Abstract
A drain spout that is easy to remove for cleaning and for accessing components behind or proximal to the drain pan. Instead of directly connecting the drain hose to the drain pan outlet spout, the drain hose connects to a drain funnel attached to or formed as a part of the shelf supporting the drain pan. The drain pan itself sits on the shelf and the outlet spout of the drain pan fits within the shelf funnel without a positive connection. The drain pan can be lifted out without disengaging the drain hose.
