of the shaded areas. Thresholds should not be selected as design
or continuous operating points.
- Permissible ambient temperature (-20°C) - (+60°C)
- Max. permissible discharge end temperature: 140°C

- A minimum running time of 3 min. steady-state condition
(continuous operation) must be achieved.
For operation with supplementary cooling:
- Use only oils with high thermal stability.
- Avoid continuous operation near the threshold.
Foroperationwithfrequencyconverter:
- The potential control range of the compressor is 25-70 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.
