Hot Tub Heater Connection

389 Views 2 Replies 2 Participants Last post by  lovetobuild
I am replacing my heater manifold for my hot tub and I was wondering how I can be sure how to hook up the flow sensor wiring. There are two posts on the heater to attach a black and red wire. I don't know how to know which wire goes on which post.

Thank you

If it's 240 volts it does not matter which one goes where.
Thanks Joe. I appreciate your help.
