3.2 Oil charge

INFO For refilling, we recommend the above oil types.

Alternatives: see lubricants table, Chapter 8.5.

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.

- 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.

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!

3.3 Limits of application

ATTENTION The oil level must be in the

visible part of the sight glass;

damage to the compressor is
