4.7 Laying suction and pressure lines
A rule of thumb:
Always lay the first pipe section starting from the shut-off valve
downwards and
parallel to the drive shaft.
ATTENTION
Property damage possible.
Improperly installed pipes can cause cracks and tears which can
result in a loss of refrigerant.
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.
