Branch headers distribute refrigerant from the main line to multiple indoor units, serving as a critical junction point in VRF piping networks. This component operates on a 24 VAC control signal in a single-phase configuration and is constructed with copper connections. It is sized for field installation by licensed HVAC technicians experienced in VRF system design and commissioning. The unit measures 18 inches in length, 9.7 inches in width, and 4.3 inches in height, making it a compact fit for typical VRF branch configurations.\u003c\/p\u003e\u003cp\u003eThis branch header is applied in residential and light commercial VRF heat pump installations where multiple indoor fan coil units or cassettes are served from a single refrigerant branch circuit. The 4-port configuration supports up to four connected indoor units from one header assembly. It is typically installed in concealed ceiling or mechanical room locations where VRF piping is routed and insulated per manufacturer and code requirements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-port design supports distribution to up to four indoor VRF units from a single branch point\u003c\/li\u003e\n\u003cli\u003eCopper construction for reliable, leak-resistant refrigerant connections\u003c\/li\u003e\n\u003cli\u003e24 VAC single-phase control voltage\u003c\/li\u003e\n\u003cli\u003eUL Listed and UL Recognized for compliance in commercial and residential installations\u003c\/li\u003e\n\u003cli\u003eCompact profile: 18 inches x 9.7 inches x 4.3 inches\u003c\/li\u003e\n\u003cli\u003eProp 65 compliant designation noted for California installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in Carrier and Bryant VRF heat pump systems.

Shut down and isolate the refrigerant circuit completely before connecting or disconnecting any branch header piping. All refrigerant piping work must comply with applicable local codes and manufacturer installation instructions. Piping joints at the header ports should be pressure-tested and leak-checked before system startup.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 24 VAC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhase\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Ports\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 18 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 9.7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 4.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 28.7 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApprovals\u003c\/strong\u003e: UL Listed, UL Recognized\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: China\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CARRIER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 40vm900025\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARRIER","offers":[{"title":"Default Title","offer_id":51138459730226,"sku":"40VM900025","price":450.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305533120.webp?v=1778257074","url":"https:\/\/voomisupply.com\/products\/carrier-40vm900025-branch-header-heat-pump-vrf-4-port","provider":"Voomi Supply","version":"1.0","type":"link"}
