4.4 Laying suction and pressure lines
INFO! Proper layout of the suction and pressure lines directly after the
compressor is integral to the smooth running and vibration behaviour
of the system.

result in a loss of refrigerant.
A rule of thumb:
Alwayslaytherstpipesectionstartingfromtheshut-offvalvedownwards and
