8.7 Avoiding slugging
ATTENTION Slugging can damage the compressor and cause refrigerant to
To prevent slugging:
The complete refrigeration system 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 superheat at the compressor input should be min. 7 - 10 K. (check the setting
of the expansion valve). For LG compressors see chapter 5.3.
The system must reach a state of equilibrium.
Particularly in critical systems (e.g. several evaporator points), measures are recommended such
as replacement of liquid traps, solenoid valve in the liquid line, etc.
There should be no movement of coolant whatsoever while the compressor is at a standstill.
The use of a check valve is strongly recommended. Otherwise, there is a risk of reverse
condensation which may damage the compressor.

8.8 Connection of oil level regulator
F
Oil level regulation systems have proven themselves with parallel circuits of several compressors.
The connection "0" is provided for installing an oil level regulator (see dimensions drawing). All
E
common oil level regulators from AC&R, ESK and Carly as well as the OM3 TraxOil oil level regulation
system from Alco can be connected directly without adapters (see Fig. 17). A sight glass on the oil
level regulator is not required.
