First Company 9evr32-1a R-32 Txv Kit Hxs Series

Product Description

The FIRST COMPANY 9evr32-1a is an R-32 refrigerant TXV (thermostatic expansion valve) kit designed for use with First Company HX, CDX, and UC series air handlers in the 18,000 to 37,000 BTU/h range. The TXV meters refrigerant flow into the evaporator coil, maintaining proper superheat and protecting the compressor under varying load conditions. This kit is intended for ceiling-mount fire-down configurations and is supplied as an OEM-style replacement or field-install accessory. Licensed HVAC technicians handle this component as part of a refrigerant-side service or system commissioning procedure.

This TXV kit is applicable to First Company HX, CDX, and UC series ceiling-mount air handlers sized 18 through 37. It supports R-32 refrigerant systems, which operate at higher pressures than legacy R-410A equipment. The fire-down orientation references the coil and valve positioning in ceiling-mount installations where supply air discharges downward. This makes it a common service part for commercial and light commercial split systems using First Company fan coil equipment in plenum or above-ceiling applications.

Compatibility

Compatible with First Company HX, CDX, and UC series ceiling-mount air handlers in the 18 through 37 size range using R-32 refrigerant.

Installation Notes

Installation must be performed by an EPA Section 608 certified HVAC technician authorized to handle R-32 refrigerant. Recover all refrigerant and recover system pressure before opening the refrigerant circuit. R-32 is a mildly flammable (A2L) refrigerant — follow applicable local codes and the manufacturer's safety guidelines for A2L handling during service. Confirm valve orientation and flow direction before brazing or connecting fittings, and leak-test all joints before recharging the system.
