4.5 Pipes

Pipes and system components must be clean and dry inside and free of scale, swarf and layers
of rust and phosphate. Only use hermetically sealed parts to connect to the compressor and the
refrigeration system.
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.

Improperly installed pipes can cause cracks and tears which can
result in a loss of refrigerant.
Proper layout of the suction and pressure lines directly after
the compressor is integral to the smooth running and vibration
behaviour of the system.
