DESCRIPTION
ARI STANDARD
360
The 48HG units are one-piece electric cooling/gas heating units, prewired and
precharged. The 50HG units are one-piece electric cooling/electric heating units,
prewired and precharged. The 48/50HG units have bottom air openings for separate
supply and return ductwork. The 48HGD units are low heat units and the 48HGF
units are high heat units. The 50HG units are available with 3 sizes of electric heat or
as cooling only units. All units are intended for installation on an accessory curb
(ordered separately). Bottom discharge on concentric applications requires a transition duct (field-supplied) external to the unit.
