Moin, has imported an older Ducato 230 camper from the Netherlands. The vehicle has now received full pickup and the yellow gas book. But what surprises me, according to the paper, the system is designed on 50mbar operating pressure, it is also installed a 50mbar pressure regulator. According to the type plate of the Truma heater, the operating pressure is also 30mbar at the Truma Boiler. With the fridge and hob the type plate is no longer legible. I registered a 30mbar system on 50mbar? If not, heating and boiler would have to have a pressure regulator from 50mbar to 30mbar, but I could not find anywhere, would have had to be noticed at the decrease or?
