●Multiple indoor units under group control can utilize a solenoid valve kit in common.

●Categories of connected indoor unit capacities are determined by the solenoid valve kit.

Type of solenoid valve kit	Total capacity of indoor units (BTU/h)
160	19.000 < Total capacity < 54.600
56	7.500 < Total capacity < 19.000

●If the capacity range is exceeded, use 2 solenoid valves connected in parallel.
