I just completed a new pool install in March this year that included among other things an SWG. I had the ground leveled, pool frame & liner installed but I completed the plumbing, deck, fencing, landscaping and electrical installation.

If you can glue and measure PVC piping the plumbing is no big deal. The Aquarite had directional arrows telling you which way the water should flow thru the cell and flow switch.

The Electrical is more important. There are strict pool wiring codes provided by the NEC. It's important that the entire system be grounded and bonded. I used THWN/THHN wire for all of my 4 circuits. All are protected by GFCI breakers. There is a separate ground rod at the pump house and a bonding loop that connects, pump motor, pool frame, deck & Aquarite.
