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 (reective 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 60M52 Prevents liquid migration to the compressor especially for high liquid
riser applications
Low ambient HP units (cooling operation) All models 54M89 Enables cooling demand down to 30 °F. Will require freeze stat, CC
heater and TXV.
Mild ambient (heating operation) All models 11B97 Enables heating demand above 60 °F ambient
Cold weather Control Board Integrated Feature To allow unit to operate at very low ambient conditions (older models).
Board integrated feature on new models
Fossil Fuel Kit (Heat Pump Only) All models 1.841185 Required for furnace with heat pump installations
Hard Start 24 & 36 10J42 Scroll compressors usually do not require hard start; maybe needed
for utility brown-out or low voltage areas
Hard Start 48 & 60 81J69
Crankcase Heater 18, 24, 30 93M04
Prevents liquid migration to compressor in cold weather
Crankcase Heater 36, 42, 48, 60 Factory Installed
Sound Cover Factory Installed Lowers compressor sound level
Loss of Charge Kit Factory Installed Protects the compressor if refrigerant charge is too low
Additional System Accessories (indoor section)
TXV Kit
18, 24, 30 H4TXV01
TXVs provide superior refrigerant ow control, comfort and eciency
compared to pistons
36, 42, 48 H4TXV02
60 H4TXV03
Outdoor Thermostat - electric heat All models 10Z23 Prevents electric heat operation above specic 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 ow switch All models 11U75 Turn the system o, if condensate water overows due to clogged
drain pipes
Single point power supply All models 21H39 Provide single power source in one junction box
Auxiliary blower relay All models 85W66 Maybe required to select multiple indoor blower speeds
