l1  Lock Out: disables all spa functions to permit filter 

cleaning.

l2  Lock Mode: disables the jets to prevent unauthorized use 

of spa. Filtration/heating cycle will continue to operate as 

programmed in this mode. The temperature display flashes when this 

function is enabled. Example: The “F3” filtration/heating cycle was 

enabled prior to choosing lock mode. The spa continues to perform 

the “F3” cycle until lock mode is canceled, allowing another cycle to 

be selected.

To set a time for the first filtration/heating cycle, simply turn power on to 

the spa two minutes prior to the desired time. Example: If you desire your 

first filtration/heating cycle to begin at 10:00 AM turn off power to the spa 

and turn it back on again at 9:58 AM. 

note: Start time is approximate and may vary slightly from day to day.
