Freeze Protect Over-ride FPO
This function is intended to be used on start-up after a fresh fill if water temp is below 52ºF. The 6 hour dura-
tion of the FPO cycle is counted from the time the unit is powered-up and not from the time of its activation.
By pressing the Jets 1 and Light key simultaneously for 10 seconds, the freeze protect feature will be suspend-
ed for 6 hours. ( the FPO will be activated) This is to allow the installer of the spa to check for normal operation
if the spa is filled with water that is less than the set freeze protect level 52ºF. FPO will appear every 10 sec-
onds at the topside control. To manually go back to freeze protect mode, power down the system and re-boot.
It is recommended that the system be left on low speed and heating in FPO mode.
