It uses R-454B refrigerant, a lower-global-warming-potential alternative to R-410A, making it compliant with current EPA refrigerant transition requirements. This self-contained unit houses both the heating and cooling components in a single cabinet, eliminating the need for a separate indoor condensing section. It operates on 208\/230-volt, single-phase, 60 Hz power. Licensed HVAC technicians install this unit in rooftop or ground-level applications for residential and light commercial projects requiring integrated heating and cooling in one package.\u003c\/p\u003e\n\u003cp\u003eThe J5PH4048A1000A is suited for residential and light commercial applications where a fully self-contained system is preferred or required by the installation layout. Typical scenarios include slab-mounted installations on the exterior of a structure or rooftop placements using a roof curb adapter. The unit is designed to connect directly to the building ductwork through supply and return openings on the bottom or side of the cabinet, depending on the orientation selected at installation. This packaged format simplifies service access since all refrigerant components, the air handler section, and controls are located in one enclosure.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-ton (48,000 BTU\/h) capacity for year-round heating and cooling from a single unit\u003c\/li\u003e\n  \u003cli\u003e13.4 SEER2 efficiency rating meets current DOE minimum efficiency standards\u003c\/li\u003e\n  \u003cli\u003eR-454B refrigerant — lower GWP, EPA-compliant for new equipment regulations\u003c\/li\u003e\n  \u003cli\u003e208\/230-volt, single-phase, 60 Hz electrical configuration\u003c\/li\u003e\n  \u003cli\u003eAll-in-one packaged design simplifies installation where separate indoor and outdoor units are not practical\u003c\/li\u003e\n  \u003cli\u003eCompatible with optional electric heat kits for supplemental or emergency heat capacity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM packaged heat pump unit in the Oxbox J5PH4 product family.

Disconnect and lock out all electrical power before servicing any components. Ductwork connections, equipment sizing, and clearances must comply with local mechanical codes and the manufacturer installation manual. Do not use R-410A service equipment or recovery cylinders with R-454B refrigerant circuits.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCooling Capacity\u003c\/strong\u003e: 48,000 BTU\/h (4 tons)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSEER2 Rating\u003c\/strong\u003e: 13.4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRefrigerant Type\u003c\/strong\u003e: R-454B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 208\/230 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePhase\u003c\/strong\u003e: Single phase\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFrequency\u003c\/strong\u003e: 60 Hz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit Weight\u003c\/strong\u003e: 300 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: Oxbox\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: J5PH4048A1000A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OXBOX","offers":[{"title":"Default Title","offer_id":50962575393074,"sku":"J5PH4048A1000A","price":5905.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308797554.webp?v=1780589245","url":"https:\/\/voomisupply.com\/products\/oxbox-j5ph4048a1000a-heat-pump-unit-4-ton","provider":"Voomi Supply","version":"1.0","type":"link"}
