Carrier EA36UZ116 Txv Replacement

Product Description

The CARRIER EA36UZ116 is a thermostatic expansion valve (TXV) designed for use in packaged rooftop HVAC units. The TXV meters refrigerant flow into the evaporator coil, responding to suction line superheat to maintain proper refrigerant feed under varying load conditions. This direct control of refrigerant flow protects the compressor from liquid slugging and helps maintain system efficiency. At 1 pound, it is a compact component that fits within the refrigerant circuit of the systems listed below. Installation and replacement are typically performed by licensed HVAC technicians familiar with refrigerant handling and EPA Section 608 requirements.

The EA36UZ116 TXV is used in Carrier packaged rooftop units across a range of model numbers in the 48HG and 48HJ series. These are commercial-style packaged gas/electric or cooling-only rooftop units commonly found in light commercial applications. The valve serves as a critical refrigerant metering component within the system refrigerant circuit. Refer to the compatible model list for verified fitment before ordering to confirm this valve matches the existing refrigerant circuit configuration of the unit being serviced.

Installation Notes

TXV replacement must be performed by an EPA Section 608 certified HVAC technician. Recover all refrigerant from the system before opening the refrigerant circuit. Ensure the system is fully de-energized and pressure is relieved before removing the existing valve. After installation, leak-test all connections and recharge the system to manufacturer specifications before returning the unit to service.
