(2) If the pipe length between outdoor unit branch kit and outdoor unit branch kit
(or slave unit) is longer than 2 m, or a lower pipe line exists between outdoor
units, rise for gas pipe should be arranged to eliminate oil from entering into and
remaining at pipes and the stopped outdoor unit. However, there is no need to
provide a rise on the pipe connecting between the master unit and the indoor unit
even if the length exceeds 2m.
