Polaris air spa blower

[bob22]

My daughter's new home what I've discovered is a Polaris air spa blower, model #516-03, 1.5 HP.
I presume from the name that it blows air into the spa section of the in-ground pool.
How is it typically turned on?

You have a switch by the spa or on the automation control panel to turn the air blower on.

Follow the power cord from the blower and see what boxes it leads to.
