Hello,

I have a Spa Builders LX-10 110/220 controler/heater but it is wired for a 110 pump. I need to know how to switch it to a 220 pump. I think I can just pull the white (com) wire from the white (neutral) terminal and put it onto the L2 terminal, but I am not sure. If anyone has done this, or knows where I can get the technical manual for the controler I would be gratefull.

Thanks!

white terminal that goes to the motor in question yes.
provided of course, no weirdo went into the back of the motor and switched the wires around from the factory config.
