Plug it in, take the outflow tube and start sucking until water comes out. Easiest way to prime any canister filter.
I know people will say, try tilting it, try opening and closing 9 times, prime, fill the hoses under the water and then attach quickly, blah, blah, you can spend hours messing around doing all those thing or just grab it and suck. Works every time.
