Table 15: Value table for soaking
To soak the layers of contamination on the turbine, the cartridge group can be immersed verti-
cally in a container (02) with fluid.
Place the container (02) inside a larger container (03) so that the overflowing fluid can be

collected.
Selection of the cleaning agent
Cleaning agents which contain chlorine attack metals.
Use only pH-neutral cleaning agents which do not attack metals.

Fill the container (02) with soaking fluid. To shorten the soaking time, the fluid can be

heated up to a maximum of 60 ºC.
