4.5 Laying suction and pressure lines
A rule of thumb:Alwayslaytherstpipesectionstartingfromtheshut-offvalvedownwards and
parallel to the drive shaft.
ATTENTION Improperly installed pipes can cause cracks and tears, the result
being a loss of refrigerant.
INFO Proper layout of the suction and discharge lines directly after
the compressor is integral to the system’s smooth running and
vibration behaviour.
