Trane M5THS2318A11NA Condensing Unit Heat Pump 1.5 Ton 208-230V Ductless Mini-split

Product Description

The Trane M5THS2318A11NA is an outdoor condensing unit designed for ductless mini-split heat pump systems. Operating on 208-230 volt single-phase power, this 1.5-ton unit handles both heating and cooling functions from an outdoor-mounted cabinet. Licensed HVAC technicians install this unit as part of a matched ductless system, connecting it to a compatible indoor air handler via refrigerant lineset and control wiring. The unit is part of the Ameristar 23U Series product line and is engineered for residential single-zone applications where traditional ducted systems are not practical or installed.

This condensing unit is suited for residential single-zone ductless installations, including room additions, converted garages, sunrooms, and other spaces requiring dedicated climate control without duct infrastructure. It pairs with a compatible indoor wall-mounted or ceiling-cassette air handler as part of a complete mini-split system. The Ameristar 23U Series designation indicates a matched-system application, and the unit should only be installed as part of a verified matched indoor-outdoor pair per manufacturer system ratings.

Key Features

• 1.5-ton capacity suited for single-zone residential ductless applications
• 208-230 volt operation compatible with standard residential electrical service
• Heat pump design provides both heating and cooling from a single outdoor unit
• Outdoor condensing unit configuration for standard pad or wall-bracket mounting
• Part of the Ameristar 23U Series matched ductless mini-split platform

Compatibility

This unit is part of the Ameristar 23U Series 2-ton class ductless mini-split platform. Install only with verified matched indoor air handler units per system rating documentation. Do not mix with unverified indoor units, as system performance and certification depend on matched-pair installation.

Installation Notes

Installation must be performed by a licensed HVAC technician holding an EPA Section 608 refrigerant handling certification. Before any service or connection work, shut off all electrical power to the circuit at the disconnect and at the main panel. Refrigerant lineset sizing, flaring, and evacuation procedures must follow the manufacturer installation manual and local mechanical code requirements. Refer to the unit nameplate and installation documentation for electrical disconnect sizing and minimum circuit ampacity before roughing in the circuit.
