Rated at 3 to 3.5 tons, it pairs an electronically commutated motor (ECM) blower with an integrated control board to deliver efficient, quiet airflow management. The unit ships in a standard 230-volt single-phase configuration and includes a built-in anti-frost control, float switch, and condensate trap. A slide-out blower assembly simplifies field servicing, and motor staging is adjustable without additional components. Licensed HVAC technicians install this unit as the indoor air-handling section of a split heat pump system.\u003c\/p\u003e\u003cp\u003eThe ESP3642JH4M is intended for single-phase, single-stage heat pump split systems where a high-velocity air distribution design is required. At 3 to 3.5 tons, it fits a common range of residential and smaller commercial load calculations. The unit is field-convertible to 115 volts for installations where 230-volt service is not available, expanding placement flexibility. Its compact cabinet dimensions of 29.375 inches deep, 33.25 inches wide, and 14.12 inches tall allow installation in tight mechanical spaces such as closets, attics, and utility rooms.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHigh-efficiency ECM blower motor reduces energy draw and operating noise compared to PSC motor designs\u003c\/li\u003e\n\u003cli\u003eEasy field-adjustable motor staging allows airflow customization without additional parts\u003c\/li\u003e\n\u003cli\u003eSlide-out blower assembly improves access for maintenance and coil cleaning\u003c\/li\u003e\n\u003cli\u003eStandard 230-volt configuration with optional field conversion to 115 volts\u003c\/li\u003e\n\u003cli\u003eIntegrated anti-frost control protects the coil during low-load or low-ambient conditions\u003c\/li\u003e\n\u003cli\u003eFloat switch and condensate trap included for moisture management and overflow protection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fan coil for high-velocity heat pump split systems in the 3 to 3.5 ton capacity range, single-phase configuration.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician in accordance with local mechanical codes and the manufacturer instructions. Disconnect and lock out all electrical power before making any wiring connections or performing coil work. Refrigerant line connections require an EPA Section 608 certified technician; the 3\/8-inch liquid line and 7\/8-inch suction fitting must be properly brazed and leak-checked before system startup. Verify that the condensate drain is properly pitched and that the float switch circuit is functional before energizing the unit.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Capacity\u003c\/strong\u003e: 3 to 3.5 tons\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAir Handler Type\u003c\/strong\u003e: High Velocity\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 230 volts (standard); 115 volts (optional field conversion)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhase\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStages\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLiquid Line Connection\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuction Line Connection\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDepth\u003c\/strong\u003e: 29.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 33.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 14.12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 123 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SPACEPAK\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ESP3642JH4M\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPACEPAK","offers":[{"title":"Default Title","offer_id":51283907608882,"sku":"ESP3642JH4M","price":4076.46,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277725.jpg?v=1781062969","url":"https:\/\/voomisupply.com\/products\/spacepak-esp3642jh4m-air-handler-fan-coil-3-5-ton","provider":"Voomi Supply","version":"1.0","type":"link"}
