- 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frequencyconverter:

- The potential control range of the compressor is 30-70 Hz.

- Max. permissible current consumption must not be exceeded.

For operation with capacity regulator:

- The suction gas superheat temperature may need to be

reduced or set individuallywhen operating near to the threshold.
