PERFORMANCE DATA
Rated Heating Combination Tables
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
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).
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.
