Compressor assembly
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 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.

4.7 Operating the shut-off valves
Before opening or closing the shut-off valve, release the adjustable valve spindle seal by approx.
¼ of a turn counter-clockwise.
After activating the shut-off valve, re-tighten the adjustable valve spindle seal clockwise.

6.5 Laying suction and discharge 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 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.
