Some condensation accumulating on initial startup should be expected. Lots of guys use Damp Rid to reduce and control it over the long run. Many times excessive condensation can be the result of an air leak at the lid seal or where the collar is attached to the freezer. Even a tiny air leak will lead to excessive condensation. A collar needs to be constructed carefully to insure that the sealing edges are not warped or otherwise out of square. The lid seal will take up a lot of the imperfections, but there is a limit. Put a light inside the freezer in a darkened room and check the sealing surfaces closely for light leakage. If light can get out, air can get in for sure. No light leakage is not an absolute indication that there is no air leak, but it's quick and easy to do. I would let the freezer run for a few days first and see if the problem gets worse or not before taking any corrective action.
