I just purchased a brand new whirlpool WZC3115DW model and want to build my keezer. I would like to not have a collar and just drill thought the front wall of the freezer case for the faucet shanks. I'm worried that there are condenser lines running through the front wall of the freezer and I may damaged them. Does anyone have info for this particular model? I can't find anything about this models condenser lines anywhere on the web.
