5. Be careful of the connecting arrangement of the header unit and follower units. Set the outdoor units in order of
capacity from the one with the largest capacity. (A (Header unit)
• Be sure to use a header unit for the leading outdoor unit to be connected to the main pipe. (Figure 1, 3 and 6)
• Be sure to use a T-shaped branch joint (RBM-BT14FE/RBM-BT24FE: separately purchased) to connect each
outdoor unit.
• Be careful of the direction of the Outdoor unit connection piping kit for the liquid side. (As shown in Figure 2, a
Outdoor unit connection piping kit cannot be attached so that the refrigerant of the main pipe ows directly into
the header unit.)
• When attaching a Y-shaped branch unit for the outdoor unit connection piping kit, attach it level with the
ground (Be sure not to exceed ±15 degrees.). Regarding a T-shape branch joints for the liquid side, there is no
restriction for its angle.
