Thresholds should not be selected as designor continuous operating points.- 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.Avoid continuous operation near the threshold.For operation with supplementary cooling:- Use only oils with high thermal stability.For operation with capacity regulator:- The suction gas superheat temperature may need to be reducedor set individuallywhen operating near to the threshold.When operating in the vacuum range, there is a danger of airentering on the suction side. This can cause chemical reactions, apressure rise in the condenser and an elevated compressed-gastemperature. Prevent the ingress of air at all costs!The compressors are filled with the following oil type at the factory:- for R134a, R404A/R507, R407C 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. FX16/2051).3.1 Refrigerants• HFKW: R134a, R404A/R507, R407C• (H)FCKW: R22NH3: R7173.2 Oil charge3.3 Operating limitsINFO!
