which bit goes where

[barryg]

Good morning all,
I am looking for information to help me install my new acquisition. I have an Intex 12 x 24 foot above ground pool. With it I have a Pentair Sat-rite 5P2RD-1 filtration pump.
A Pentair Triton 11 19 inch sand filter and a Blue Lagoon 75000 UV-C timer. Hopefully, later on this week I will be buying my heat which will be an air heat pump.
I also have a gate which things connect to. I have some pipe work including valves bur I suspect that the plumbing will need to be re done, it was hard piped in its previous home.
Can anyone help me please as to which bit goes where. The ground is all prepared with insulation boards in place. Any advice would be greatly received.
Many thanks.
