1
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 must 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.
Due to our policy of continuous product innovation, some specications may change without notication.
