Just hooking up hoses to front matrix and I think I may have the flow and return swopped can anyone advise whether the top spigot is flow or return? https://goo.gl/photos/hSjxsnTAJ23LkPfJA
Looking at the LP diagram would suggest you have them A for E, the top hose goes to the Left of the unit and the bottom hose down and to the right of the unit. Looking from the bumper.
