Power wiring is field supplied 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 ft of refrigerant line per indoor unit and a 0 ft level differ-
ence between outdoor and indoor units.
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) and 75ºF wet bulb (WB).
Heating capacity rating 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).
1
Power Input is rated at high speed.
2
All power/communication cables to be minimum 18 AWG, 4-conductor, stranded, shielded and must
comply with applicable and national code.
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 3745 and are the
same in both cooling and heating mode. These values can increase due to ambient conditions during
operation.
