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

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.
