6.9 Connection of oil level regulator
The connection "O" is provided for installing an oil level regulator. A corresponding adapter must be
obtained from the trade.
6.8 Avoid slugging
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 min. 15 - 20
K (check the setting of
the expansion valve).
The system must reach a state of equilibrium.
Particularly in critical systems (e.g. several evaporator points), measures such as the use of liquid
traps, solenoid valve in the liquid line, etc. are recommended.
There should be no movement of refrigerant in the compressor while the system is at a
standstill.
