Tapping my tap-a-draft

I used my TAD system for the first time the other day and came across a small problem. I unscrewed the cap on the bottle and the pressure released like a soda bottle, but 10x worse, and it was foaming like crazy. I eventually got the tap on and it seems be going decently. I was wondering if I did this the right way or should I have done it differently. Also, the beer seems to come out kind of slow, especially in comparison to my experience with the miller home draft. Any thoughts and/or help is greatly appreciated. Cheers!

My guess would be that you opened the TAD bottle while the beer was at room temp. Try sticking the bottle in the fridge for 24 hours first, and I would think that should help.
