Roof assembly for an air handler
First Claim
1. An air handler having a length, width and a height, the air handler comprising:
- a heat exchanger containing a fluid;
an internal panel extending along the width of the air handler, the internal panel includes an upper corner having a landing edge and a lead-in edge, wherein the landing edge extends horizontally and the lead-in edge is at an incline;
a roof rail running along the length of the air handler and being above the landing edge of the internal panel;
a side panel underneath the roof rail and adjacent the internal panel;
a roof above the side panel, above the heat exchanger, and being supported by the side panel and the roof rail;
a gap at the upper corner of the internal panel, the gap is defined by the lead-in edge of the internal panel, the roof rail, and the roof; and
a gasket that at least partially fills the gap.

Abstract
An air handler (or air handler section) includes an enclosure containing various internal HVAC components and a bi-directional alignment system that during factor assembly of the enclosure helps align the enclosure'"'"'s entire roof to the internal components. To help align the roof in a widthwise direction, a tapered lead-in edge in the upper corners of a block-off panel for an evaporator, filter rack, damper, fan and/or other HVAC component engages a roof rail that runs along the length of the roof. The upper corners of the block-offs also include a landing edge that engages the underside of the roof rail to help support the weight of the roof. Cross rails attached to the underside of the roof and extending along the width of the enclosure include an inclined lead-in flange that engages the upper edge of the various internal HVAC components, thereby helping align the roof in a lengthwise direction.
