Abstract: An air handling apparatus and method for installation where a cabinet is connected to a mounting plate with a mounting bracket, the mounting plate is attached to an electrical equipment enclosure. Gravity and latching screws secure the cabinet to the mounting plate and also facilitate a seal between the cabinet and the enclosure. After connection of the cabinet to the mounting plate, the mounting plate and mounting brackets are concealed from view by the cabinet and enclosure. The mounting bracket is a combination of hooks and slots. Panel elements of the cabinet are interconnected using a combination of hooks and slots with seals compressed between the panels. The cabinet includes a horizontally disposed evaporator coil, the evaporator coil between an evaporator blower and a condenser blower. Air conditioning elements are vertically stacked within the cabinet. Airflow in the cabinet is generally upward in both the internal and external circulation regions.
