Multiple position leg assembly for a heat exchange unit

摘要

A multiple position leg assembly for a heat exchange unit is disclosed. A support surface has a pair of slots which coact with a leg such that the leg has a shipping position wherein it does not extend beyond the bottom of the unit and has a support position wherein it is securely fastened in the slots of the support surface to maintain the unit a preselected distance from a mounting structure. The leg is designed such that internal forces act to secure narrowed portions of the leg in the slots to provide a secure support for the unit.
