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
SOUND RATINGS
System Accessory Where Used Kit Number Purpose
Liquid Line solenoid All models 60M52Prevents liquid migration to the compressor especially for high liquid riser applications
Low ambient (cooling operation) All models 34M72Enables cooling demand down to 30 °F. Will require freeze stat, CC heater and TXV
Compressor Short Cycle protector All models 47J27 Delays compressor start 5-7 minutes to prevent short cycling
Hard Start 18 10J42 Scroll compressors usually do not require hard start; maybe needed for utility brown-out or low voltage areasHard Start 24 thru 60 88M91
Crankcase Heater 18, 24, 30, 36 93M04
Prevents liquid migration to compressor in cold weatherCrankcase Heater 42 93M05
Crankcase Heater 48, 60Factory Installed
Sound Cover 18, 24, 30, 36 14W00Lowers compressor sound level
Sound Cover 42, 48, 60 14W01
Loss of Charge Kit All models 84M23 Protects the compressor if refrigerant charge is too low
Additional System Accessories (indoor section)
TXV Kit
18, 24, 30 H4TXV01
TXVs provide superior refrigerant flow control, comfort and efficiency compared to pistons
36, 42, 48 H4TXV02
60 H4TXV03
Outdoor Thermostat - electric heat All models 10Z23 Prevents electric heat operation above specific ambient conditions
Outdoor Thermostat - mounting box All models 31461 Mounting box for outdoor thermostat
Freeze stat All models 93G35 Protects the compressor at low suction pressure conditions
Over flow switch All models 11U75 Turn the system off, if condensate water overflows due to clogged drain pipes
Blower time delay All models 58M81 Improves system efficiency and comfort
