If your kegerator came with a flex tube directing cold air from the evaporator, you are in good shape. If not, you will have to install a small
15 CFM blower and flex tube and force this up into your tower. Bridge the area from the kegerator to the bottom of the bar with the same size I.D PVC as the tower. Wrap the outside of this with insulation and try not to move the kegerator to much after install. Shove the flex tube into the tower as far as it will go without blocking the end to direct cold air to the shank.
