The two key rings underneath the Multiplier are associated with the pressure valves and should not be removed (L) These rings help maintain the integrity and functionality of the pressure valves.
If you need to perform tank maintenance and are unable to run the tank vent process, you can pull the ring tab to drain the tanks (M). However, please note that doing so will result in a loud noise and your hands may get wet due to the moisture buildup in the tanks.
