1 Rated in accordance with AHRI standard 270 (2015). AHRI Standard 270 establishes a method of rating outdoor unitary equipment in terms of Sound Power.
2 Rated in accordance with AHRI standard 275 (2010). AHRI Standard 275 provides the calculations for estimating the A-Weighted Sound Pressure at a given distance from the equipment. That is a
more useful number because that is what humans will hear.
3 Based only on distance factor; other factors may change this value such as:
- Unit location (reflective surfaces adjacent to the unit)
- Barrier shielding sources
- Sound path/elevation
- Outside noise sources

Purpose
Prevents liquid migration to the compressor especially for high liquid riser
applications
Enables cooling demand down to 30 °F. Will require freeze stat, CC heater
and TXV
Delays compressor start 5-7 minutes to prevent short cycling
Scroll compressors usually do not require hard start; maybe needed for utility
brown-out or low voltage areas
Prevents liquid migration to compressor in cold weather
Lowers compressor sound level
Protects the compressor if refrigerant charge is too low
TXVs provide superior refrigerant flow control, comfort and efficiency
compared to pistons
Protects the compressor at low suction pressure conditions
