4.4 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.

4.5 Laying suction and pressure lines

ATTENTION Improperly installed pipes can cause cracks and tears, the result
INFO
A rule of thumb: Always lay the first pipe section starting from the shut-off valve downwards and
parallel to the drive shaft.
Rigid
fixed point
The pipe connections have graduated inside diameters so that pipes with
standart millimetre and inch dimensions can be used.
The connection diameters of the shut-off valves are rated for maximum
compressor output. The actual required pipe cross section must be
matched to the output. The same applies for non-return valves.
being a loss of refrigerant.
Proper layout of the suction and discharge lines directly after
the compressor is integral to the system's smooth running and
vibration behaviour.
