(c) Height difference between the indoor unit being configured and the lowest indoor unit is >98.4 ft, or pipe length difference between the outdoor unit
and the furthest indoor unit and the outdoor unit and the indoor unit being configured is > 360.9
ft.
(d) Height difference between the indoor unit being configured and the lowest indoor unit is 49.2–98.4 ft, or pipe length difference between the outdoor
unit and the furthest indoor unit and the outdoor unit and the indoor unit being configured is 164–360.9
ft.
Example: If the unit being configured is 60 ft away from the outdoor unit, and the furthest in door unit is 300 ft from the outdoor unit, the pipe length
difference is 240 ft (300-60=240), so Digit 10 should be set to “2.”
