It functions as the indoor air handler in a split-system configuration, circulating conditioned air through connected ductwork while managing both heating and cooling. The unit incorporates a hot start function that delays fan operation until the heat exchanger reaches an adequate temperature, preventing cold drafts during heating startup. An internal condensate lift mechanism handles drainage without an external pump, lifting condensate up to 21.6875 inches. Licensed HVAC technicians handle installation and service of this equipment.\u003c\/p\u003e\u003cp\u003eThis air handler is designed for residential and light commercial ceiling-mounted applications where low-profile ductwork integration is required. It is well suited for spaces where a concealed installation is preferred over a wall-mounted or cassette-style unit. The unit supports dry mode operation, during which the coil temperature is maintained just below the dew point of return air to remove excess moisture without overcooling the space. This makes it appropriate for humid climates or applications where humidity control is a priority alongside temperature management.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHot start technology delays fan operation until the heat exchanger warms up, preventing cold drafts in heating mode\u003c\/li\u003e\n\u003cli\u003eDry mode holds coil temperature just below the dew point of return air for effective dehumidification without overcooling\u003c\/li\u003e\n\u003cli\u003eInternal condensate lift mechanism capable of raising condensate up to 21.6875 inches, eliminating the need for a separate condensate pump in many installations\u003c\/li\u003e\n\u003cli\u003eCeiling-mounted horizontal orientation integrates with low static ductwork for a concealed installation\u003c\/li\u003e\n\u003cli\u003e15,000 BTU\/h capacity suitable for residential and light commercial zones\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM indoor unit for use with compatible SZ and MZ series outdoor condensing units in Mitsubishi Electric mini-split heat pump systems.

Power down and lock out all electrical circuits before servicing the unit or making refrigerant connections. Ensure the ceiling structure can support the weight and dimensions of the unit and that ductwork static pressure requirements are within the rated operating range of this low static unit. Condensate drain lines should be pitched and routed per local plumbing and mechanical codes to prevent overflow.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacity\u003c\/strong\u003e: 15,000 BTU\/h\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Type\u003c\/strong\u003e: Indoor Ceiling Mounted Air Handler\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 7.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDepth\u003c\/strong\u003e: 27.5625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax Condensate Lift\u003c\/strong\u003e: 21.6875 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MITSUBISHI ELECTRIC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SEZ-KD15NA4R1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITSUBISHI ELECTRIC","offers":[{"title":"Default Title","offer_id":51284120469810,"sku":"SEZ-KD15NA4R1","price":1690.56,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309278813.png?v=1781069021","url":"https:\/\/voomisupply.com\/products\/mitsubishi-electric-sez-kd15na4r1-ducted-indoor-unit-15000-btu","provider":"Voomi Supply","version":"1.0","type":"link"}
