory recommended time will result in issues with water 

quality maintenance.

Note: The 24-hour primary filtration system also supplies heated water to 

the spa when the heater turns on.

To remove larger debris missed by the 24-hour primary filtration system, 

you can program a secondary filtration system. The secondary filtration 

cycles use Jets Pump 1 and the second filter cartridge to quickly “skim” 

the water of large debris and minimize their “bath-tub ring” effect.

To make changes to the primary filtration cycle, follow the steps below.

A.  Press the 

Menu ( 

 ) button once to access the 

program settings. The LED screen will display “PF.”

B.  Press the 

Warmer (   ) or Cooler (   ) button to prepare the 

system for changes. The LED will display the last cycle programmed 

and will blink once to indicate the system is ready to accept changes.

C.  Press the 

Warmer (   ) or Cooler (   ) button to scroll through the 

cycles, PF0 to PF8, Figure 2.

D.  Once a cycle is selected, press the 

Jets Pump 1 ( 

 ) button to 

confirm the selection. You must press the 

Jets Pump 1 ( 

 ) button 

to confirm your selection or the current settings will remain active.

E.  The display will show the new cycle selected and it will blink twice to 

indicate that the change has been accepted.

Note: If no button is pressed within 5 seconds of each selection the 

screen will revert back to the Main Menu and the current settings will 

remain active.
