I’m following the DIY Hot Tub Winterizing document I got from Aqua-Tech Service. One step says:
“Next, locate your spa heater, and turn it off. … Activate the spa’s air blower and let it run for approximately 30 seconds.”
I looked at the heater on my 2013 Sundance Optima and I don’t see any switch or plug to turn off the heater. Is it OK to turn the power breaker back on for 30 seconds with an empty tub or can you tell me how to shut off the heater?
