I am wondering if anyone has the schematic to reflect the amperage jumper settings for the Jacuzzi j-375 or any 300 series tub. I want to change the setting from 50 to 60 amps but the owners manual does not indicate how to do this.

You sure you don't mean hz?

No, I am referring to amps. If you have a 60 amp breaker, the heater and both pumps will work all at once. With the 50 amp setting, if you have both pumps running with the #1 pump at high speed, the heater does not function.
