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).

are the same in both cooling and heating mode. These values can increase due to ambient
conditions during operation.

with all the applicable local and national codes. For detailed information, please refer to
electrical characteristics on page 10.
Communication / connection (power) cable from the outdoor units to the indoor units must
6
be a minimum of 14 AWG, 4-conductor stranded, shielded or unshielded (if shielded, it
must be grounded to the chassis of the outdoor unit only), and must comply with applicable
local and national codes. For detailed electrical information, please refer to electric charac-
teristics on page 10.
Piping lengths are equivalent.
