- A minimum running time of 3 min. steady-state condition
(continuous operation) must be achieved.
For operation with additional cooling:
- Use only oils that are highly thermally stable.
- Avoid continuous operation near the limits.
For operation with capacity regulator:
- The suction gas superheat temperature may need to be reduced
or set individually when operating near to the threshold.
Foroperationwithfrequencyconverter:
- The maximum current and power consumption must not be

the application limit can therefore be limited.

pressure rise in the condenser and an excessive compressed-gas
