When you install the gas pipe horizontally, make sure you form a 1/250 down
gradient (2cm down for a length of 5m) to facilitate refrigerant flows.
Insulate the liquid and gas pipes. If you combine the liquid and gas pipes for
insulation, then heat exchanges between them will degrade the compressor
performance significantly.
