Welcome to our forum.
When I reached the "critical point" during a blizzard & resulting 40 hour power outage last weekend, I wasn't sure what to do w/my 05 Sundance Optima tub. Not having a compressor to blow out the lines, I wasn't sure what to do. I finally just drained the tub to hopefully minimize freeze damage. (I have since refilled the tub, and it appears I did dodge the bullet ). Was that the right thing? Going forward; I have a generator being delivered today. I can't seem to find amp draw for various pump motors in my manual - anyone know offhand? Also, is there a way to disable the heater without going into the control panel? (It's a little difficult to access). I see running in "Economy" mode helps, but manual says the heater would still run during filter cycles. Can I just program NO filter cycles, or is there an easier/better way? Any input/suggestions would be greatly appreciated. Thanks!!

I'm interested in this thread as my hottub is 2.5hrs away from my main place, and it gets into the teens most nights during the winter. What do you mean by 'critical point'?Personally, I think you made a mistake by draining the tub. You had a big mass of stored energy in that tub. A tub at 100+ degrees should be able to stay above 32 degrees for quite a while. Draining the tub (and not blowing out the lines) literally removes all of that, and you'll be left with water in the pumps and lines that will freeze up much faster. I wonder if the tub runs if you disconnect the power to the heater (just pull the plug).
