ATTENTION Property damage possible.
The oil level must be in the
visible part of the sight
glass; damage to the com-
pressor is possible if overfil-
led or underfilled!

ATTENTION Compressor operation is possible within the operating limits
shown in the diagrams. Please note the significance of the shaded
areas. Thresholds should not be selected as design or continuous
operation points.
- Permissible ambient temperature (-20°C) - (+60°C).
- Max. permissible discharge end temperature 160°C.
- Min. oil temperature
≥
30°C.
- Min. pressure gas temperature
≥
50°C.
- Max. permissible switching frequency 8x /h.
- A minimum running time of 3 min. steady-state condition
(continuous operation) must be achieved.
For operation with frequency converter:
- Frequency range 25-70 Hz
- The maximum current and power consumption must not be
exceeded. In the case of operation above the mains frequency,
the application limit can therefore be limited.
3.3 Limits of application
