Table 21: LMU36CHV with Ducted Indoor Units — Rated Cooling Combination Table.
1
Capacity as rated: 0 ft. above sea level with 25 ft. of refrigerant piping.
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
At least two indoor units should be connected.
*A 1.3 multiplier is necessary for the calculation of total combination.
