This unit is part of ICP's entry-level heat pump lineup, providing both heating and cooling in a single outdoor condensing package. A licensed HVAC technician handles installation, charging, and commissioning. The R454B refrigerant classification requires A2L-compliant service practices and certified equipment, so field technicians should confirm their tooling and training meet current requirements before starting work.\u003c\/p\u003e\n\u003cp\u003eThe PHB436000K000B is suited for residential split-system applications where a 3-ton capacity matches the calculated heating and cooling load. It pairs with a compatible indoor air handler or furnace coil and is intended for entry-level replacement or new-construction installs where straightforward single-stage operation is the design goal. Verify system static, refrigerant line sizing, and electrical service before finalizing the installation plan.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-ton nominal capacity for residential split-system heat pump applications\u003c\/li\u003e\n  \u003cli\u003eR454B refrigerant compliance meets current EPA low-GWP phasedown requirements\u003c\/li\u003e\n  \u003cli\u003eEntry-level single-stage operation simplifies controls integration and service\u003c\/li\u003e\n  \u003cli\u003eOutdoor condensing unit configuration for standard split-system installs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style entry-level outdoor heat pump unit for use in residential split-system configurations requiring 3-ton capacity and R454B refrigerant compatibility.

Disconnect and lock out all electrical power to the system before making any wiring or refrigerant connections. Follow NEC requirements for disconnect sizing and wire gauge, and adhere to local mechanical codes for pad placement, clearances, and line set routing. Do not attempt to substitute R454B with any other refrigerant, as the system components are designed and rated for this specific refrigerant blend.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Capacity\u003c\/strong\u003e: 3 tons\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRefrigerant Type\u003c\/strong\u003e: R454B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions (L x W x H)\u003c\/strong\u003e: 18.375 inches\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: ICP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: PHB436000K000B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ICP","offers":[{"title":"Default Title","offer_id":51506582946098,"sku":"PHB436000K000B","price":8456.5,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/PHB5_1_500x500_cb942ac6-059d-467f-9e3d-d5c34485a17f.jpg?v=1784926278","url":"https:\/\/voomisupply.com\/products\/icp-phb436000k000b-3-ton-r454b-heat-pump","provider":"Voomi Supply","version":"1.0","type":"link"}
