ATTENTION! Slugging can result in damage to the compressor and cause

  refrigeranttoleak.

To prevent slugging:

The complete refrigeration plant must be properly designed.

All components must be compatibly rated with each other with regard to output (particularly the

evaporator and expansion valves).

Suction gas superheating at the compressor input should be > 10 K (check the setting of the

expansion valve).

There should be no movement of refrigerant in the compressor while the system is at a

standstill.
