I was given a couple of Delonghi Pinguino portable Air conditioner units but did not get the manuals with them. It is model # PAC75U. Does anyone have a parts list they could scan and email to me? I need the reducer, the window unit, and also wheels. Any help would be greatly appreciated. I found a company in Canada that sells parts, but they have several reducers from $7.50-$30 and they both look the same. Finally, is the window unit a universal product that fits any size window whether vertical or horizontal? Thanks again.
