[. . . ] the pressuresealing tightening of the screws has to be done cross-wise · Install stop valves ahead and following the sludge It is equipped with a sludge and contamination reduction that functions according to the cyclone principle. this guarantees an effective separation of the particles. The sludge and air separator is equipped with a quick bleeder for the air separation. If there is air in the system, it will rise to the highest point of the sludge and air separator. [. . . ] Screw the blind plug in with not too much force If the phosphate cartridge should not be installed until after the startup, then proceed as described in chapter 10. Before starting up, make sure that the ball valve is closed. Increase the water pressure slowly to the operating pressure of the heater (max.
