How to wire an alternating relay?

Ive never wired one of these before. I wired it like I would a normal relay, switching the coil, but its not alternating. I found a schematic for it and I think I have it figured out but I wanted to get someone else's opinion.

I think I need pin 4 always hot 3 is neutral
pin 5 the float switch to turn it on (and alternate)
jumper between 1 and 5
loads on 2 and 8
and just wondering are pins 6 and 7 a set of normally closed contacts?
