A refrigerant system includes a dual-connection drain pan for collecting and draining condensate from the exterior surface of a cooling coil. The drain pan includes a first channel and a second channel disposed alongside each other and sloped lengthwise in opposite directions to direct the condensate to either one of two drain outlets at opposite ends of the pan. To drain the condensate to a first outlet, a breakaway removable dam between the two channels is left intact to isolate the second channel from condensate so that the condensate drains from the first channel to the first outlet. Permanently removing the breakaway dam and plugging the first outlet allows condensate to drain from the first channel, into the second channel, and out through the second outlet. In some embodiments, the drain pan, including the two channels and breakaway dam, is formed of a unitary piece of a thermoset polymer.
