EEV: Electronic Expansion Valve, IDU: Indoor Unit, ODU: Outdoor Unit. 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 difference 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.
Cooling range can be extended from 5°F down to -4°F
using the Low Ambient Wind Baffle Kit (sold separately)
2 All
communication / connection (power) cable from the outdoor unit to the indoor unit
are field supplied and is to be a minimum four-conductor, 14 AWG, stranded, shielded or
unshielded (if shielded, it must be grounded to the chassis of ODU only), and must comply
with applicable local and national codes.
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.
5 Piping lengths are equivalent.
