A pre-chiller for an incoming fresh water supply of an ice maker. The device is connectable onto an upright surface of the existing ice maker, a separate wall surface or the like and includes a chamber for receiving and holding cold waste water discharged from the ice maker during each ice making cycle. A standpipe connected within the chamber drains the waste water while automatically maintaining waste water level within the chamber. A fresh water cooling conduit, preferably comprised of a plurality of enlarged hollow stainless steel cylinders connected for series flow of fresh water therethrough, is positioned submersed in the cold waste water within the chamber. During each ice maker cycle, cold waste water is delivered into the chamber and fresh water being held for chilling within the cooling conduit by the surrounding waste water is moved into the ice maker water inlet. A time delay between start up of the ice maker water pump and chilled fresh water delivery is also provided to pre-chill the evaporator plate within the ice maker, which reduces expansion valve frustration.
