Nominal capacity is rated 0 ft. above sea level with corresponding refrigerant piping
length in accordance with standard length of each outdoor unit and a 0 ft. level difference
between outdoor and indoor units. All capacities are net with a combination ratio between
95 – 105%.
Nominal 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).
Nominal 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).
2
This unit comes with a dry helium charge.
3
Acceptable operating voltage: 187V-253V.
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
All power wiring / communications cable to the IDUs be minimum 18 AWG, 4-conductor,
stranded, shielded or unshielded (if shielded, must be grounded to chassis at ODU only)
and must comply with applicable local and national codes.
