This data is rated 0 ft above sea level, with 25 ft of refrigerant line per indoor unit and a 0 ft level
difference between outdoor and indoor units. All capacities are net with a combination ratio between
Cooling capacity rating obtained with air entering the indoor coil at 80ºF dry bulb (DB) and 67ºF wet
bulb (WB) and outdoor ambient conditions of 95ºF dry bulb (DB).
Heating capacity rating obtained with air entering the indoor unit at 70ºF dry bulb (DB) and outdoor
ambient conditions of 47ºF dry bulb (DB) and 43ºF wet bulb (WB).

1Power Input is rated at high speed.
2Take appropriate actions at the end of HVAC equipment life to recover, recycle, reclaim or destroy
R410A refrigerant according to applicable regulations (40 CFR Part 82, Subpart F) under section 608
of CAA.
3Sound Pressure levels are tested in an anechoic chamber under ISO Standard 3745.
4All communication cable to be minimum 18 AWG, 2-conductor, stranded, shielded and must comply
