DESCRIPTION

548J***D units are one--piece, two--stage heat pump units

that are low profile, prewired, tested and charged at the

factory. These units have field convertible supply and return

openings and are intended for installation on a roof curb

accessory (ordered separately), or for slab mounting (for

horizontal duct connections). Units are designed to accept

field--installed electric heaters. Units may be ordered with

various factory--installed options. Field--installed accessories

are also available.
