[Anticipating additional outdoor units]
1) Ball valve installation position: Install on main tubing after branching.
2) Installation guidelines
• Slope main tubes after branches so as to prevent oil buildup.
• Locate ball valves as close as possible to (within 40 cm) of their branch points.
• If the tube diameter at the ball valve is smaller than that of the main tube after branching, install reducers only at
the ball valve connections.
Caution
When installing outdoor tubing (including that for future indoor expansion), be sure to position the valve service
port to face in the direction of the outdoor unit (see dashed lines in the example above), and at least 50 cm from the
outdoor unit.
