The gas pipe is the pipe at the compressor discharging side. Horizontal sections of the liquid pipe should be
sloped down from the compressor with a slope of at least 1:100 (10 mm down for each 1 m run). The gas pipes
should be insulated where they are routed in the conditioned space.

pipe connector of the outdoor unit shown in Figure 2-16.
