Example)
• Outdoor unit model : A7UW40GFA0 [FM40AH UO2]
• Total indoor units combination : 7k + 7k + 7k + 7k + 9k + 9k = 46k

3. The rated capacities above show the rise in the total indoor unit capacity when operating 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 16~52 kBtu/h(40%~130%)
5. At least two indoor units should be connected.
