Check concentration of anti-freezing agent: Take out a little anti-freez-
ing solution from the safety valve and check its correct concentration
using a special tester (6.419-070.0). Target value -25°C
Check pressure in the heating circuit. Nominal value with running cir-
culation pump of the washing station heater 0.07...0.15 MPa (0.7...1.5
