Abstract
An outdoor enclosure for air handling equipment is adaptable to accept add-on air handling equipment by virtue of a two-position cover panel. The cover panel has a generally rectangular shape and is attached to a side panel of the enclosure. The cover panel is selectively mountable in either a vertical position to cover a fresh air opening through the side panel or in an open position to uncover the opening. The cover is opened by pivoting it about its upper horizontal edge which is located just above the opening and swinging its lower edge outwardly away from the side panel. An add-on mist elimination filter is installed in a generally horizontal position betweeen the cover panel's lower edge and the lower edge of the side panel's opening. In the open position, the cover panel serves as a rain sheltering hood over the filter while the opening allows fresh outside air to be drawn into the suction side of a fan located inside the enclosure. The two-position cover panel facilitates the conversion of the enclosure while minimizing the need for special, single-purpose panels.
