General Data
Table 22: Standard Wall-Mounted (SB Frames) Indoor Unit General Data.
EEV: Electronic Expansion Valve
Power wiring is field supplied and must comply with the applicable local and national codes.
This unit comes with a dry nitrogen charge.
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
95-105%.
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).
1
Power Input is rated at high speed.
2
Take 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.
3
