Note: Main pipe L1 can be selected form table 2 and table 3, the larger size should be finally selected.
The straight distance between copper pipe turning and the contiguous branch pipe is at least 0.5m.
The straight distance between the contiguous branch pipes is at least 0.5m.
The straight distance which the branch pipes connected to the indoor unit is at least 0.5m.

If ODU connect only one IDU, the capacity of IDU should be not more than ODU.
If ODU connect more than one IDU, the capacity of each IDU should be not more than 8kW for refrigerant uniform distribution.
When capacity of indoor unit greater than the sum of 100%, capacity of indoor unit will be attenuated.
When capacity of indoor unit greater than or equal to the sum of 120%, in order to ensure the effectiveness of machine, and then try
to open the indoor units at different time.
