1.3 General safety instructions
WARNING Risk of accidents.
Refrigerating compressors are pressurised machines and as such
call for heightened caution and care in handling.
The maximum permissible overpressure must not be exceeded,
even for testing purposes.
Risk of burns!
- Depending on the operating conditions, surface temperatures of
over 60°C on the discharge side or below 0°C on the suction side
can be reached.
- Avoid contact with refrigerant necessarily.
Contact with refrigerant can cause severe burns and skin
damage.
WARNING The compressor may not be used in potentially explosive
environments!

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.
