Operating at a single-stage compression cycle, this outdoor condensing unit provides both heating and cooling to a connected air handler or furnace coil system. At 169 pounds, this is a substantial piece of outdoor equipment requiring proper slab or bracket mounting and adequate line-set sizing for R-454B service. Licensed HVAC technicians with A2L refrigerant certification handle installation and commissioning of this unit.\u003c\/p\u003e\n\u003cp\u003eThe MR5H5S18AKAAA is intended for residential split-system heat pump applications. The R-454B refrigerant classification as an A2L mildly flammable refrigerant requires installers to follow updated safety protocols and use equipment rated for A2L service. This unit suits new-construction and replacement installations where the system is matched to a compatible air handler or furnace coil. The 1-stage compressor design provides straightforward operation and simplified controls integration for standard residential thermostat configurations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e15 SEER2 efficiency rating meets current DOE regional efficiency minimums for residential heat pumps\u003c\/li\u003e\n  \u003cli\u003eR-454B refrigerant with significantly lower global warming potential compared to legacy R-410A systems\u003c\/li\u003e\n  \u003cli\u003eSingle-stage compressor operation for reliable, straightforward heating and cooling performance\u003c\/li\u003e\n  \u003cli\u003eMaratherm product line under the ICP manufacturing umbrella for broad parts and service support\u003c\/li\u003e\n  \u003cli\u003eUnit weight of 169 pounds requires appropriate structural mounting and two-person installation practice\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style residential split-system heat pump outdoor unit.

Disconnect all electrical power at the service disconnect and verify zero voltage before any wiring or refrigerant work. R-454B is classified A2L and requires A2L-rated recovery equipment, manifold gauges, and leak detection tools. Follow local mechanical and electrical codes, including NEC Article 440 for hermetic refrigerant motor-compressor circuits, for all electrical connections and overcurrent protection sizing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRefrigerant\u003c\/strong\u003e: R-454B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSEER2 Rating\u003c\/strong\u003e: 15\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompressor Stages\u003c\/strong\u003e: 1-Stage\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Heat Pump\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 169 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: INTERNATIONAL COMFORT PRODUCTS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MR5H5S18AKAAA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"INTERNATIONAL COMFORT PRODUCTS","offers":[{"title":"Default Title","offer_id":51306714005810,"sku":"MR5H5S18AKAAA","price":2580.54,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309549212.jpg?v=1781296121","url":"https:\/\/voomisupply.com\/products\/icp-mr5h5s18akaaa-maratherm-heat-pump-15-seer2-r-454b","provider":"Voomi Supply","version":"1.0","type":"link"}
