ATTENTION Compressor operation is possible within the operating limits
showninthediagrams.Pleasenotethesignicance
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 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 maximum current and power consumption must not be

application limit can therefore be limited.
When operating in the vacuum range, there is a danger of air
entering on the suction side. This can cause chemical reactions,
a pressure rise in the condenser and an elevated compressed-gas
temperature. Prevent the ingress of air at all costs!
