heater
Check functioning and rotation direction of the circulation pump
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
bar)
Check setting of the thermostat mixing valve.
Check the function of the balancing vessel: Remove the valve flap.
Press in the valve pin briefly using a matchstick. The balancing vehicle
is OK if air comes out. If water comes out, then the balancing vessel
needs to be replaced. If nothing comes out, then use a car air pump to
pump in air in the balancing vehicle according to the values on the type
plate.
