Foamy Beer Kegerator

Help with my foamy keg kegerator refrigerator and psi?
So we just got a barrel and a Kegerator, a half barrel. Everything is connected, and the ISP is between 10 to 12 range as the instructions indicate. When the poor of the project, leaving almost nothing but foam. I've seen a lot of answers to this problem, but I'd like a little more. The barrel is so cold at the dealer today, the bar says it's 40 degrees and rapid cooling, everything is connected well and I said, the PSI is about 11 now. Only vessels of foam slowly dissolves, leaving some flat beer in the background.
There are a lot of excess pressure in the barrel! Turn off the gas and vent the pressure of the barrel of the ear, near the faucet. When the pour stops, turn the gas back on. And, when you pour, make sure you open the faucet until the end.
