3.2 Oil charge
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.
- Max. permissible discharge end temperature 160°C.
- Min. oil temperature
≥ 30°C
- Max. permissible ambient temperature -30°C - +60°C
- Max. permissible switching frequency 12x /h.
- A minimum running time of 3 min. steady-state condition
(continuous operation) must be achieved.
Avoid continuous operation in limit range.
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
ATTENTION Property damage possible.
The oil level must be in the
visible part of the sight glass;
damage to the compressor
is possible if overfilled or
underfilled!
