Note (1) If the number of indoor connected units is less than the number of branches, connect in sequence
from the front right side. Tighten securely the flare connectors not in use.
(2) Always attach an accessory strainer at the outdoor discharge gas connection port.
(3) Flow divide controllers cannot be installed upside
down. Install them so that the indoor unit is level.
(4) If space of 400 or more is available above the flow
divide controller (* mark), inspection ports can be
located at the points shown in the figure right.
(Change the position of the relay box.)
(5) Weight: 17kg

coupling selected from the table below depending
on the capacity of the indoor unit to be connected.
(Use the flare nut attached to the flow divide controller.)
