8DGBFEIRu09636-12.2014-DGbFEIRu3| Areas of applicationATTENTION! 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.- Max. permissible ambient temperature 45 °C- Max. permissible discharge end temperature 140 °C- Max. permissible switching frequency 8x /h.- A minimum running time of 3 min. steady-state condition(continuous operation) must be achieved.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!The compressors are filled at the factory with the following oil type:- for R404A/R507 FUCHS Reniso Triton SE 55- for R22 FUCHS Reniso SP 46Compressors with ester oil charge (FUCHS Reniso Triton SE 55) are marked with an X in the typedesignation (e.g. HAX22P/160-4).3.1 Refrigerants• HFKW / HFC: R404A/R507• (H)FCKW / (H)CFC: R223.2 Oil charge3.3 Limits of applicationINFO! For refilling, we recommend the above oil types.Alternatives: see lubricants table, Chapter 7.5.The oil level must be in thevisible part of the sightglass; damage to the com-pressor is possible if over-filled or underfilled!max. oil levelmin. oil levelATTENTION!Fig. 4
