The GE Universal Fit 8.5-ton packaged electric/electric rooftop unit (catalog GC923, chassis ZCD102S5TN) is a standard-efficiency light commercial RTU for all-electric cooling with optional electric heat. It is built for contractor replacement and new-install jobs where gas heat is not required.

Configured for 208/230V, 3-phase power, this unit ships as a complete packaged rooftop with a 2 HP blower (1 drive). Universal Fit footprint support is intended to simplify curb matching on common commercial replacements and reduce downtime on the roof.

The cabinet uses heavy-gauge construction with full-perimeter base rails for rigging and handling. Service access panels, filter access, and factory refrigerant charge (R-454B with refrigerant detection system on current Universal Fit packaged models) are designed for straightforward startup and maintenance. Field accessories such as economizers, outdoor-air dampers, electric heat kits, and curbs must match B-BOX cabinet sizing — confirm accessory kits before quoting.
