Carrier 40vm900025 Branch Header Heat Pump Vrf 4 Port

Product Description

The CARRIER 40vm900025 is a 4-port branch header designed for use in variable refrigerant flow (VRF) heat pump systems. 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.

This 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.

Compatibility

Designed for use in Carrier and Bryant VRF heat pump systems. Verify system piping design and branch header selection with the applicable Carrier VRF engineering guide before installation.

Installation Notes

Installation should be performed by a licensed HVAC technician with experience in VRF refrigerant piping 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.
