Converting a water cooler to bottleless?

I have a Whirlpool hot / cold water dispenser. I am about to get a reverse osmosis water system installed. I would like to plumb the r/o water into my water cooler so I will no longer have to buy / carry the 5 gallon jugs. I have found brand specific conversion kits for other cooler brands. Does anyone know of a kit for Whirlpool or a generic conversion?
