Cub here - There is a button on your spa control that turns off the tub completely. This feature should be in your manual and I use it to change my filter without turning the breaker off. The tub must be off, otherwise the suction is too strong to move the filter basket....
It's right.
I check my French manual and I found something I miss. But...
The said to press the #3 button 5 seconds to put the spa in "wait mode" for 30 minutes. In the French guide they said the heater; filtering process can start during this period??? "Si le chauffe-eau est en marche lorsque le système est mis en veille, le cycle de filtration, le mode antigel et le chauffe-eau peuvent démarrer pendant cette période d'interruption."
But I check the English version on the Arctic web site, and they said "... Heater, filter ... can't start during this period."
The French guide is not well translated!
TOM! You have a job to do!
