A:AnswerI looked at the owners manual at insigniaproducts.com and they state that the draft tower is rotated into place.
Step 4 of installation---Rotate the draft arm 60 degrees until the tap is facing the front. It may
take some force.
There is nothing listed about holding into place with 4 screws.
A:AnswerNo. "Holds a variety of keg sizes (1/2-barrel (15.5 gal.), 1/4-barrel short or slim (7.8 gal.), 1/6-barrel (5.2 gal.) or 1/8-barrel (4.0 gal.))."
A:AnswerYou can choose either. At first I put mine inside because I thought it was easier to put together. It comes with a bracket which is ready to hook on behind the cooler so I now have it outside. I did research and it said it us recommended to have it outside
