Thanks, I got it
I believe the Aqua one is sold as Via Aqua in the US. They give you a double sided information sheet full of vague instructions and diagrams.. They gave two priming options. First one which I did was to open the screw top priming lid and manually fill to the brim with water. Then turn power on. Nothing. So I tried the second option of disconnecting the outtake pipe and sucking on it untill the the intake tube filled with water and flowed out of the outake. Yeah, it worked! I did email there website, but am still waiting!
Thanks for you help guys!
