STANDARD FEATURES
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.
