the condensation happens when the room the vino is in is relatively warm.
my studio is the warmest room in the house (from all of my electronic,4 computers,dj and studio gear) and it was the first place i tried my vino. the condensation poured like a faucet in there!
i moved it out into the bedroom where it is not warm and the condensation stopped.
i suggest to keep it in the coolest room in the house (most likely why fellas with vino's in the basement work so well). also, make a trouft that funnels any would be condensation into a bowl with florist foam or beads. that's what i had to do before moving it into another room.
the hotter the outside air, the harder the vino has to work to keep the desired coolness up to temp. causing more cold air to push out, causing more condensation.
i am not an expert but i did stay at a holiday inn express, never
