Install the vibration-proof
rubber so that the bent part
of the fixing leg is
grounded.
The bent part of the
fixing leg is not
grounded.
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) ≥ B ≥ C ≥ D)
• Be sure to use a header unit for the leading outdoor unit to be connected to the main pipe. (Figure 1 and 3)
• Be sure to use a T-shaped branch joint (RBM-BT14E/RBM-BT24E: 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 flows directly into
the header unit.)

Gas piping
• When attaching a Y-shaped branch unit for the gas side, 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.
