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.
ATTENTION! Improperly installed pipes can cause cracks and tears which can
result in a loss of refrigerant,
A rule of thumb:
Always lay the first pipe section starting from the shut-off valve
downwards and
parallel to the drive shaft.

4.3 Pipes
Pipes and system components must be clean and dry inside and free of scale, swarf and layers of
rust and phosphate. Only use air-tight parts.
Lay pipes correctly. Suitable vibration compensators must be provided to prevent pipes being
cracked and broken by severe vibrations.
Ensure a proper oil return.
Keep pressure losses to an absolute minimum.
