Lockout Modes L1 - L2
Additional modes (L1 - L2) are special modes designed for servicing/cleaning. Refer to the options
below:
L1
L2
Lock Out (disables all hot tub functions to permit  lter cleaning or other maintenance) - If the hot
tub is heating when the system is put into lockout mode, the heater will immediately shut off and
the circulation pump will cycle water for 30 seconds to cool the heater element, then shut off.
Lock Mode (disables the jets and light buttons to prevent unauthorized use of the hot tub) - The
lter cycles and heater will continue to operate as programmed in this mode. Example: The “F3”
lter cycle was enabled prior to choosing the lock mode. The hot tub continues to perform  lter
cycle “F3” until lock mode is cancelled, allowing another  lter cycle to be selected.
The temperature display  ashes when either Lock Out Mode is enabled.
