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.

Abstract: This invention relates to cover panels for enclosures, such as those found on the sides or roofs of buildings, which house air conditioning equipment. More particularly, this invention relates to a cover panel for an air conditioning enclosure which both accommodates the penetration of piping through it and allows for access to the interior of the enclosure, subsequent to the hookup of the piping to air conditioning system components housed within the enclosure, without the need to break a piping connection.
