Trane WHC036H4REB64P0 Rooftop Heat Pump 3 Ton 460V 3-phase

Product Description

The TRANE WHC036H4REB64P0 is a commercial packaged rooftop heat pump from the Precedent series, rated at 3 tons and configured for 460-volt, three-phase electrical service. This self-contained unit handles both heating and cooling from a single rooftop-mounted cabinet, using R-410A refrigerant. It is engineered for light commercial applications where a single piece of equipment must deliver full HVAC functionality without separate indoor and outdoor components. Licensed commercial HVAC technicians handle procurement and installation of this class of equipment.

The WHC036H4REB64P0 is suited for light commercial rooftop installations such as retail buildings, small office spaces, and similar single-story structures. The three-phase 460-volt electrical configuration targets facilities with commercial power distribution rather than residential single-phase service. As part of the Precedent series, the unit is designed for curb-mount installation on standard commercial rooftop curbs, integrating with existing ductwork through the unit base. The R-410A refrigerant circuit meets current environmental standards for chlorine-free refrigerants in commercial cooling and heat pump applications.

Installation Notes

Installation must be performed by a licensed commercial HVAC technician familiar with rooftop packaged equipment. Disconnect and lock out all electrical power at the building disconnect before beginning any service or installation work. The unit requires a properly rated rooftop curb and structural support capable of bearing the equipment load. Refrigerant handling must comply with EPA Section 608 regulations, and all electrical work must conform to the NEC and applicable local codes.
