Abstract
In an ice maker with a sump below an ice formation device and a pump for recirculating water from the sump to the ice formation device, water can drain through a stand pipe drain. A drain fitting is disposed in relation to a stand pipe such that the drain fitting's upper end is disposed above the top of the stand pipe, its lower end defines a water inlet adjacent the bottom of the sump, and its perimeter wall extends 360° about the stand pipe to define a drain passage extending from the water inlet to the top of the stand pipe. The upper end of the drain fitting defines a siphon release opening. The stand pipe drain can also include a valve for adjusting the drain between an overflow drain configuration and a siphon drain configuration.
