Note :
1. Cooling Capacity is based on : indoor temp.27°C DB, 19°C WB
; outdoor temp. 35°C DB, 24°C WB
2. Heating Capacity is based on : indoor temp.20°C DB, 15°C WB
; outdoor temp. 7°C DB, 6°C WB
3. The rated capacities above show the rise in the total indoor unit capacity when oper-
ating frequency is constant.
Values for changes in capacity are fixed after accounting for variations in operating
frequency and should be used as reference values.
4. Total capacity index of indoor unit should be within 16~54 Btu/h(40%~130%)
5. At least two indoor units should be connected.
Example)
• Outdoor unit model : A7UW42LFA0 [FM41AH U32]
• Total indoor units combination : 7k + 9k + 9k + 9k + 9k = 43k
