The Gold series air handlers are completely redesigned for easier installation and improved performance. A rust-free, anti-slosh, positive-flow drain pan quickly removed condensate water and a third drain hole can be employed to further increase repid drainage. To better accomodate a variety of installation situations, each drain hole is reinforced and has an external stop to prevent over tightening of the screw-in hose barb. Each drain hole can accept either a straight hose barb or a 90-degree hose barb. In addition, the vibration-isolation mounting hardware can be attached at a variety of locations around the perimeter of the drain pan.
