Rheem 3 Ton R-454B Commercial Packaged Air Conditioner — RACCYB036ADT000AAAA0
The Rheem RACCYB036ADT000AAAA0 delivers the same 3-ton, 34,200 BTU/h Commercial Classic Series cooling platform but is built for 460V three-phase power, the standard distribution voltage in many schools, warehouses, and larger commercial buildings. Factory-charged with R-454B and rated at 10.6 EER2 / 13.4 SEER2, it uses a single-stage scroll compressor, microchannel coils, and convertible downflow or horizontal supply so a single compact rooftop unit can condition a small tenant space, server closet make-up zone, or modular classroom fed from a 460V panel.
Is a 3-Ton Package Unit the Right Size?
This 3-ton unit sits near the entry of Rheem's small-commercial RACC line and is matched to spaces with a cooling load in the neighborhood of 34,000 to 36,000 BTU/h — often roughly 1,200 to 1,800 sq ft of conditioned light-commercial space, depending on the building. Square footage alone is only a starting point, though; two rooms of the same size can carry very different loads.
Insulation levels, roof and wall exposure, ceiling height, the number of people in the space, lighting and plug loads, outdoor design temperature, and ventilation air all change the calculated load. A sun-exposed corner suite with lots of glass and foot traffic can need this full 3 tons where a shaded, well-insulated back office of the same size would not. Sizing from a Manual N / Manual J style load calculation rather than area alone keeps the compressor off short cycles and protects comfort and humidity control.
Ideal for: Small tenant spaces, offices, classrooms, and equipment rooms located in schools, warehouses, and larger commercial or industrial buildings that distribute power at 460V three-phase.
Need more capacity? Step up to the 4-Ton Rheem R-454B 460V 3-Phase Package Unit (RACCYB048ADT000AAAA0) for larger zones that need more cooling capacity.
Recommended applications are general guidelines only. Actual capacity requirements depend on insulation, ventilation, occupancy, solar gain, ceiling height, and local design temperatures. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.

The RACCYB036ADT000AAAA0 ships as one factory-assembled, wired, and run-tested cabinet, so there is no field refrigerant line set to braze — it arrives charged with R-454B and ready to set, connect power and ducting, and commission. For curbed rooftop installs, pair it with the matching 3–6 Ton Rheem 14 in. roof curb (RXKG-DCC14).

Frequently Asked Questions
What size space will the RACCYB036ADT000AAAA0 cool?
It is matched to commercial cooling loads around 36,000 BTU/h (34,200 BTU/h AHRI net), which often lands near roughly 1,200 to 1,800 sq ft of light-commercial space. Because occupancy, ventilation, glazing, and internal heat gain move the real load, confirm the size with a commercial load calculation rather than floor area alone.
Why choose the 460V RACCYB036ADT000AAAA0 over the 208/230V model?
On 460V, 3-Phase, 60 Hz this unit draws about half the amperage of the 208/230V build — a 10 A minimum circuit ampacity and 15 A maximum overcurrent protection, with a compressor RLA of 5.1 A. That eases wiring and breaker sizing where a 460V service feeds several units. If your panel is 208/230V, order the 208/230V three-phase 3-ton version instead.
Is this unit charged with R-454B, and does it have leak detection?
Yes. The RACCYB036ADT000AAAA0 is factory-charged with low-GWP R-454B (an A2L refrigerant) and includes a factory-installed refrigerant leak detection system that triggers a fault and mitigation sequence if a leak is sensed. Refrigerant charge is approximately 72 oz.
Can this package unit be installed downflow and horizontal?
Yes. Airflow is field-convertible between vertical downflow (for roof-curb installations) and horizontal side-flow, so the same unit works on a curbed rooftop opening or a slab with ducted side connections. A matching 14 in. Rheem roof curb (RXKG-DCC14) is available for 3–6 ton units.
Does this unit provide heat?
This is a cooling-only (straight-air) package air conditioner. Electric resistance heater kits are available as field- or factory-installed accessories on the RACC platform; if you need heating built in, a gas/electric or heat-pump package unit is the better starting point.
Does the RACC package unit include a warranty?
Yes. Rheem provides a limited warranty on the RACC series — a 5-year compressor and 1-year parts limited warranty for commercial applications (longer terms may apply to residential applications on 3–5 ton models with registration). See the Rheem Limited Warranty document above for full terms and conditions.
