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%.
Rated cooling capacity obtained with air entering the indoor unit at 80ºF dry bulb (DB) and 67ºF wet
bulb (WB) and outdoor ambient conditions of 95ºF dry bulb (DB) and 75ºF wet bulb (WB).
Rated heating capacity obtained with air entering the indoor unit at 70ºF dry bulb (DB) and 60ºF wet
bulb (WB) and outdoor ambient conditions of 47ºF dry bulb (DB) and 43ºF wet bulb (WB).
At least two indoor units should be connected. For allocated capacity information, see the combination

Sound pressure levels are tested in an anechoic chamber under ISO Standard 3745 and are the
3
same in both cooling and heating mode. These values can increase due to ambient conditions during
operation.
All power wiring minimum 3-conductor, stranded, shielded, and must comply with applicable local and
4
national codes. For detailed electrical information, please refer to electric characteristics on page 279.
Piping lengths are equivalent.
