Trane YSJ120A4S0H122L Packaged Gas Electric Rooftop Unit

Product Description

The TRANE YSJ120A4S0H122L is a 10-ton packaged gas/electric rooftop unit built for commercial HVAC applications that require combined heating and cooling in a single self-contained cabinet. This unit operates on 460 volts, 3-phase power and is configured as a high-heat gas pack. It delivers both heating and mechanical cooling from one rooftop-mounted assembly, reducing the need for separate indoor air handlers or furnaces. Licensed commercial HVAC technicians and mechanical contractors are the primary installers for this class of equipment.

The YSJ120A4S0H122L is suited for light commercial and commercial rooftop installations such as retail buildings, office spaces, schools, and warehouses where a single packaged unit can serve a defined zone or the entire structure. The gas/electric configuration means natural gas or propane handles the heating load while the refrigerant circuit handles cooling, all within the same cabinet footprint. The 3-phase electrical supply requirement places this unit in commercial construction contexts rather than standard residential service.

Key Features

• 10-ton cooling capacity in a single packaged rooftop cabinet
• Gas/electric configuration combines heating and cooling in one assembly
• High-heat designation supports larger heating loads typical in commercial applications
• 460-volt, 3-phase power supply for commercial electrical infrastructure
• Self-contained design simplifies rooftop installation and service access

Compatibility

Designed as an OEM commercial packaged rooftop gas/electric unit intended for light commercial and commercial ducted HVAC systems requiring 10-ton capacity at 460-volt, 3-phase electrical service.

Installation Notes

Installation must be performed by a licensed commercial HVAC contractor in accordance with local mechanical codes, the International Mechanical Code (IMC), and the International Fuel Gas Code (IFGC). Disconnect and lock out all electrical power and shut off the gas supply before beginning any service or installation work on this unit. Rooftop curb alignment, duct connections, and gas piping must be completed before electrical terminations are made. Refrigerant handling requires EPA Section 608 certification.
