Note:
1. Rated capacity at 0 ft. above sea level with 25 ft. of refrigerant line and a 0 ft. level difference between outdoor and indoor unit.
2. Rated cooling capacity obtained with air entering the indoor unit at 80˚F dry bulb (DB) and 67˚F wet bulb (WB) and outdoor ambient conditions of 95˚F dry bulb (DB) and 75˚F wet bulb (WB).
Rated heating capacity obtained with air entering the indoor unit at 70˚F dry bulb (DB) and 60˚F wet bulb (WB) and outdoor ambient conditions of 47˚F dry bulb (DB) and 43˚F wet bulb (WB).
For capacity information, see engineering manual capacity tables. Capacities are based on connection of Non-Ducted indoor units.
3. Sound pressure levels are tested in an anechoic chamber under ISO Standard 3745 and are the same in both cooling and heating mode. These values can increase due to ambient conditions during
operation.
4. All power/communication wiring minimum 4-conductor, stranded, shielded, and must comply with applicable local and national codes.
5. Values when matched with non-ducted units only.
6. Piping lengths are equivalent.
7. Installation of an optional Low Ambient Wind Baffle Kit will allow operation down to -4˚F in cooling mode for applicable outdoor units.
8. Due to our commitment to continued innovation, some specifications may be changed without notification.
