Program Scope
This program applies to unitary air-conditioners, air-source unitary heat pumps, single packaged and split systems; and air-conditioning coils (and air-handling products with air-conditioning coils) and heat pump coils (and air-handling products with heat pump coils) that a coil-only manufacturer rates as a system with other manufacturer’s outdoor units that are rated below 65,000 Btu/h cooling.
Where a:
- Unitary Air-Conditioner is one or more factory-made assemblies ordinarily including an evaporator or cooling coil(s), compressor(s), and condenser(s) and may include a heating function.
- Air-Source Unitary Heat Pump is one or more factory-made assemblies ordinarily including an evaporator or cooling coil(s), compressors(s), condenser(s), and a heating function.
- Single Packaged System is a system in which all components are integrated into one cabinet.
- Split System is a system in which components are provided in separate assemblies but are designed to be used together.
