Hook up was pretty easy. There are no instructions at all. To bleed the system, open the flow gauges. Take the red collar off and turn just till it flows. Also, the shut off valves are NOT tapered. They require a gasket. I got mine from the city water department that are used for water meters. Fit great. And it says stainless. The valves are not. I chipped the coating off and it was copper coated. It's not a name brand. It's not branded at all. Good unit so far. But there is a reason it's cheaper.April 19, 2019. Edit: Unit has made it through one season with out any problems. I did find in trying to fill it, the hose connection is backwards, its Male threads. I had to make a double female hose. and it would not seal. So in filling, it leaked from there. Nothing a rag didn't take care of. I sill like the unit and wouldn't hesitate to buy it again.
