Notes (1) Confirm that the flare connectors of the refrigerant pipe connection port on the central flow divide controller is surely closed where indoor unit is not
connected.
(2) Connect the indoor unit to the pipe connection port in sequence from the front right side (*mark in the illustration below) of the central flow divide
controller. (Do not leave the right side port unconnected.)
Ensure to connect from the right side even if the number of indoor units to be connected is less than the number of branches.
