Oxbox J5HP5048A1000 Heat Pump Condenser 4 Ton 48000 Btu 14.3 SEER2 R-454B Residential Split System

Product Description

The Oxbox J5HP5048A1000 is a 4-ton, 48000 BTU/h outdoor heat pump condenser rated at 14.3 SEER2, designed for residential split-system heating and cooling. It operates on R-454B refrigerant, a lower-GWP alternative to R-410A, and runs on a 208/230-volt, single-phase, 60 Hz power supply. The unit carries a minimum branch circuit ampacity of 28 amps. Licensed HVAC technicians install this condenser as the outdoor half of a ducted split system, pairing it with a compatible indoor air handler to deliver both cooling and heat pump heating in mild to moderate climates.

This condenser is suited for residential applications where a ducted split-system heat pump is the specified equipment. It is paired with an indoor air handler to form a complete heating and cooling system. Heat pump systems of this type are commonly specified for mild-climate regions where supplemental electric heat can cover heating demand without a gas furnace. The unit is sold as the outdoor condenser only; a matched air handler is required to complete the system installation and meet rated efficiency.

Key Features

• 4-ton (48000 BTU/h) cooling and heat pump heating capacity
• 14.3 SEER2 efficiency rating, meeting current DOE minimum efficiency standards
• R-454B refrigerant — lower global warming potential than R-410A
• 208/230-volt, single-phase, 60 Hz operation
• 28-amp minimum branch circuit ampacity
• Painted, galvanized steel cabinet construction for corrosion resistance

Compatibility

Designed for use in residential ducted split-system installations. Web evidence indicates compatibility with the J5AH4P48A1C00AA indoor air handler to form a matched 4-ton, 14.3 SEER2 system. Confirm matched system combinations with the equipment submittal or Oxbox product documentation before installation to ensure rated efficiency is achieved.

Installation Notes

Installation must be performed by a licensed HVAC technician holding the appropriate EPA Section 608 certification for handling refrigerants. Disconnect and lock out all high-voltage power before servicing the unit. The refrigerant circuit must be leak-checked and fully evacuated before charging with R-454B. Low-voltage control wiring and high-voltage power supply connections must comply with the National Electrical Code and all applicable local codes.
