A refrigeration system includes an evaporator coil with a drain pan having alternative drain openings which receive movable primary and secondary drain plugs. A drain pan for use with horizontal A-coils is provided with alternative drain pan openings permitting a variety of configurations whereby the evaporator coil may be oriented in the space conditioning system in the most effective manner depending upon on-site conditions. A combination horizontal coil support and drainage duct with coil baffle provides a channel for effective communication of drainage fluid from the coil to the drain pan.
