I am surprised that Franklin said you needed a flow inducer. They claim their 2 HP and smaller motors are so short that they do not need a flow inducer. However, the temp of the water has less to do with motor cooling that where the water enters the well. With the pump set at 100’, if all the perforations are below 100’, or if it is a rock well open-ended at the bottom, then you don’t need a flow inducer.
Only when a pump is fed from the top is a flow inducer needed. I don’t think you need to worry about that.
Now setting the CSV1W about 8’ below the ground means you will only lose 3 PSI. I don’t think that is even worth adjusting for. But if your turn the set screw one full turn to the right, it will be set a t 55 PSI.
