NOTE:
Since there is fear of the oil held inside the riser piping flowing back into the compressor when stopped and causing liquid
compression phenomenon, or cases of deterioration of oil return, it well be necessary to provide a trap at an appropriate
place in the riser gas piping.
A trap is not necessary when the outdoor unit is installed in a higher position than the indoor unit.
