It delivers 12,000 BTU\/h of cooling capacity and 15,000 BTU\/h of heating capacity through an inverter-driven ECM fan motor that maintains constant airflow regardless of external static pressure. The unit supports hot start operation, soft dry mode, auto operation, auto restart, and a programmable on\/off\/weekly timer. An integrated R-32 leak detection sensor and built-in dry contact for third-party thermostat integration make this a flexible choice for residential and light commercial HVAC applications.\u003c\/p\u003e\n\u003cp\u003eThis air handler is intended for multi-zone systems where each zone requires an independently controlled indoor unit. Its multi-position design allows installation in multiple orientations to accommodate a range of residential and light commercial spaces. Licensed HVAC technicians performing multi-zone mini-split retrofits or new construction installs will find the integrated dry contact particularly useful when a building automation system or conventional thermostat is already in place. The ECM fan motor sustains airflow between 420 and 500 CFM across varying system conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInverter-driven ECM fan motor delivers constant airflow regardless of external static pressure\u003c\/li\u003e\n  \u003cli\u003e12,000 BTU\/h cooling capacity and 15,000 BTU\/h heating capacity\u003c\/li\u003e\n  \u003cli\u003eR-32 refrigerant compatible with integrated leak detection sensor\u003c\/li\u003e\n  \u003cli\u003eBuilt-in dry contact for third-party thermostat or BAS integration\u003c\/li\u003e\n  \u003cli\u003eMulti-position installation design for flexible mounting configurations\u003c\/li\u003e\n  \u003cli\u003eHot start, soft dry, auto restart, sleep mode, and programmable weekly timer included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in LG Multi F multi-zone ductless systems using R-32 refrigerant. Consult the outdoor unit compatibility documentation to confirm matched system pairings before installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a licensed HVAC technician in accordance with local mechanical codes and the manufacturer installation manual. Shut down and lock out the outdoor unit and disconnect all power before connecting refrigerant lines or low-voltage wiring. R-32 is an A2L mildly flammable refrigerant — follow applicable safety standards and local jurisdiction requirements for handling and leak testing. Verify airflow direction, drain line slope, and condensate routing before startup.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCooling Capacity\u003c\/strong\u003e: 12,000 BTU\/h\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeating Capacity\u003c\/strong\u003e: 15,000 BTU\/h\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRefrigerant Type\u003c\/strong\u003e: R-32\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Airflow\u003c\/strong\u003e: 500 CFM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Airflow\u003c\/strong\u003e: 420 CFM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Indoor Air Handler Unit\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFan Motor Type\u003c\/strong\u003e: ECM (Electronically Commutated Motor)\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: LG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: KNMLB121A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LG","offers":[{"title":"Default Title","offer_id":51345388601650,"sku":"KNMLB121A","price":3379.53,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310555380.jpg?v=1782056746","url":"https:\/\/voomisupply.com\/products\/lg-knmlb121a-multi-zone-air-handler-12000-btu-h-indoor","provider":"Voomi Supply","version":"1.0","type":"link"}
