General Electric nam48e1ta4 Ecm Air Handler 4 Ton

Product Description

The GENERAL ELECTRIC nam48e1ta4 is a 4-ton, 1-piece air handling unit built for residential forced-air systems. It features an electronically commutated motor (ECM) for quieter, more energy-efficient operation compared to standard PSC motors. The coil assembly uses aluminum alloy tube and fin construction, and the unit ships with a factory-installed TXV for accurate refrigerant metering at the coil. At 176 pounds net weight and a gray cabinet finish, this AHU is sized for typical residential installations handled by licensed HVAC technicians. The factory-installed TXV eliminates a common field-installation step and helps ensure consistent system performance across a range of operating conditions.

The nam48e1ta4 is intended for residential split-system cooling and heat pump applications where a 4-ton indoor air handler is required. The 1-piece configuration simplifies placement in utility closets, attic platforms, garages, and mechanical rooms where clearance allows for the unit's overall dimensions of 55.75 inches tall, 21.5 inches wide, and 22 inches deep. Licensed HVAC contractors typically pair this unit with a matched outdoor condensing unit or heat pump to form a complete split system.

Installation Notes

Installation must be performed by a licensed HVAC technician in accordance with local mechanical codes and the manufacturer's installation instructions. Disconnect and lock out all electrical power before servicing or connecting the unit. Refrigerant line connections require proper brazing, leak testing, and system evacuation per EPA Section 608 requirements. Verify that the installation site provides adequate clearances on all sides as specified in the product installation manual before setting the unit.
