ABSTRACT:
A coil and cabinet assembly for an air handler is provided in which the refrigerant coil is disposed diagonally within a coil section of the cabinet, the coil having a drain trough for collecting condensate when the air handler is in its upright vertical disposition, a second condensate drain trough adapted for installation in the cabinet at the opposite edge of the coil when the cabinet is to be installed in an inverted upright disposition, both drain troughs having drain outlets projecting from the front face ends of the troughs and extending at their respective locations through lower and upper detachable cross members extending between the opposite sides of the cabinet. The coil also has connected thereto refrigerant liquid and suction gas line fittings which project through one of the detachable cross members, the front face of the cabinet including, along with the detachable cross members, detachable access panels covering the area between the cross members, these access panels being devoid of openings or knockouts to accommodate the refrigerant line connections and drain outlet connections. Thus the projections of the drain outlets and refrigerant line fittings cooperate in holding the coil in its installed position in the cabinet and avoiding the usual requirement of providing panels with patch plates and knockouts.
