ATTENTION! Compressor operation is possible within the operating

of the shaded areas. Thresholds should not be selected as design
or continuous operating points.

- 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 30-70 Hz.
- Max. permissible current consumption must not be exceeded.
At max. rotation speed therefore, the application limit can
be reduced.
- Use a thermal protection thermostat.
- Do not operate an additional capacity controller.

- Consultation with GEA Bock.
Foroperationwithcapacityregulator:
- The suction gas superheat temperature may need to be
reduced or set individuallywhen operating near to the threshold
When operating in the vacuum range, there is a danger of air en-
tering 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!

INFO!
For refilling, we recommend the above oil types.
Alternatives:see lubricants table, Chapter 7.5.
The oil level must be in the
visible part of the sight
glass; damage to the com-
pressor is possible if over-
filled or underfilled!
