1
Capacity as rated: 0 ft. above sea level with Piping Length as Main Pipe (16.4 ft.) + Branch pipe
(98.4 ft.) = 115 ft.
0 ft. level difference between outdoor and indoor units.
2
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).
3
Wiring cable size must comply with the applicable local and national codes.
4
The specification may be subject to change without prior notice for purpose of improvement.
5
Sum of connected indoor units capacity is 24~73 kBtu/h.
6
At least two indoor units should be connected.
Due to our policy of continuous product innovation, some specications may change without notication.
