I'm looking for this manual also as I lost the original in a move recently. The settings I don't know are F8, F6, F4, F2.There are also settings of how the tub operates (cycles),.EC= Economy,...SL=Sleep mode and ST= Standard, but I have no idea what they do?? The other settings are simply jets on/off, temp of water up/ down with the arrow keys and the light on/off. I have to say it's been a great tub and I've had no issue with it at all,.but it's always been indoors. I guess I'm lucky!! Please if anyone knows or has this manual can you post a link for download or if anyones knows what the above controls do,..please post that.
Thank you very much and have a great day!!
John
