Ruud RHPBYB048AJT000NA M1 Packaged Heat Pump 4 Ton 13.4 SEER2

Product Description

The RUUD RHPBYB048AJT000NA is a 4-ton horizontal packaged heat pump from the M1 Series, rated at 13.4 SEER2 for seasonal energy efficiency. This self-contained unit combines heating and cooling functions in a single cabinet, making it a straightforward replacement or new-installation option for applications where indoor mechanical space is limited or unavailable. The unit operates on R454B refrigerant, a lower-GWP alternative that aligns with current EPA refrigerant transition requirements. Licensed HVAC technicians handle installation and commissioning of this equipment.

The RHPBYB048AJT000NA is configured for horizontal orientation, which suits rooftop curb applications, crawlspace setups, and side-discharge installations common in light commercial and residential construction. At 48,000 BTU/h nominal capacity, this unit is sized for medium-to-large residential spaces or light commercial zones requiring a single packaged solution. The M1 Series is designed for straightforward field installation with standard duct connections.

Key Features

• 4-ton (48,000 BTU/h) nominal cooling and heating capacity
• 13.4 SEER2 efficiency rating meeting current federal minimum standards
• Horizontal orientation for rooftop, crawlspace, or side-discharge installations
• R454B refrigerant — lower global warming potential versus legacy R410A
• All-in-one packaged design eliminates the need for a separate indoor air handler

Compatibility

Designed as an OEM packaged heat pump unit within the RUUD M1 Series horizontal product line. Consult the unit submittal sheet and installation manual for compatible thermostat controls, duct configurations, and curb adapter specifications before ordering.

Installation Notes

Installation must be performed by an EPA Section 608 certified HVAC technician licensed in the jurisdiction of the job site. Disconnect and lock out all electrical power before any service or installation work on the unit. R454B is an A2L mildly flammable refrigerant — follow current ASHRAE 15 and local mechanical code requirements for handling, leak detection, and ventilation in the equipment room or rooftop area. Verify duct static pressure requirements and electrical supply voltage and ampacity against the unit nameplate before final connection.
