INFO
For refilling, we recommend the above oil types.
Alternatives: see lubricants table, Chapter 7.5
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.
- Permissible ambient temperature (-20°C) - (+60°C)
- Max. permissible discharge end temperature 140°C.
-Max.permissibleswitchingfrequency12x/h.
- 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 capacity regulator:
- Continuous operation, when the capacity regulator is activated,
is not permissible and can cause damage to the compressor.
- The suction gas superheat temperature may need to be reduced
or set individually when operating near to the threshold.
- When the capacity regulator is activated, the gas velocity in the
systemcannotundercertaincircumstancesensurethatsuf-
cient oil is transported back to the compressor.
Foroperationwithfrequencyconverter:
- 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.
