No beer from King Keg

Hi everyone,
I hope someone out there can help.
I brewed a beer in a fermenter until gravity was stable at 1006. (7days) A brew belt was attached to a King Keg top tap and the beer was transfered to it. I took the brew belt off after two days and left the beer in a cool place. When I tried to sample the beer a few days later nothing came from the tap so a gave it a blast of co2 but still nothing so I gave it a further 2 1sec blasts but still no beer from the tap.
What am I doing/or what's wrong?
Kevin

Don't you have to prime a king keg? Assuming you did prime it, isn't it still going to take 2-3 weeks to carbonate?
