48GS(N)/48GX(N) units are self-contained, gas heating/electric cooling
units designed for easy installation and maintenance and dependable per-
formance. All units have discharge openings for either horizontal or
downflow configuration, and all have low sound levels. Units are intend-
ed for outdoor installation and may be located on a rooftop, or a ground-
level concrete slab, or directly on the ground if local codes permit.
