Gree FLEXA2LHTR06KW 6kW Electric Resistance Auxiliary Heater Kit for FLEXX Ultra R32 (FXU Series) Central Air Handlers – 208/240V, 1-Phase, 60Hz
<p><span style="color: rgb(0, 0, 0);">A factory-engineered, field-installed electric resistance backup heat kit purpose-built for integration into Gree's FLEXX Ultra R32 inverter heat pump platform (FXU series ducted air handlers). This 6-kilowatt heater module installs directly into the air handler's dedicated electric heat cavity, delivering supplemental and emergency-mode heating output to maintain conditioned-space comfort when outdoor ambient temperatures drop below the inverter heat pump's balance point or when the system enters its defrost cycle. The assembly is constructed around durable nichrome resistance heating elements paired with a high-limit thermal cutout for over-temperature protection and a sequenced contactor arrangement that staggers element energization to limit inrush current and reduce demand stress on the home's electrical service. Engineered as a true OEM-matched accessory, the FLEXA2LHTR06KW is wired directly into the FXU air handler's onboard 24VAC control logic, allowing the inverter heat pump's primary control board to call for and stage auxiliary heat automatically without additional thermostat reconfiguration. As the lowest-output member of the FLEXA2L heater kit family, this 6 kW kit is the standard specification for smaller-tonnage FLEXX Ultra installations, milder-climate applications, and homes with limited service-panel capacity where a higher-output 9, 12, or 15 kW kit would exceed available electrical headroom. The unit ships ready for field installation by a qualified HVAC technician with the cover plate and integrated breaker hardware required for safe, code-compliant integration.</span></p>

| value | rgb(0, 0, 0);">Electric resistance auxiliary heater kit rated at 6 kW nominal output, designed exclusively for installation inside the Gree FLEXX Ultra R32 (FXU series) central air handler. Operates on a 208/240V, 1-Phase, 60 Hz dedicated power circuit, with rated output of 6 kW at 240V and a proportionally lower output of approximately 4.5 kW at 208V (per Gree's standard FLEXX heater output curve). Manufacturer SKU: FLEXA2LHTR06KW. Compatible with the Gree FLEXX Ultra R32 FXU air handler line — confirmed compatibility with FXU24HP230V1R32AH (2-ton), FXU36HP230V1R32AH (3-ton), FXU48HP230V1R32AH (4-ton), and FXU60HP230V1R32AH (5-ton) indoor units; not for use with the legacy FLEXX (R410A) FLEXX24/36/60HP series, which require the FLEXXHTR-series heater kits instead. Kit includes the resistance element assembly, mounting hardware, integrated factory contactor/relay assembly with staged element sequencing, high-temperature thermal limit cutout for over-temperature protection, cover plate, and integrated circuit breaker for code-compliant overcurrent protection. Wiring integrates with the air handler's onboard 24VAC control circuit, allowing the FLEXX Ultra inverter control logic to stage auxiliary heat automatically based on call-for-heat demand and outdoor balance-point conditions. Power wiring must be sized per applicable national and local electrical codes; the heater kit requires its own dedicated branch circuit separate from the indoor unit's primary power feed. Part of the FLEXA2L heater kit family which also includes the 9 kW FLEXA2LHTR09KW, 12 kW FLEXA2LHTR12KW, and 15 kW FLEXA2LHTR15KW variants, allowing installers to size the auxiliary heat output to the building load and electrical service capacity. Refrigerant compatibility: designed for FLEXX Ultra R32-refrigerant air handlers only. Installation must be performed by a qualified HVAC technician with all power to the system disconnected at the main electrical panel prior to opening the air handler.</span></p> |
