1
Power Input is rated at high speed.
2
Low Ambient Wind Baffle Kit allows operation down to 0°F in cooling mode.
3
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.
4
Sound Pressure levels are tested in an anechoic chamber under ISO Standard 1996.
5
Power/communication cables from the outdoor unit to the indoor unit to be minimum 18 AWG, 4-conduc-
tor, stranded, shielded or unshielded (if shielded, it must be grounded to the chassis at the outdoor unit
only) and must comply with applicable and national code.
6
Piping lengths are equivalent.
Power wiring to the outdoor unit is field supplied, solid or stranded, and must comply with the applicable
local and national codes.
This unit comes with a dry helium charge.
This data is rated 0 ft above sea level with 24.6 of refrigerant line per indoor unit and a 0 ft level
difference outdoor and indoor units.
Cooling capacity rating 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).
Heating capacity rating obtained with air entering the indoor unit at 70ºF dry bulb (DB) and 59ºF wet bulb
(WB) and outdoor ambient conditions of 47ºF dry bulb (DB) and 43ºF wet bulb (WB).
