Trane M5THS2324A11NA Split System Heat Pump 24000 Btu R-454B Refrigerant

Product Description

The Trane M5THS2324A11NA is a residential split system heat pump outdoor unit designed for whole-home cooling and heating applications. Operating on R-454B refrigerant, this unit reflects Trane's shift toward lower global-warming-potential refrigerant technology in compliance with current environmental standards. Rated at approximately 24,000 BTU, it is sized for a 2-ton application and is intended for installation by a licensed HVAC technician as part of a matched split system. The M5THS2324A11NA is built for standard residential pad or slab mounting and connects to a compatible indoor air handler or coil to complete the system.

This unit is suited for residential single-family and light multi-family installations where a 2-ton cooling and heating capacity meets the load requirement. It is designed for use in split system configurations where the outdoor condensing section is paired with an indoor evaporator coil or air handler. Typical installations involve replacement of an aging outdoor unit or as part of a new system build-out in residential construction. Licensed HVAC contractors performing equipment changeouts or new installs are the primary installers of this unit.

Disconnect and lock out all electrical power to the system before making any refrigerant or electrical connections. The unit should be mounted on a level concrete pad or approved equipment base per manufacturer guidelines and local mechanical codes. Do not operate the system without verifying proper refrigerant charge and system static pressures using calibrated gauges.
