Oxbox J5PH4042A1000A Packaged Heat Pump Unit 3.5 Ton 13.4 SEER2 R-454B Refrigerant Single Phase

Product Description

The Oxbox J5PH4042A1000A is a 3.5-ton packaged heat pump unit engineered for year-round residential and light commercial heating and cooling. Factory-assembled in an all-in-one outdoor enclosure, it eliminates the need for a separate indoor coil or air handler, simplifying system layout and reducing installation time. The unit operates on 208/230-volt single-phase, 60 Hz power and carries a 13.4 SEER2 efficiency rating, meeting current DOE minimum efficiency standards. It runs on R-454B refrigerant, a lower global-warming-potential alternative to legacy refrigerants. Licensed HVAC technicians handle installation and service.

The J5PH4042A1000A is suited for rooftop or ground-level pad installations in residential homes and light commercial buildings that require a single outdoor package rather than a split system. Its all-in-one design houses the compressor, refrigerant coil, and indoor fan section in one cabinet, which makes it a practical choice for structures with limited interior mechanical space. The unit is available as part of the Oxbox J5PH4 series, which spans 2- to 5-ton capacities, allowing for scalable system design across multiple project types.

Key Features

• 3.5-ton cooling and heating capacity covers typical residential and light commercial loads
• 13.4 SEER2 efficiency rating meets current federal minimum efficiency requirements
• R-454B refrigerant with lower global-warming potential compared to R-410A
• 208/230-volt single-phase power for straightforward integration with standard electrical service
• Factory-engineered all-in-one outdoor package simplifies installation and system design
• High-efficiency outdoor coil optimized for effective heat transfer across heating and cooling seasons

Compatibility

The J5PH4042A1000A is part of the Oxbox J5PH4 packaged heat pump series, which covers 2- to 5-ton capacities. Confirm electrical service, duct static pressure, and local code requirements before installation to ensure proper system compatibility.

Installation Notes

Installation must be performed by a licensed HVAC technician in accordance with local mechanical codes and the manufacturer installation manual. Disconnect and lock out all electrical power before servicing or making electrical connections. The unit requires a dedicated branch circuit sized to the minimum circuit ampacity listed on the unit nameplate. Verify that the installation site provides adequate clearance on all sides per the installation manual and that the refrigerant line connections and electrical conduit entries are properly sealed against weather intrusion.
