8DGBFE96181-01.2015-DGbFEI3| Areas of applicationThe compressors are filled at the factory with the following oil type:FUCHS Reniso Triton SE 55Compressors with ester oil charge (FUCHS Reniso Triton SE 55) are marked with an X in the typedesignation (e.g. HGX6/1410-4 R134a).3.1 Refrigerants• HFKW / HFC: R134a3.2 Oil chargeINFO! For refilling, we recommend the above oil types.Alternatives: see lubricants table, Chapter 7.5.The oil level must be in the visiblepart of the sight glass; damageto the compressor is possible ifoverfilled or underfilled!ATTENTION!Fig. 3max. oil levelmin. oil levelATTENTION! Compressor operation is possible within the operating limitsshown in the diagrams. Please note the significanceof the shaded areas. Thresholds should not be selected as designor 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:- The suction gas superheat temperature may need to be reducedor set individually when operating near to the threshold.For operation with frequency converter:- The maximum current and power consumption must not beexceeded. In the case of operation above the mains frequency,the application limit can therefore be limited.When operating in the vacuum range, there is a danger of airentering on the suction side. This can cause chemical reactions,a pressure rise in the condenser and an elevated compressed-gastemperature. Prevent the ingress of air at all costs!3.3 Limits of application
