**** Cartridges tends to stick to valve body after some months in service and might be damaged when unmounting. Prefer to
remove cartridges only when it must be replaced. Cartridges must not be unmounted for troubleshooting investigations but
only when exchange is really required. Report to chapter 10.3. Magnum valve cartridge, page 88 for complete troubleshooting
guide and to chapter 9.6.12. Cartridge replacement, page 83 for proper assembly/disassembly procedure.
