Trane M5THS2309A11NA Ductless Heat Pump Outdoor Unit 9000 Btu/h 23 SEER2 R-454B

Product Description

The Trane M5THS2309A11NA is a 9,000 BTU/h ductless mini-split heat pump outdoor condenser unit rated at 23 SEER2 and designed to operate on R-454B refrigerant. Part of the Trane 23 Series ductless lineup, this unit delivers both heating and cooling from a single outdoor condenser, handling cooling operation down to 5 degrees F ambient and heating operation down to -13 degrees F. The unit runs on 230-volt power with a 15-amp fuse rating and uses a 1/4-inch liquid line and 3/8-inch gas line for the 9K configuration. Licensed HVAC technicians install and commission this equipment as part of a matched ductless split system.

The M5THS2309A11NA is suited for residential single-zone applications where ductwork is not available or practical, such as room additions, converted spaces, sunrooms, and individual zone control applications. The 23 SEER2 efficiency rating qualifies this unit under current Energy Star program criteria for ductless products. It pairs with a compatible Trane or American Standard 23 Series indoor air handler to form a complete matched system. The R-454B refrigerant charge makes this unit compliant with current low-GWP refrigerant requirements in applicable jurisdictions.

Compatibility

Designed for use as part of a matched Trane or American Standard 23 Series ductless split system. This outdoor unit must be paired with a compatible 23 Series indoor air handler. Consult the Trane 23 Series ductless submittal documentation for approved matched indoor unit combinations.

Installation Notes

Installation must be performed by a licensed HVAC technician certified to handle A2L refrigerants, as R-454B is a mildly flammable refrigerant class requiring specific handling procedures and leak detection practices. Shut off all electrical power to the system at the disconnect before making line set or electrical connections. Connecting cable size for the 9K 230-volt configuration is 16 AWG per Trane installation documentation. Follow all applicable local mechanical and electrical codes, including NEC requirements for disconnect sizing and line set installation clearances.
