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
